South Korea has made significant progress over the last decades when it comes to connectivity and is currently one of the leading states in terms of access and use of ICTs. While in 1995 less than one percent of Koreans used the internet, four years later the country passed the developed nation average and nowadays South Korea is a global leader in the field of connectivity and internet access. Government support for internet access has been instrumental in fostering this progress in connectivity through governmental programs, trainings and low interest loans to companies providing broadband access. Consequently, cyber issues were recognised as important to the bilateral relationship at the EU-South Korea Summit in 2015, and five cyber dialogues have taken place between 2015 and 2020.

The United Kingdom ranks 10^th in the 2021 Network Readiness Index (NRI), 9^th in the 2021 Digital Skills Gap Index and 14^th in the 2021 IMD World Digital Competitiveness Ranking. The British digital sector contributes roughly £149 billion each year to the economy and employs more than 1.5 million people [x]. The country also remains Europe’s unofficial ‘start-up capital’, with British tech startups attracting more than $15 billion in venture capital investment in the midst of a global pandemic. Nevertheless, new and emerging challenges to peace and security in cyberspace represent pressing concerns for the UK [x]. Over the course of 2021, the UK’s National Cyber Security Centre dealt with 777 significant incidents, with around 20% of supported organisations being linked to the health sector and Covid vaccines [x]. In the face of ever-increasing cyber vulnerabilities, the UK government has recently adopted a strategy of ‘levelling up’ protection for British cyberspace. This has brought international collaboration on cyber issues to the forefront of Britain’s diplomatic agenda. British diplomacy has traditionally championed the rules-based international system both online and offline, placing great emphasis on human rights, democratic values and free trade.

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.

As a member of the 2015 Group of Governmental Experts (UNGGE) and as per the Seoul Framework for and Commitment to an Open and Secure Cyberspace, the ROK recognises that international law, and in particular the UN Charter, is applicable in cyberspace and essential for maintaining security and stability as well as promoting an open, secure, peaceful, and accessible ICT environment. 
The country also acknowledges that cybersecurity must go hand-in-hand with respect for human rights and fundamental freedoms as set forth in the Universal Declaration of Human Rights and other international instruments. The ROK notably co-sponsored the Human Rights Council Resolutions 20/8 and 26/13 concerning the promotion, protection and enjoyment of human rights on the Internet. 
The country supports the idea of increasing interstate engagement and exchanging national views on how international law applies in cyberspace, both at the multilateral level as well as at the bilateral and regional levels.

The UK views international law as “a critical tool for ensuring stability and security in cyberspace”. In accordance with the 2013, 2015 and 2021 UNGGE reports as well the 2021 OEWG report, the UK has affirmed that international law, including the UN Charter in its entirety, applies in cyberspace; a position paper notably states that “we do not consider it is for States to pick and choose which international law instruments are applicable”. This includes the prohibition of the use of force (Article 2(4)), the peaceful settlement of disputes (Article 33) and the inherent right of states to act in self-defence in response to an armed attack (Article 51). The law of state responsibility applies to cyber operations in peacetime, including the doctrine of countermeasures in response to internationally wrongful acts. Meanwhile, the country has professed a strong commitment to the respect of human rights law in cyberspace, co-sponsoring the 2012, 2014, 2016, 2018 and 2021 UN Human Rights Council resolutions on the protection, promotion and enjoyment of human rights on the Internet. Likewise, the UK believes in the application of international humanitarian law (IHL) to cyber operations in armed conflict. In response to concerns expressed by other states that this might lead to an undue ‘militarisation’ of cyberspace, the UK has responded that the application of IHL does not encourage armed conflict but only serves to limit humanitarian consequences in the event of such conflict. In addition, the country has stated and that there are ways for cyber capabilities to be developed in a manner “consistent with international law” and called on states to be transparent about the existence of their own capabilities. Those statements do not entirely dismiss the idea of cyberspace as a new military domain, with the British position at the OEWG being that “the use of ICTs in military contexts may be preferable to use of kinetic weapons and can be de-escalatory”. The UK is against the establishment of new, binding international instruments to regulate state behaviour in cyberspace, arguing that “pursuing […] the development of new treaties is only likely to entrench existing divides in this area and will progress us no further on the question of how International Law applies”.

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).

The ROK stands in favour of the adoption and elaboration of voluntary, non-binding norms of state behaviour during peacetime. It strongly upholds the 11 non-binding norms agreed upon in the 2015 UNGGE report and believes that further efforts should be undertaken to clarify and concretise them. 
In addition, the ROK has put great emphasis on the principle of due diligence, consistently demonstrating its commitment through public statements at regional and international forums. The country believes that no new legally binding instrument is necessary for the moment, retaining a preference for the ‘soft law’ approach and maintaining that less resilient states should first focus on building capacity rather than reforming regulatory frameworks.

