China has the largest amount of users in the world, a significant digital economy growth potential, and its national Internet giants Alibaba, Didi, Tencent and Baidu are increasingly able to rival the biggest Western competitors in terms of market value and influence on the global tech landscape. China’s cyber diplomacy puts special attention towards equal participation, the principles of non-interference in internal affairs, non-use of force and peaceful settlement of disputes, and support for multilateral institutions to shape normative views on the governance of cyberspace. However, China’s propagation of the cyber-sovereignty approach to international cybersecurity policy and an absolutist reading of sovereignty in cyberspace provide a legal cloak for state practices that often run counter to the core European values of a global, open, and free Internet.
Japan is a trusted partner and shares the same basic values of human rights, rule of law, and democratic governance. This common set of values also applies to cyberspace as both the EU and Japan have publicly expressed strong support for an open, free and secure internet and the application of international norms to state activities in cyberspace. Japan is also an important trading partner of the EU. The recently adopted Economic Partnership Agreement also reinforces the need for a closer integration of the digital economies. Alignment in broader international economic and political issues is also evident in the field of cyber diplomacy and thus constitutes a strong foundation for close cooperation and partnership.
The United States has historically been a strong partner in cyber diplomacy for the EU based on common values (human rights, rule of law), goals (open, stable and secure cyberspace) and interpretation of international law. Cyber diplomacy with the US has also been operationalised in the form of information-sharing and cooperation to tackle cybercrime, cooperation on cyber defence via NATO and cyber capacity building in third countries. Despite differences over certain foreign policy issues, the EU and the US remain close allies in cyberspace.
In theory, China accepts that the principles enshrined within the UN Charter, including sovereign equality, prohibition on the use of force, settlement of disputes by peaceful means, non-intervention in the affairs of other states and fulfilment of international obligations in good faith, apply in cyberspace.
Nevertheless, the Chinese position is generally characterized by a reluctance to crystallise the precise ways in which existing customary and international treaty law might govern the cyber domain; the exact application of specific aspects of international law, such as laws on self-defence, state responsibility, and international humanitarian law, is claimed to remain unclear in the absence of international consensus.
Chinese delegations have also repeatedly cautioned against the “indiscriminate application of the law of armed conflicts”, arguing that the undue emphasis on jus ad bellum undermines stability in cyberspace by presupposing and thus effectively legitimising cyber conflict, consequently turning cyberspace into a “new battlefield”.
China regards proposals on regional exchanges of views and development of common understanding on the application of international law with particular scepticism, stating that states must work on reaching “universally-accepted consensus” on the application of international law, rather than engage in “self-explanations at regional levels or among a small group of countries”. The Chinese have also consistently favoured the adoption of new international legal instruments tailored to the attributes of cyberspace (lex specialis). Japan has highlighted the importance of promoting the rule of law in cyberspace, noting that cyberspace “should not be a lawless zone”. It further endorses the applicability of international law, in particular the UN Charter, in the cyber domain. In relation to the use of countermeasures, it has stated that it is not necessary for countermeasures to be limited to the same means as internationally wrongful acts.
Japan has cautioned against the launch of “premature” discussions on developing a legally binding new instrument, arguing that the adoption of such an instrument might “roll back” the achievement of past multilateral efforts in confirming the applicability of existing international law in cyberspace. Instead, Japan believes that it is necessary to consolidate, elaborate, and clarify the interpretation of existing treaties and content of customary international law.
During the drafting phase of the 2021 Open-Ended Working Group (OEWG) Report, Japan had proposed to include language explicitly affirming the applicability of State responsibility for internationally wrongful acts, the inherent right of self-defence recognized under the UN Charter, and International Humanitarian Law. The US believes that international law is applicable in cyberspace. As part of the ‘like-minded’ coalition, the US recognises a need to acknowledge the full breadth of relevant international law, including international humanitarian law (IHL), human rights law, customary international law on the responsibilities of states for internationally wrongful acts. The general applicability of IHL in cyberspace is not to be misconstrued as a tacit endorsement of aggression in the cyber domain; instead, it only serves to remind states of the responsibility to respect and protect civilians in the event of armed conflict.
