of Interactive Media Strategies believes Microsoft could win big with Skype By communicationtransformation.blogspot.com Published On :: Fri, 13 May 2011 22:01:00 +0000 Interactive Media Strategies (IMS) is a market research firm that follows streaming media. They discuss the news of Microsoft’s $8.5 billion acquisition of Skype, and the prospects for Skype to emerge as a viable platform for business video communications. Their research compares usage levels for a range of social media and communications applications, including Skype, YouTube and Facebook. Here is a link to the video. They report that personal use of Facebook and YouTube is relatively high but that has not yet translated into comparable levels of corporate use. They believe this raises the question of whether YouTube and Facebook will be able to outgrow their focus on the consumer side of the business to compete in the enterprise market. Usage levels for Skype are significantly lower overall, but Skype’s penetration in business communications is higher than they see for other communications apps online among young users most likely to experiment with emerging technologies. IMS puts forth the opinion that if Microsoft could make it easier for technology laggards to embrace Skype - i.e. integrate Skype with the Microsoft Office suite - then Skype could achieve significant enterprise adoption.

of Watching the Corners: On Future-Proofing Your Passion By www.43folders.com Published On :: Tue, 18 May 2010 00:59:56 +0000 On May 16, 2010, at 10:02 AM, "Xx" wrote: You mentioned you gave a talk at Rutgers about future proofing your passion. Is this available as a podcast? I'd love to listen! This poor kid emailed me to ask a really simple question. And I went and saddled him with the world's most circuitously long-winded answer. Surprise, surprise. Hey, Xx, Thanks for the note, man. No I'm sorry its not up as audio AFAIK. FWIW, it's a talk I'm asked to do more often lately so I wouldn't be surprised if it turns up sooner or later. Since you were kind enough to ask, the talk—which comes out super different each time I do it— consists of a discursive mishmash of advice I wish I'd had the ears to hear in the year or five after graduating from college: primarily, that we never end up anywhere near where we'd expected, and that most of us would have been a lot happier a lot faster if we'd realized that we were often obsessing over the wrong things—starting with how much the world should care about our major. ("Liberal Arts," with a concentration in [ugh] "Cultural Studies," thanks.) The talk started as a way to encourage students to learn enough about what they care about that any temporary derails and side roads wouldn't scare their horses too badly. But, today, I see it as something a lot bigger that's demonstrably useful to anyone who hopes to survive, evolve, and thrive in this insane world. A handful of bits I'm (obviously) still synthesizing into something notionally cohesive: My Kingdom for Some Context! For myself, I wish I'd known the value of developing early expertise in interesting new skills around emerging technologies (rather than just iteratively pseudo-honing the 202-level skills I thought I "understood"). Alongside that, I wish I'd learned to embrace the non-douchier aspects of building awesome human relationships (as against "networking" in the service of landing some straight job that, as with most hungry young people, locked me into a carpeted prison of monkey work at the worst time possible). Also how I wish I'd paid more attention to events, contexts, relationships, and change that were happening outside my immediate world —rather than becoming, say, the undisputed master of fretting about status, salary, and whether I was "a success" who had "arrived". Hint: I was not a "success," and I had not, by any stretch, "arrived." To my mind, "success" in the real world is much more the equivalent of achieving a new personal best; it's not about whether you won the "Springtime in Springfield SunnyD®/Q105™ 5k FunRun for Entitilitus," and got a little ribbon with a gold crest on it. Truly, pretty much anyone who feels they've "arrived" anyplace is about to learn a) how much more they could be doing outside the narrowness of an often superficial ambition and b) the surprising number of things they had to give away through the opportunity costs and trade-offs that lead up to every theoretical milestone. It's a real goddamned thistle, and it's more than a little depressing. Do You Still Really Want to be a Fireman? [N.B.: I really hope you're taking bathroom breaks here, Xx] Related, I think this is about how being an adult is not only unbelievably complicated in ways that you can't begin to imagine—that it's frequently defined by impossible decisions and non-stop layers of "hypocrisy"—but that there's an invisible but entirely real risk to doggedly chasing the theoretically laudable notion of "following your dream." Especially if it's a dream you first had while sleeping on Star Wars sheets in a racecar bed. Not because it's a bad idea to want things or to have ambitions. Quite the opposite. More because, for a lot of us, the "dreams" of youth turn out to be half-finished blueprints for wax wings. And not particularly flattering ones at that. By starting adult life with an autistically explicit "goal" that's never been tested against any kind of real-world experience or reality-in-context, we can paradoxically miss a thousand more useful, lucrative, or organic opportunities that just…what?