Thanks to its regulatory powers, robust digital economy, and active foreign and security policy, the European Union is one of the key players in cyberspace. The EU strongly promotes the position that international law, and in particular the United Nations (UN) Charter, applies in cyberspace. As a complement to binding international law, the EU endorses the voluntary non-binding norms, rules and principles of responsible State behaviour that have been articulated by the UN Group of Governmental Experts. It also encourages the development and implementation of regional confidence building measures, both in the Organisation for Security and Co-operation in Europe and other regions. On a bilateral level, the EU has established cyber dialogues with strategic partners to reinforce the exchange of good practices, lessons learnt and further the idea of responsible state behaviour in cyberspace.

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.

In recent years, Bosnia and Herzegovina has seen a consistent increase in the rate of Internet absorption along with a continuous extension of broadband access across urban and rural areas. As a potential EU candidate country, Bosnia has recently developed a burgeoning drive to advance the country’s digital and cyber capabilities in line with those of the European Union; ‘smart growth’ is notably included as one of the national priorities under the 2015 Strategic Framework. That said, the institutional, regulatory, and operational framework that would enable the realisation of this ambition is still nascent and the progress in many policy areas is undermined by the complexity of the distribution of powers between the central government and two entities: the Federation of Bosnia and Herzegovina and the Republika Srpska. In 2017, Bosnia formally adopted the Policy of Electronic Communications of Bosnia and Herzegovina 2017-2021, which is largely aligned with the Digital Agenda of Europe [x]. This vision of a Bosnian digital society is a key milestone for the country’s emerging cyber diplomatic apparatus as it clearly identifies the foundational pillars of the country’s ICT ecosystem, which in turn will assist in bringing it into closer alignment with European cyber priorities.

Under the auspices of the UN, the EU and its Member States have consistently reaffirmed that a universal cyber security framework can only be grounded in existing international law, including the Charter of the United Nations in its entirety, international humanitarian law, and international human rights law. 
Addressing issues as to how existing international law and international humanitarian law, including the principles of humanity, necessity, proportionality and distinction, apply to the use ICTs by States is necessary to increase accountability and transparency. International humanitarian law is fully applicable in cyberspace and this should not be misunderstood as legitimising the use of force between states in the cyber domain. The EU has typically opposed calls for the need to adapt existing international law as a means to develop a new legal instrument for cyber issues.

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.

At the first substantive session of the 2021-2025 UNGGE, recalling its status as a potential candidate of the EU, Bosnia and Herzegovina aligned itself with the EU’s statement that the existing corpus of international law, notably the UN Charter, international humanitarian law, and international human rights law, apply in cyberspace in its entirety. In particular, this includes the principle of state sovereignty, sovereign equality, the settlement of disputes by peaceful means, the provision of the use of force non-intervention in the internal affairs of other states, and the respect for human rights and fundamental freedoms as principles of international law that are applicable to states use of ICTs in cyberspace. [x] Nevertheless, it has consistently refrained from aligning itself with the EU position in a number of key resolutions at the United Nations, including resolutions A/73/27 and A/74/29.

Since 2014, the EU’s ambition has been to act as an ‘honest broker’ on multilateral discussions surrounding issues of cyber governance and norms of responsible state behaviour, aiming to ensure the support and partnership of proactive players in the context of the global debate. The EU has long promoted the need for voluntary, non-binding norms. It believes that norms crystallised under the UN GGE process should generally not be revisited and that progress should be made on matters relating to their implementation. 
Within the OEWG, the EU advanced a suggestion to develop a global repository of existing practice within the United Nations, which would enable UN member states to showcase how they are implementing the voluntary norms of responsible state behaviour, confidence building and other measures.

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.

At the first substantive session of the 2021-2025 UNGGE, Bosnia and Herzegovina aligned itself with the EU’s position that the previous UNGGE and OEWG reports, including corresponding UNGA resolutions adopted by consensus, form the unequivocal basis for “any further discussions on the position, role, and implementation of the voluntary non-binding norms, rules and principles of state behaviour in cyberspace (norms)” [x]. In 2018, however, it voted in favour of Russian-sponsored resolution A/73/27, which launched the Open-Ended Working Group (OEWG) format.

The EU places great importance on cyber resilience and capacity building. Internally, the Union has built a robust legal acquis in relation to the resilience of critical infrastructures, the cornerstone of which rests upon the 2016 Network and Information Security (NIS) Directive and the 2013 and 2019 Cybersecurity Acts. This legal meshwork seeks to integrate cybersecurity into all elements of the supply chain and introduce soft law mechanisms like the EU cybersecurity certification scheme. In doing so, it harmonises national cybersecurity capabilities, cross-border collaboration and the supervision of critical sectors across the EU. 
In the coming months, the Commission intends to add upon the existing cyber-acquis by introducing an array of new initiatives, such as the updated NIS Directive (the so-called NIS2), a proposal on a Critical Entities Resilience (CER) Directive, and a plan to launch a network of Security Operations Centres across the Union. The aim is to create a Union-wide ‘cybersecurity shield’ that will facilitate the detection of cyberattacks and provide an impetus for proactive action. 
This internal buildup of capabilities is supplemented by the development of a specialised ‘cyber diplomacy toolbox’ that allows the Union and its Member States to address cyber incidents through various joint policies, from cooperation and stabilisation measures to restrictive measures and attribution.

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 country has no overarching cybersecurity strategy. Elements of strategic contemplation over cybersecurity can be found within the Criminal Code, which criminalises critical infrastructure damage (including that of information systems) as an act of terrorism. The 2015-2020 Strategy for Prevention and Combating Terrorism reiterates an objective laid out in earlier documents regarding the setup of a dedicated national CERT that will develop and implement monitoring and response mechanisms vis-a-vis the misuse of the Internet for terrorist purposes. Bosnia and Herzegovina has been exploring potential avenues of cooperation with NATO, especially in relation to common solutions to security challenges in the area of cyber defence [x], while Bosnian scientists have also participated in the NATO SPS Programme. Finally, as a member state of the OSCE, Bosnia and Herzegovina is required to implement the OSCE’s 16 Confidence Building Measures (CBMs) as adopted by the OSCE Permanent Council.

The EU has been an early champion of the Budapest Convention signed under the auspices of the Council of Europe, given the overlapping membership of the two organisations. Much of the EU’s cyber diplomatic efforts have focused on promoting the Convention as the main instrument of choice for fighting cybercrime on a global level. EU member states have consistently opposed Russian bids for replacing this regime with another legal framework. 
The Union is represented in the recently constituted Ad Hoc Committee established by UNGA resolution 74/247 by its Member States and is currently focused on ensuring that the process is inclusive, transparent, consistent with the progress of the UNGGE and OEWG processes, and committed to legal consistency.

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.

Bosnia and Herzegovina is a party to the Budapest Convention on Cybercrime, officially acceding in 2006. As of 2019, however, domestic legislation at the state level had only been partially harmonised with Budapest provisions [x]. The country voted against the Russian-sponsored UN resolution that launched the institutional procedure for a new legal instrument on international cybercrime cooperation. Bosnian law enforcement regularly cooperates with Europol and is due to open negotiations for a cooperation agreement with Eurojust [x].