In the context of multilateral fora, US diplomats have specifically emphasised the applicability of the right to self-defence under Art. 51 of the UN Charter, noting that a State may lawfully take cyber-based or non-cyber-based countermeasures in response to internationally wrongful cyber activities attributable to another State, but only subject to the requirements of the doctrine under international law and the principles of necessity and proportionality.

China’s International Strategy on Cyberspace Cooperation highlights that the country is committed to the maintenance of peace and stability in cyberspace through international cooperation on norms of responsible state behaviour. In 2018, Chinese support for the Russia-sponsored UNGA Resolution A/RES/73/27 was instrumental in establishing the Open-Ended Working Group (OEWG) as an alternative forum to the UN Group of Governmental Experts (UN GGE), whose fifth iteration in 2017 had failed to reach consensus.
The country is in favour of formulating new norms of responsible state behaviour in light of recent ICT developments; during the latest OEWG discussions, China put forward specific proposals on formulating new rules on data security, in accordance with its own Global Initiative on Data Security.
China has repeatedly expressed a preference for non-voluntary, binding legal norms, arguing that the best option is to formulate “new international legal instruments consummate with the characteristics of cyberspace, with a view to maintaining peace in cyberspace, instead of using legal instruments as a tool to pursue accountability and punishment unilaterally.” In multilateral fora, Japan has frequently emphasised the need to implement voluntary and non-binding norms of responsible state behaviour in cyberspace. The country believes that any discussion on norm-building should exclusively occur on the basis of the 11 norms affirmed within the 2015 UNGGE Report; possible new norms should be “carefully scrutinised” so as to avoid any change to these 11 norms or duplication with them.
Japan also strongly opposes the adoption of additional legally binding obligations, maintaining that such an endeavour would take a very long time whereas the evolution of technology is extremely fast-paced. Instead, countries should work on parallel mechanisms for capacity-building, raising awareness, and promoting a common understanding of norms. As stated in the 2018 National Security Strategy, the United States views voluntary, non-binding norms of state behaviour during peacetime as essential components of a framework of responsible State behaviour in cyberspace. The US has participated in all iterations of the UN Group of Governmental Experts (UNGGE) as well as the latest Open-Ended Working Group.
In these multilateral fora, US diplomats have typically opposed attempts at shifting to a legally binding status for norms of responsible state behaviour, arguing that such discussions are “premature” and do not represent the best way to address the immediate threats given the fast pace of technological developments.
The starting basis for any further discussions on the part of the US rests on the current buildup of consensus surrounding the norms identified in the 2015 and 2021 GGE reports. Efforts should be concentrated on the implementation of existing consensus norms, not the creation of entirely new normative concepts (i.e. in relation to harmful hidden functions and specific critical infrastructure sectors).

The Chinese International Strategy on Cyberspace Cooperation places a large emphasis on the development of confidence-building measures (CBMs) and engagement with partner countries through predictability-increasing practical measures to prevent unintended conflicts, respond to information operations, and ensure supply chain security in network equipment and industrial control systems.
Another key pillar of China’s cyber strategy is providing capacity-building assistance to developing countries. The Belt and Road Digital Economy International Cooperation Initiative, launched in 2017, and 'the Digital Silk Road' seek to internationalise Chinese technology made by state-owned or affiliated companies, including Huawei and ZTE, and therefore export Chinese technical standards abroad. Chinese outreach in this domain is most active in Africa, South America, and Central and Southeast Asia through projects such as the China-ASEAN Information Harbour and the China-Arabia Digital Silk Road Ningxia Hub. In addition to infrastructure investment, capacity building also focuses on enhancing information-sharing capacities, cyber defence personnel training, and crisis management. Resilience constitutes one of the central objectives of Japan’s 2018 Cybersecurity Strategy, whose core components include international cooperation in sharing expertise and coordination of policies, incidence response, and cyber capacity-building (CCB). Japan has traditionally argued that global initiatives are required to reduce cybersecurity vulnerabilities and has advocated for a tailor-made approach that takes into account the national situation of recipient countries and the importance of national ownership.
Japan recognises the ‘trickle-up’ effect of national initiatives, stating that CCB “not only improves the capabilities of the recipient country, but also directly leads to enhanced security and stability in cyberspace as a whole”; in that sense, it disfavours the understanding of CCB as a “common but differentiated responsibility”, believing that such a view “does not fit the context” of international cyber cooperation. As a result, the country has assumed a balanced approach to CCB. On the one hand, it has successfully utilised multilateral fora such as the G7 and G20 summits to promote its own normative standards.