…pop up. Often these are one-time chances to do amazing and even unique things—opportunities that many of us continue to reject out of hand because it's "not what we do." It took me a full decade to learn to embrace the unfamiliar gifts that kismet loves to deliver on our busiest and most stressful days, and which gifts might (maybe/maybe not) even end up bringing the real-life, non-racecar-bed, now me a big step closer to something that's 1000 times more interesting than a hollow, ten-year-old caricature of "what I wanna be when I grow up." Finding Your "Old Butcher" Also related, it strikes me that the indisputable wealth of information and options that are provided by the web often comes with a harrowing hidden tradeoff. While we can certainly learn a lot on our own and become (what feels like) an instant expert on any topic in an afternoon, we usually do so in the absence of a mentor and outside the context of applying expertise to solve actual problems. In my opinion, a cadet should have to survive more than a few Kobayashi Maru scenarios before he gets to declare himself, "Captain." Call it a guru, a wizard, an old butcher, or what have you, the mad echo chamber of a young mind often benefits from the dampening influence of an experienced grownup who can help you understand things that raw data, wikipedia entries, and lists of tips and tricks can't and wont ever do. We benefit from a hand on the back and a gentle voice, reminding us: "Try not to obsess over implementation until you really understand the problem," or "Worry more about relationships than org charts or follower counts," or "Don't quit looking after you've found that first data point," or—my favorite— "Spend less time fantasizing about 'success' and way more time making really cool mistakes." Conversely, though, I think this means that everything we think we know, as well as all the fancy advice that gets thrown around—absolutely including the material you're reading now—is the product of what one person knows and what another person has the ears to hear. For us. For now. For who really knows what. But it is a transaction that takes place in a very specific time and within the bounds of a set of "known" "facts." So, fair warning, doing your own due diligence never hurts. What's Almost Not Impossible? [N.B.: I swear to God this ends at some point, Xx] One big pattern for "future-proofing" your passion? Keep your eyes open and your heart even "opener." And, be more than simply tolerant of the notion of change—sure, take it as read that nothing is ever fixed in place for more than a little while. But, to the extent that your sanity can bear it, always keep an eye on the corners, the edges, and especially learn to watch for those infinitesimally tiny figures starting to shuffle around near the horizon. Because a lot of the things that seem ridiculously small and inconsequential right now will eventually cast a shadow that people will be chasing for decades. It's just that we're never sure which tiny figure that will turn out to be. So, yeah. It really is true that no one but you cares about your major. But, trust me: everybody is interested in the person who repeatedly notices the things that are about to stop being impossible. Be the curious one who soaks in all that "irrelevant" stuff. And, even as you stay heads-down on the "now" projects that keep the lights on, remember that the guy who invented those lights made hundreds of "failed" lightbulbs before fundamentally upending the way we think about time, family, industry, and the role of technology in how we live and work. But, yes, first he "failed" a lot a lot at something which more than a few of his contemporaries thought was pointless in the first place. Ask: What's out there right now that's about to stop being impossible? Where will it happen first? Who will (most loudly and erroneously) declare it's total bullshit? Who will mostly get it right—but possibly too early? Who will figure out what it means to our grandkids? Who will figure out how to put it in everyone's front pocket for a quarter? Y'know who? I'll tell you who: practically anybody BUT that guy in the racecar bed who wants to talk about his major. Important: Merlin's Advice is Only Future-Proof to 10 Meters A few years back, most watch manufacturers decided to come clean and stop categorically declaring that their timepieces were "waterproof." Instead, today, the more credible vendors admit their product is merely "water-resistant"—and, even then, they'll only guarantee the underwater functionality at so many meters, and for so long, and under thus and such conditions. Truthfully, the same applies here. Nothing can actually "future-proof" anything. Anyone who claims to know the future is either a madman, a charlatan, or, often as not, both. Thing is, regardless of the passions (or goals or values or priorities or whatever) that we hope to protect or defend, we'd all do well to remember that it is still ultimately OUR passion that's at stake. That means we're the only one responsible for seeing that its functional components survive and adapt in a world in which each one of us has just north of zero control. If we embrace the fact that no one can or should ever care about the health of our passions as much as we do, the practical decisions that help ensure Our Good Thing stays alive can become as "simple" as a handful of proven patterns—work hard, stay awake, fail well, hang with smart people, shed bullshit, say "maybe," focus on action, and always always commit yourself to a bracing daily mixture of all the courage, honesty, and information you need to do something awesome—discover whatever it'll take to keep your nose on the side of the ocean where the fresh air lives. This is huge. Anything else? Yeah. Drink lots of water, play with your kid every chance you get, and quit Facebook today. No, really, do it. Thanks again for the note, Xx, and sorry for the novella. I'll ping you if the audio ever turns up.

