China’s involvement in UN peacekeeping contributions has been on the rise for some time. China is also stepping up its own military and security operations abroad to protect its commercial and strategic interests, particularly in Africa. In doing so, China is exposing itself to a more complex set of issues – including international legal issues – with which it is only just starting to grapple.

China’s contribution to UN peacekeeping over the last 10 years has expanded dramatically. In September 2016, it pledged $1 billion to help fund UN peace, security and development activities, while in 2018 it supplied 10.3 per cent of the UN peacekeeping budget, up from 3.93 per cent in 2012. China is also the largest contributor of peacekeeping forces among the five permanent members of the Security Council. As well as its regular troop contributions, it has also established a stand-by rapid deployment force of 8,000 peacekeeping troops.

For China, increased involvement in UN peacekeeping offers what it likes to refer to as a ‘win-win’ situation. China’s contribution is very valuable at a time when peacekeeping is in need of resources, given the cutbacks from the other four permanent members of the Security Council in both financial and personnel contributions, waning US support for the UN and pressures on the UN budget.

At the same time, the increased role in UN peacekeeping helps to cement China’s image as a ‘responsible stakeholder’ in the international order. China’s contributions to peacekeeping missions also help to promote stability in countries in which China has significant strategic and commercial interests, such as Senegal, South Sudan and Mali. 

China’s increased involvement in UN peacekeeping has coincided with the adoption of a more pragmatic position in relation to its traditionally staunch adherence to the principles of state sovereignty and non-intervention.

China was initially sceptical of the UN’s Responsibility to Protect (R2P) doctrine, endorsed by member states in 2005, which seeks to protect populations from gross human rights violations, and which can include recourse to use of force by the international community, if authorized by the Security Council under Chapter VII of the UN Charter. Over time, though, Beijing has softened its stance to intervention and has gradually acknowledged the ability to respond to humanitarian catastrophes in certain circumstances, for example voting in favour of the Intervention Brigade in the Democratic Republic of the Congo in 2013. 

The softening of China’s stance on non-intervention is also evident in the significant rise not only in the involvement of Chinese troops in UN peacekeeping, but also in the deployment of Chinese military and security forces in a number of African states in order to protect China’s investment and infrastructure projects located there.

In 2017, China established its first foreign naval base in Djibouti, and in 2018 it held military drills in several African countries. The significant increase in China’s military presence in Africa since 2015 gives rise to a number of more complex issues for both China and the local communities involved. According to a recent report, China’s growing military and security presence in Africa is leading to concern in some local constituencies. The fact that China’s state-centric perception of security and development downplays the importance of human rights is likely to compound these tensions on the ground.

New international law implications

The growing presence of Chinese peacekeeping, police and security forces abroad also carries implications for China in a number of different areas of international law with which it has only recently started to grapple. These include the law on the use of force and, given that many Chinese infrastructure projects are situated in fragile states, the law of armed conflict.

The mushrooming presence of Chinese companies and investments abroad also carries implications for the Chinese state, and for the companies concerned, under international human rights law (particularly the UN Guiding Principles on Business and Human Rights). The international law on state responsibility could also be relevant if security companies owned or employed by the Chinese government, where their actions are attributable to China, become complicit in breaches of international law by other governments (such as human rights abuses).

Compared to other areas of international law, such as international economic law and the law of the sea, China has not invested much to date in education in these areas, which may leave it exposed as it increases its global footprint. It was clear from a recent Chatham House roundtable at Columbia Law School in New York that China is now seeking to rapidly upskill in these areas.

China’s global economic and security ambitions appear to be tilting China towards a more interventionist approach, which is extending beyond UN peacekeeping contributions towards security and military missions of its own. Time will tell how China will respond to the challenge of burnishing its image as a good global citizen while maintaining an approach to peacekeeping, security and development which is closely informed by its own economic and security interests.

Technological progress in neurotechnology and its military use is proceeding apace. As early as the 1970s, brain-machine interfaces have been the subject of study. By 2014, the UK’s Ministry of Defence was arguing that the development of artificial devices, such as artificial limbs, is ‘likely to see refinement of control to provide… new ways to connect the able-bodied to machines and computers.’ Today, brain-machine interface technology is being investigated around the world, including in Russia, China and South Korea.

Recent developments in the private sector are producing exciting new capabilities for people with disabilities and medical conditions. In early July, Elon Musk and Neuralink presented their ‘high-bandwidth’ brain-machine interface system, with small and flexible electrode threads packaged into a small device containing custom chips and to be inserted and implanted into the user’s brain for medical purposes.

In the military realm, in 2018, the United States’ Defense Advanced Research Projects Agency (DARPA) put out a call for proposals to investigate the potential of nonsurgical brain-machine interfaces to allow soldiers to ‘interact regularly and intuitively with artificially intelligent, semi-autonomous and autonomous systems in a manner currently not possible with conventional interfaces’. DARPA further highlighted the need for these interfaces to be bidirectional – where information is sent both from brain to machine (neural recording) and from machine to brain (neural stimulation) – which will eventually allow machines and humans to learn from each other.

This technology may provide soldiers and commanders with a superior level of sensory sensitivity and the ability to process a greater amount of data related to their environment at a faster pace, thus enhancing situational awareness. These capabilities will support military decision-making as well as targeting processes.

Neural recording will also enable the obtention of a tremendous amount of data from operations, including visuals, real-time thought processes and emotions. These sets of data may be used for feedback and training (including for virtual wargaming and for machine learning training), as well as for investigatory purposes. Collected data will also feed into research that may help researchers understand and predict human intent from brain signals – a tremendous advantage from a military standpoint.