At the G7 Ise-Shina Summit in May 2016, for instance, Japan introduced the Ise-Shima Principles, which included the enhancement of cooperation on CCB. On the other hand, Japan considers its own security and that of its nationals as intrinsically tied to the cyber capabilities of developing countries, since attacks on the IT infrastructure of regional partners can adversely affect Japanese trade. Japan has thus acted primarily through ASEAN to promote regional capacity-building efforts. The March 2021 Interim National Security Strategic Guidance states that “[the US] will make cybersecurity a top priority, strengthening our capability, readiness, and resilience in cyberspace.” Following the recommendations of the 2020 Solarium Commission, the US government has adopted the concept of ‘layered resilience’ and is gradually rolling out a comprehensive arsenal of resilience measures across a variety of domains.
The US has been active in engaging in strategically-minded capacity building with partners; US capacity building in Africa with organisations such as the African Union and SADC, for instance, have been largely motivated by Washington’s wish to promote an open, secure, and democratic model for Internet governance across the African continent.
In relation to cyber defence, there have been several joint operations and military exercises, both bilaterally (e.g. between the US Cyber Command and the Montenegrin military) and under the auspices of NATO. Recent regional engagement efforts such as the dialogues in the context of the tripartite AUKUS coalition and the Structured Quadrilateral Security Dialogue (the eponymous Quad) also heavily feature references to collaborative cyber-capacity building. In multilateral fora, the US has also welcomed the inclusion of confidence-building measures in the GGE reports and noted that, in order for CBMs to be useful, they need to be implemented at minimum on a bilateral basis and preferably on a multilateral and eventually an international basis.

The Chinese Strategy on Cyberspace Cooperation notes that the country “supports the UN Security Council to play an important part in international cooperation against cyber terrorism” and “supports and contributes to UN effort on fighting cyber crimes”. China is not a party to or observer of the Budapest Convention; instead, it has consistently backed Russian bids in the UN to establish a new cybercrime treaty, with these efforts culminating in Resolution A/74/247 that created an Ad Hoc Committee for that purpose.
China has also signed the World Intellectual Property Organization Copyright Treaty (WIPO Copyright Treaty) in 1985 as well as the UN Convention Against Transnational Organised Crime and is a member of Interpol.
In addition, China has pursued regional avenues of cooperative engagement; within the context of the Shanghai Cooperation Organisation, for instance, the country agreed to participate in efforts to fight against terrorism, separatism, extremism, and international cybercrime.
It also supports joint cybersecurity exercises under the auspices of the Organisation. According to Japan’s 2018 Cybersecurity Strategy, the country is committed to “further [promoting] international partnership through international investigative cooperation and information sharing with international organisations, law enforcement agencies and security information agencies in foreign countries.”
Japan is a party to the Budapest Convention on Cybercrime and mutual assistance treaties (MLAT), voting against the Russian-sponsored UNGA resolution calling for a new binding cybercrime treaty. Japan has pursued dialogues related to cybercrime cooperation in the context of ASEAN, as well as on a bilateral basis with countries like the UK, USA, and Australia. The US is a signatory and an early proponent of the Budapest Convention. A big part of American cyber diplomatic activity has, in fact, been focused on promoting the Budapest regime as the global model of cybercrime governance. In 2019, the US firmly opposed the Russian-sponsored resolution calling for an alternative legal instrument to the Convention; following the passing of the resolution, however, the US has agreed to participate in the Ad Hoc Committee established under UNGA resolution 74/247 despite the fact that the “surprise text” within the May 2021 resolution was seen as an effort to “circumvent dialogue” and undermine the “balanced, inclusive, consensus-based process” sought by the US.
On a multilateral level, the US is also a party to the UN Convention against Transnational Organised Crime (UNTOC) and the Inter-American Convention on Mutual Legal Assistance of the Organisation of American States (OAS) and is a member of Interpol.
Bilaterally, the US has completed an agreement with the UK under the CLOUD Act that facilitates cross-border data sharing directly between US companies and the British government; the US is trying to expand this type of bilateral engagement, currently negotiating a similar agreement with Australia.