of The new geopolitics of nuclear power By www.chathamhouse.org Published On :: Tue, 27 Sep 2022 18:05:33 +0000 The new geopolitics of nuclear power The World Today mhiggins.drupal 27 September 2022 States may be looking to build or restore nuclear plants, but they will need to bypass Chinese and Russian sector dominance, says Sung-Mi Kim. Against the backdrop of a worldwide energy crisis, the global nuclear market may be seeing a renaissance with growing interest in nuclear energy. Sceptics are being compelled to rethink the trade-off calculus of nuclear power for the first time since the 2011 Fukushima disaster, which prompted countries to postpone or phase out nuclear power. The nuclear option is again being seen as a way of boosting a nation’s energy autonomy and its ability to weather the volatility caused by unpredictable Russian gas supplies. Russia supplies more than a third of global nuclear fuel-related services Adoption or expansion of nuclear energy capability will not allow a country to be free of Russian influence entirely given its dominant presence in the global nuclear sector. Rosatom, Russia’s state-controlled power corporation, and its subsidiaries, make Russia the leading exporter of nuclear power plants. Russia also supplies more than a third of the global fuel-related services, namely uranium conversion and enrichment. Notably, Russia has been capable of building these into an attractive financial package for importing countries, backed by generous state support. Like Russia, Chinese government-owned nuclear corporations have started to make forays into export markets as part of its Belt and Road Initiative and ‘Go Out’ policy, which encourages companies to invest overseas. Both China and Russia have a strong comparative advantage in offering competitive state-backed financing schemes for nuclear products and services. In the meantime, nuclear investment in advanced economies in the West have tended to remain stagnant. The International Energy Agency reports that of the 31 reactors built in the past five years, 27 are of Russian or Chinese design. Given current market conditions and the technological complexity of the nuclear fuel cycle, new entrants will find it difficult to acquire energy autonomy through nuclear power. They will have to rely on foreign suppliers to build, operate and maintain their nuclear plants and supporting infrastructure. It typically takes a decade to build a nuclear plant and start generating electricity, and nuclear plant deals are built on a decades-long commitment of the parties to forge a political, technical, regulatory and scientific partnership that goes beyond purely commercial terms. Nuclear export, therefore, is often a long-term, whole-of-the-government effort involving diplomatic skills and geopolitical calculations, and is subject to global oversight to ensure the peaceful use of nuclear energy. The US is building strategic nuclear partnerships In response to the Russian and Chinese dominance of the civilian nuclear sector, American nuclear industries are asking the government to streamline the export-licensing process and provide them with support. The US government is also establishing strategic partnerships with nuclear-capable allies such as South Korea to win procurement contracts. South Korea has recently made a U-turn in its nuclear policy. Its new president Yoon Suk-yeol intends to revive the role of nuclear power to help meet the country’s climate targets and has vowed to export 10 nuclear power plants by 2030. In Japan, where nuclear energy production was halted after the Fukushima nuclear meltdown, a new policy platform was launched in 2019 to enhance public-private collaboration for nuclear research and development. Intensifying geopolitical tensions between the US and its allies on one side, and Russia and China on the other, will inevitably affect nuclear market dynamics. Domestic economic slowdowns and international sanctions will be a stress test for the export potential of Russia and China. For instance, in May 2022, Finland eliminated Rosatom from its consortium to build a nuclear power plant, citing delays and increased uncertainties stemming from the invasion of Ukraine. In 2020, Romania cancelled its nuclear deal with China, instead securing an agreement with the US to build two more reactors for its Cernavoda plant. The decision was seen as a move to align Romania with US intentions to sideline China. In March 2022, when the Czech Republic officially launched a tender to build a new reactor at the Dukovany nuclear plant, Rosatom and Chinese state-controlled nuclear exporter CGN have been excluded from the tender on security grounds. As countries try to wean themselves off price-volatile gas and decarbonize their economies to meet climate targets, new commercial opportunities are opening up for the nuclear industry. At least 15 countries are building reactors, according to the World Nuclear Association. Some, such as China, are building more than one. More than 30 countries are considering, planning or starting a nuclear programme. There is also a growing need for replacing or extending the lives of ageing reactors. It is in this context that the commercial, geopolitical and regulatory aspects of nuclear energy will play an increasing role in the geopolitical contest for money and influence. Full Article