Legal and ethical considerations

The flip side of these advancements is the responsibilities they will impose and the risks and vulnerabilities of the technology as well as legal and ethical considerations.

The primary risk would be for users to lose control over the technology, especially in a military context; hence a fail-safe feature is critical for humans to maintain ultimate control over decision-making. Despite the potential benefits of symbiosis between humans and AI, users must have the unconditional possibility to override these technologies should they believe it is appropriate and necessary for them to do so.

This is important given the significance of human control over targeting, as well as strategic and operational decision-making. An integrated fail-safe in brain-machine interfaces may in fact allow for a greater degree of human control over critical, time-sensitive decision-making. In other words, in the event of incoming missiles alert, while the AI may suggest a specific course of action, users must be able to decide in a timely manner whether to execute it or not.

Machines can learn from coded past experiences and decisions, but humans also use gut feelings to make life and death decisions. A gut feeling is a human characteristic that is not completely transferable, as it relies on both rational and emotional traits – and is part of the ‘second-brain’ and the gut-brain axis which is currently poorly understood. It is however risky to take decisions solely on gut feelings or solely on primary brain analysis—therefore, receiving a comprehensive set of data via an AI-connected brain-machine interface may help to verify and evaluate the information in a timely manner, and complement decision-making processes. However, these connections and interactions would have to be much better understood than the current state of knowledge. 

Fail-safe features are necessary to ensure compliance with the law, including international humanitarian law and international human rights law. As a baseline, human control must be used to 1) define areas where technology may or may not be trusted and to what extent, and 2) ensure legal, political and ethical accountability, responsibility and explainability at all times. Legal and ethical considerations must be taken into account from as early as the design and conceptualizing stage of these technologies, and oversight must be ensured across the entirety of the manufacturing supply chain.  

The second point raises the need to further explore and clarify whether existing national, regional and international legal, political and ethical frameworks are sufficient to cover the development and use of these technologies. For instance, there is value in assessing to what extent AI-connected brain-machine interfaces will affect the assessment of the mental element in war crimes and their human rights implications.

In addition, these technologies need to be highly secure and invulnerable to cyber hacks. Neural recording and neural stimulation will be directly affecting brain processes in humans and if an adversary has the ability to connect to a human brain, steps need to be taken to ensure that memory and personality could not be damaged.

Future questions

Military applications of technological progress in neurotechnology is inevitable, and their implications cannot be ignored. There is an urgent need for policymakers to understand the fast-developing neurotechnical capabilities, develop international standards and best practices – and, if necessary, new and dedicated legal instruments – to frame the use of these technologies.

Considering the opportunities that brain-machine interfaces may present in the realms of security and defence, inclusive, multi-stakeholder discussions and negotiations leading to the development of standards must include the following considerations:

• What degree of human control would be desirable, at what stage and by whom? To what extent could human users be trusted with their own judgment in decision-making processes?
• How could algorithmic and human biases, the cyber security and vulnerabilities of these technologies and the quality of data be factored into these discussions?
• How can ethical and legal considerations be incorporated into the design stage of these technologies?
• How can it be ensured that humans cannot be harmed in the process, either inadvertently or deliberately?
• Is there a need for a dedicated international forum to discuss the military applications of neurotechnology? How could these discussions be integrated to existing international processes related to emerging military applications of technological progress, such as the Convention on Certain Conventional Weapons (CCW) Group of Governmental Experts on Lethal Autonomous Weapons Systems?

This article sets out to bring sound and music to the field of visual studies in International Relations. It argues that IR largely has approached the visual field as if it was without sound; neglecting how audial landscapes frame and direct our interpretation of moving imagery. Sound and music contribute to making imagery intelligible to us, we ‘hear the pictures’ often without noticing. The audial can for instance articulate a visual absence, or blast visual signs, bring out certain emotional stages or subjects’ inner life. Audial frames steer us in distinct directions, they can mute the cries of the wounded in war, or amplify the sounds of joy of soldiers shooting in the air. To bring the audial and the visual analytically and empirically together, the article therefore proposes four key analytical themes: 1) the audial–visual frame, 2) point of view/point of audition, 3) modes of audio-visual synchronization and 4) aesthetics moods. These are applied to a study of ‘war music videos’ in Iraq and Syria made and circulated by Shi'a militias currently fighting there. Such war music videos, it is suggested, are not just artefacts of popular culture, but have become integral parts of how warfare is practiced today, and one that is shared by soldiers in the US and Europe. War music videos are performing war, just as they shape how war is known by spectators and participants alike.

Peacekeeping missions which have sought to address evolving forms of conflict and instability on the African continent – led by the United Nations, African Union and European Union – have frequently been overstretched.

Across regions including the Sahel, the Horn and West Africa, the issues of violent extremism and criminality – often set against a backdrop of collapsing or severely weakened central states – have led to the mobilisation of a diverse set of new collective responses.

These include notable African-led efforts such as AMISOM in Somalia or more recently the G5 Sahel, where France have played a pivotal role in initiating new and more ad hoc approaches to coalition-building.

As existing multinational missions in Africa continue to evolve on the ground and while new collective opportunities increasingly present themselves, it is critical for policymakers to understand how far such efforts reflect meaningful long-term solutions to the challenges of conflict and insecurity.

At this roundtable event, participants will reflect on how such missions become mobilised and legitimised, the extent to which they can be defined as ‘new’, and whether they represent a truly sustainable means to tackle the issue of conflict in Africa.

This roundtable is held in partnership with Cardiff University and the University of Portsmouth and is supported by the Leverhulme Trust.