The UK regards voluntary, non-binding norms of responsible state behaviour as one of the three key pillars upon which the framework for international stability in cyberspace is currently built, the other two being international law and confidence-building measures (CBMs). The British have argued that “stronger awareness and understanding by all countries of the framework in general” is necessary and stated that they “remain concerned that the elaboration of new norms could undermine the existing norms by weakening the overarching protection they provide, or their technology neutral and ‘future-proofed’ nature”. The focus should instead be on the universalisation, operationalisation and implementation of existing norms, with regional organisations and capacity-building efforts playing a central role in this endeavour.

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.”

Driven by a proliferation of cyberthreats originating in the DPRK, Korean diplomats have consistently maintained that bridging the global gap in cybersecurity capabilities constitutes a central task for states; as such, countries should develop cyber defence capabilities to foster resilience in the global cyber ecosystem. 
The South Korean government has introduced several international cooperation mechanisms, especially through the Korean Internet & Security Agency (KISA) and its Global Cybersecurity Centre for Development (GCCD) project. Through the GCCD, South Korea has worked with the World Bank and a series of partner countries in Latin America to organise workshops and exercises. Another important initiative is the Cybersecurity Alliance for Mutual Progress (CAMP) network, a mechanism launched in 2016 that provides a platform for Korea to share its expertise with a large group of partner countries and help them exchange knowledge and best practices.

The July 2021 policy paper on Global Britain in a Competitive Age makes extensive reference to resilience in the post-Covid ICT environment, pledging that the UK will “strengthen global resilience” and “ensur[e] that more resilient countries worldwide can come together through stronger international institutions to act on the most pressing shared challenges”. In the cyber domain, this pledge has been further operationalised by the 2022 National Cyber Strategy, which frames cyber resilience in terms of risk awareness, system security and preparedness. The Strategy prioritises capacity building, adopting a whole-of-government approach and focusing on three elements: protecting critical international supply chains and infrastructure, advancing the secure use of digital technologies and working with industry partners and academia. Since 2016, the UK has worked through the National Cyber Security Centre (NCSC) to adopt an integrated approach to cyber incident management, streamlining across the public and private sectors. Meanwhile, Britain has championed
capacity-building assistance efforts abroad by providing advice, training and exercises and enabling the creation and maintenance of national Computer Security Incident Response Teams (CSIRTs). It has also provided funding to international capacity-building platforms, such as the Forum of Incident Response & Security Teams (FIRST) and the Americas CSIRT network. The UK has been working with partners within the OSCE to encourage the implementation of confidence-building measures (CBMs).

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.

The ROK is generally a strong advocate of strengthening global cooperation against cybercrime. While it is not formally a signatory to the Budapest Convention, the country voted against the Russian-sponsored UNGA resolution calling for a new binding cybercrime treaty. 
To promote cooperation among law enforcement agencies, the ROK’s Supreme Prosecutor’s Office (SPO) convenes regular meetings with the FBI, while also engaging with the Federal Criminal Police Office (BKA) in Germany and the European Cybercrime Centre (EC3) in the Netherlands. 
On the basis of an increased awareness that Internet Service Providers (ISPs) are becoming “important partners to secure electronic evidences”, the SPO works along with Microsoft to operate the Government Security Program (GSP).

According to the 2022 National Cyber Strategy, the UK is committed to promoting the Council of Europe’s Budapest Convention on cybercrime as the primary international instrument for inter-state cooperation, while simultaneously engaging constructively with the UN process to develop a new international cybercrime treaty that will sit comfortably alongside the Budapest regime. In terms of law enforcement, the UK has developed well established mechanisms through the National Cyber Crime Unit (NCCU), operating under the umbrella of the National Crime Agency (NCA). The NCCU is tasked with leading the operational response, coordinating activity across different stakeholders and providing specialist cyber support across the law enforcement domain. The NCA has also developed a network of international liaison officers, which regularly cooperate with Interpol and Europol. Bilateral cooperation with international partners occurs on the basis of the Budapest Convention and associated Mutual Legal Assistance Treaties (MLATs), which facilitate information sharing amongst signatory states. The UK has been an active participant – and has provided voluntary contributions – in the context of discussions for developing a Second Additional Protocol to the Convention to enhance the speed and efficiency of international evidence sharing; the Protocol will be opened for signature in May 2022. The UK has also provided capacity-building assistance to over 100 partner countries, especially in Eastern Europe, Southeast Asia and Africa.

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.