of China’s high-stakes incursion in the heights of Bhutan By www.chathamhouse.org Published On :: Wed, 28 Sep 2022 11:18:27 +0000 China’s high-stakes incursion in the heights of Bhutan The World Today mhiggins.drupal 28 September 2022 Why is Beijing establishing settlements over the Bhutanese border? To undermine India’s strategic security, say John Pollock and Damien Symon. A confrontation is fomenting on the roof of the world in a country that rarely warrants international attention. In the tiny Kingdom of Bhutan, China is building villages in isolated, mountainous regions, upping the pressure on the capital Thimphu to yield contested areas to Beijing. In doing so, China risks a collision with South Asia’s largest state and Bhutan’s principal security guarantor, India. Sitting on top of fragile geopolitical fault lines in the Himalayas, China’s Central Military Commission has seemingly authorized a series of incursions into the Bhutanese regions of Doklam, Jakarlung, and Pasamlung. Beijing has also announced fresh claims in the east towards Sakteng. Taken together, these amount to 12 per cent of Bhutan’s total territory according to Nathan Ruser, an analyst at the Australian Strategic Policy Institute. India is wary of Beijing’s increased assertiveness in the Himalayas following a large-scale incursion by the Chinese People’s Liberation Army (PLA) into Ladakh two years ago when dozens of Indian and Chinese soldiers were killed in a stand-off. The appearance of Chinese roads, villages and a host of other infrastructure projects within largely uninhabited areas of Bhutan close to Tibet, have, for sections of India’s national security establishment, confirmed their worst fears – Beijing is altering the status quo across the Himalayas in a bid to undermine India’s strategic security through territorial alterations. As a country of only 780,000 people, Bhutan is greatly influenced by New Delhi when it comes to its foreign affairs. In exchange, India guarantees the defence of the kingdom and trains the Royal Bhutanese Army. The appearance of Chinese villages on its territory risks Bhutan becoming a victim of the wider regional tensions. The trauma of China-Bhutan border relations Bhutan is no stranger to the territorial aspirations of its northern neighbour. Thousands of refugees fled into the country after China annexed Tibet, damaging longstanding cultural and religious links between the Tibetan and Bhutanese people – a trauma still being felt today. Now, Beijing is laying claim to three areas within Bhutan, including Doklam in the west. This plateau is close to the Siliguri Corridor which connects to the ‘Seven Sister’ states in northeast India. Indeed, such is India’s concern over any Chinese presence near Doklam that in 2017 local Indian commanders sent troops into Bhutan to prevent PLA engineers building a road near the Doka La pass, resulting in a 72-day stand-off on Bhutanese soil between India and China, an experience Thimphu is unwilling to repeat. Once again, China is looking to force the border issue unilaterally, altering the status quo and building villages and outposts on Bhutanese soil. On the available evidence, it has been doing so for at least three years. The presence of Chinese villages in uninhabited areas of Bhutan serves a strategic purpose. They appear to be intended to pressure Bhutan into accepting an earlier version of a border deal that concedes Doklam to the Chinese. Bhutan’s increasing concern is that China now views the Sino-Bhutanese border dispute as a way of unravelling India’s strategic position by stealth. Here we see a growing pattern of behaviour across the Himalayas. China is testing the boundaries in isolated and contested areas of India to attain local advantages that ensure New Delhi’s gaze remains fixed on the Himalayas. The costly choice facing Bhutan Bhutan for its part has very deliberately opted to remain silent, despite clear violations of its border deal with Beijing. Thimphu has made no public comment on any of the Chinese incursions. The choice now facing Bhutan is a costly one. To concede Doklam would devastate relations with India, its closest partner. But to ignore China’s ambitions would be to risk further violations of its sovereign territory. Bhutan may yet agree in principle to a land swap but then delay its implementation in the hope China limits any further advances. Thus Bhutan, India and China stand at a crossroads, with an impending confrontation that has not yet arrived and one that through Thimphu’s delicate diplomacy, Bhutan hopes never does. China’s incursions into Bhutan — Key to map: 1 - Pangda; 2 - Dramana and Shakhatoe; 3 - Menchuma Valley. Areas of incursion are circled; the red shaded areas are disputed. The star is the capital Thimphu, and the international airport lies to the west. 1. Pangda — Aerial image of Pangda, a village of some 124 people established by China which sits 2km over the border with Bhutan. Image: Maxar (March 2022). The most high-profile incursion is in the disputed areas in Doklam. Running adjacent to the previous Doka La stand-off site, a series of Chinese projects are visible, following the Amo Chu River that runs from the Chumbi Valley in Tibet into Bhutan. The most well-known of these xiaokang – meaning peaceful and prosperous – border projects is Pangda, a village of 124 people that sits roughly two kilometres within Bhutan from the border. First spotted by open-source intelligence analysts in October-November 2020, Chinese state media says that 27 households were moved from the Shangdui village to Pangda in September of that year and that the village is located in Yadong County, Tibet. Pangda, however, lies on territory internationally recognized as belonging to Bhutan. Since Pangda was first identified, two more villages and an additional excavation site have been noted through satellite photographs taken in March this year, steadily following the river further into Bhutanese territory. In recent reporting by journalist Vishnu Som, a connecting road is also visible that runs 9km into Bhutan. Given the geopolitical sensitivities of the area vis-a-vis India, speculation points to Chinese attempts to increase pressure on the Jampheri ridge overlooking the 2017 stand-off site, which according to journalist Tenzing Lamsang, is currently occupied by a small Royal Bhutanese Army detachment. As ever in the Himalayas, small tactical alterations have strategic implications. Chinese control of the Jampheri ridge would command views towards Sikkim, increase the scope of China’s surveillance operations near the border and place India’s Eastern Theatre Command at a terrain disadvantage were it to intervene as it did at Doka La. 2. Dramana and Shakhatoe — Aerial image showing one of several villages recently built by China in the Dramana and Shakhatoe region of Bhutan. The Chinese military is said to be patrolling this area aggressively. Image: Maxar (2022). Further north of Doklam, at Dramana and Shakhatoe, more villages have been identified, with recent photographs taken in November 2021 showing a collection of structures nestled between snow-capped mountains. Varying in size, the largest village identified by journalist Devjyot Ghoshal comprises more than 84 buildings with construction having been started in December 2020 and seemingly completed by December 2021. Little is known about the nature of these villages or their occupants other than their size and location. However, the Chinese PLA has patrolled these areas aggressively, warning away Bhutanese herders and challenging counter patrols by the Royal Bhutanese Army. A permanent PLA presence in the area would be a significant change to the status quo. Informed speculation suggests that these may house either civilian contractors brought in from Tibet to oversee construction projects in the area, Tibetan or Chinese citizens brought across the border, or they could even be barracks for the PLA to help facilitate increased patrols in these contested areas. 3. Menchuma Valley — Aerial image of one of several Chinese-built settlements in and around Menchuma Valley in Bhutan; the area is home to holy sites important to both Bhutanese and Tibetan culture. Image: PlanetLabs (2022). Amid the sustained activity in the west of Bhutan, we are seeing similar levels of activity mirrored in the northern contested areas in Jakarlung, Pasumlung and the Menchuma Valley, a well-known entry point into Tibet for Bhutanese pilgrims. In May 2021, a team of researchers led by Robert Barnett from the London School of Oriental and African Studies discovered three additional villages in these contested areas, alongside a series of infrastructure projects, sitting between 3km and 5km south of the Chinese border in Bhutan. Barnett identified what appears to be police and military posts near these villages, as well as a communications tower. While the building efforts at Doklam are seen as having a geopolitical intent towards India, these villages and their locations are seemingly aimed to maximize China’s leverage over Bhutan. They are considered sacred in Tibetan Buddhist teachings as the birthplace of ancient Himalayan cultural heroes, with strong links to the Bhutanese royal family. Today they are the home to holy sites and temples, such as the Singye Dzong. For China to intrude on this area, and in some cases even deny entry to parts of it, is suppression of Bhutanese history, culture and traditions. By design or by default, Beijing is managing Tibetan religion and culture beyond the borders of the Tibetan Administrative Region. Full Article
of China's Party Congress: a dose of foreign policy realism is needed By www.chathamhouse.org Published On :: Tue, 11 Oct 2022 14:01:32 +0000 China's Party Congress: a dose of foreign policy realism is needed The World Today mhiggins.drupal 11 October 2022 In the final article of three on the 20th Chinese Communist Party Congress, which opens on 16 October, Yu Jie argues that Beijing must show more pragmatism about Taiwan and the West. How important is foreign policy at the congress? The political reports delivered to the delegates of the week-long 20th Chinese Communist Party Congress, which happens every five years, follow a Marxist-Leninist formula. Economics and the means of production form the base, while politics and society fill in the superstructure. We can expect sections on the work of the Chinese Communist Party (CCP), ideological discussion, economics, domestic politics, foreign affairs, cultural reform and social developments. Usually, the report prioritizes big domestic political issues. The political report typically sheds some light on the status of, and relationships between, senior party members. It can also provide insights into the political fortunes of various interest groups. The report acts as a summary of the party’s achievements and its plans – expressed as the lowest common denominator of consensus between competing factions. The congress will address foreign affairs issues with long-lasting implications for the rest of the world This year’s congress should be no different, and the political reshuffle that takes place is likely to signal how Beijing intends to rise to the many challenges at home and abroad. Given China’s growing power and its fraught relationship with the West, this year’s congress is expected to feature serious discussion on weighty foreign affairs issues affecting Beijing, and which will have long-lasting implications for the rest of the world. Which geopolitical issues will be priorities? When it comes to foreign affairs, China’s priorities rarely change. The CCP seeks to create a stable external environment to foster its domestic economic development. This conservative maxim was advocated in the 1980s by China’s then-paramount leader, Deng Xiaoping, and it will continue to guide Beijing’s relationships after this congress. While we don’t know the exact details of this year’s political report, we can expect discussion on relations with the US-led West, a possible shift in the relationship between Beijing and Moscow, and elaboration on China’s ties with the Global South. Notably, it’s likely that a separate chapter of the political report will see Taiwan treated alongside the special administrative regions of Hong Kong and Macau, signalling the party’s commitment to its claims over the contested island. Despite a chorus of nationalistic rhetoric surrounding the issue of Taiwan, Beijing will be careful not to stumble into an international conflict which risks causing colossal damage on all fronts. The choice of language on the so-called ‘Taiwan question’ in this political report will serve as a bellwether as to how, if at all, the party might fundamentally shift its views regarding Taiwan and deviate from the principle of ‘peaceful reunification’, the policy stated at every congress since 1979. How have China’s relations with the West worsened? President Richard Nixon’s visit to China in 1972, the first by an American president to the Communist nation, kicked off five decades of relative stability. However, as China’s global influence has grown, so have Washington’s fears. US-China relations, once stable and cooperative, are now volatile and competitive The relationship has transitioned from the cooperation and relative stability that existed under President George W. Bush and President Hu Jintao in the early 2000s, into one characterized by volatility and competition under Xi Jinping, Joe Biden and Donald Trump. These tensions are almost certain to continue in Xi’s likely third term. Elements of China’s relationship with the West, such as cooperation over military and aviation technology, are becoming far more competitive. At the same time, trade and investment, once viewed as strong ties, have been rapidly deteriorating – as seen, for example, by several major publicly listed Chinese state-owned enterprises and large private companies withdrawing from the New York Stock Exchange. Will Beijing stand by the Kremlin despite Russia’s invasion of Ukraine? At the same time, Beijing’s close relationship with Moscow and its lack of opposition to Russia’s war in Ukraine have put China in an awkward position. The CCP has realized that cooperation with its long-standing ally and neighbour must come with substantial limits to avoid undermining its own political priorities and interests. Russia’s recklessness may spur Xi and the CCP’s senior leadership to minimize the economic, financial and political risks associated with the Kremlin’s pursuit of war against a country aligned with, and supported by, the West. Will China continue to support its regional partners? On its ties with the Global South, Beijing began to rethink its Belt and Road Initiative (BRI) as the US-led Indo-Pacific strategy gained geopolitical momentum. Regions of Southeast Asia and South Asia received a lot of funding and resources for BRI projects, as seen with Chinese support for the China-Pakistan Economic Corridor. Xi also recently introduced the Global Development and Global Security initiatives, which the political report should flesh out. Beijing is fully aware that it can only prosper if its regional partners prosper Beijing is fully aware that it can only prosper if its regional partners prosper, and it can only achieve resource security and border stability if its southern and western neighbours in Myanmar and Afghanistan cease to fight over land and resources. Chinese foreign policy over the last five years has been a strange combination of high-octane rhetoric and patient pragmatism. To respond to this contradiction, the congress could be used as an opportunity to inject a dose of realism. Read the two further articles in this series: the first is a guide to why the Chinese Communist Party Congress matters; the second discusses the key domestic policy themes that Xi Jinping is expected to outline at this year’s congress.

of Analysis of {beta}-lactone formation by clinically observed carbapenemases informs on a novel antibiotic resistance mechanism [Enzymology] By www.jbc.org Published On :: 2020-12-04T00:06:05-08:00 An important mechanism of resistance to β-lactam antibiotics is via their β-lactamase–catalyzed hydrolysis. Recent work has shown that, in addition to the established hydrolysis products, the reaction of the class D nucleophilic serine β-lactamases (SBLs) with carbapenems also produces β-lactones. We report studies on the factors determining β-lactone formation by class D SBLs. We show that variations in hydrophobic residues at the active site of class D SBLs (i.e. Trp105, Val120, and Leu158, using OXA-48 numbering) impact on the relative levels of β-lactones and hydrolysis products formed. Some variants, i.e. the OXA-48 V120L and OXA-23 V128L variants, catalyze increased β-lactone formation compared with the WT enzymes. The results of kinetic and product studies reveal that variations of residues other than those directly involved in catalysis, including those arising from clinically observed mutations, can alter the reaction outcome of class D SBL catalysis. NMR studies show that some class D SBL variants catalyze formation of β-lactones from all clinically relevant carbapenems regardless of the presence or absence of a 1β-methyl substituent. Analysis of reported crystal structures for carbapenem-derived acyl-enzyme complexes reveals preferred conformations for hydrolysis and β-lactone formation. The observation of increased β-lactone formation by class D SBL variants, including the clinically observed carbapenemase OXA-48 V120L, supports the proposal that class D SBL-catalyzed rearrangement of β-lactams to β-lactones is important as a resistance mechanism.

of Mutation of an atypical oxirane oxyanion hole improves regioselectivity of the {alpha}/{beta}-fold epoxide hydrolase Alp1U [Enzymology] By www.jbc.org Published On :: 2020-12-11T00:06:20-08:00 Epoxide hydrolases (EHs) have been characterized and engineered as biocatalysts that convert epoxides to valuable chiral vicinal diol precursors of drugs and bioactive compounds. Nonetheless, the regioselectivity control of the epoxide ring opening by EHs remains challenging. Alp1U is an α/β-fold EH that exhibits poor regioselectivity in the epoxide hydrolysis of fluostatin C (compound 1) and produces a pair of stereoisomers. Herein, we established the absolute configuration of the two stereoisomeric products and determined the crystal structure of Alp1U. A Trp-186/Trp-187/Tyr-247 oxirane oxygen hole was identified in Alp1U that replaced the canonical Tyr/Tyr pair in α/β-EHs. Mutation of residues in the atypical oxirane oxygen hole of Alp1U improved the regioselectivity for epoxide hydrolysis on 1. The single site Y247F mutation led to highly regioselective (98%) attack at C-3 of 1, whereas the double mutation W187F/Y247F resulted in regioselective (94%) nucleophilic attack at C-2. Furthermore, single-crystal X-ray structures of the two regioselective Alp1U variants in complex with 1 were determined. These findings allowed insights into the reaction details of Alp1U and provided a new approach for engineering regioselective epoxide hydrolases. Full Article
