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.

An EU candidate country since 2012, Serbia is an important partner in the Western Balkans. The 2020 iteration of the Digital Evolution Scorecard characterised Serbia as a ‘break out’ economy, meaning that despite a relative lack of digital infrastructure the country is rapidly digitalising; internet penetration is one of the highest across the region, standing at 79%. Over the past decade, Serbia’s digital policy has been focused on attracting foreign investment, deepening the digital transformation across the public and private sectors, and promoting economic growth in line with EU targets. These objectives have been operationalised through a series of strategies, notably the Strategy for the Development of Information Security for the period 2017-2020 and the Strategy for combat against cyber crime 2019-2023. The ITU notes, however, that “while innovative, internet-based e-commerce is expected to bring significant growth and development, obsolete legislation and a lack of harmonisation with EU standards and best practice persist, hampering progress”. As the country becomes increasingly more digitalised, the challenge for Serbian cyber diplomacy will be to develop and enhance avenues of European, regional, and international cooperation.

Brazil is the world’s eighth largest economy in terms of GDP, and by far South America’s most populous and powerful state. While the country has suffered economic and political crises since 2014, it has made significant advances in domestic digitization and played a pivotal, albeit ambiguous role in international negotiations on cyberspace. Brazil has the world’s fifth largest internet user base, after China, India, the United States and Indonesia, and is a leading country in South America when it comes to ICTs usage. The share of Brazilians using the internet has increased from less than 3% of the population in 2000 to more than 68% in 2019. As such, Brazil remains a critical partner for the EU’s efforts to build a secure, stable and rights-based cyberspace.

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 country has not assumed a firm stance on the application of international law in cyberspace. Serbia’s position paper concerning the Open-Ended Working Group (OEWG) highlighted that multilateral dialogue on “information security” must occur “with strict respect for the Charter of the United Nations”. Echoing the stance of states such as China, Russia, and Cuba, Serbia also raised the alarm about the “danger of developing offensive ICT and militarising the digital space”.

In accordance with the output produced by the 2013, 2015, and 2021 consensual reports of the United Nations Groups of Governmental Experts on Developments in the Field of Information and Telecommunications in the Context of International Security (UNGGE), Brazil believes that international law enjoys general applicability in cyberspace. For Brazil, this also includes international humanitarian law and international human rights law. Nevertheless, Brazilian delegations have expressed concern that unqualified transfers of international humanitarian law and an unlimited right of self-defence could legitimise cyberspace as a military domain, while also challenging the protective value of sovereignty and cementing a Western-biased status quo.

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.

Serbia was represented in the 2016-2017 UN Group of Governmental Experts (UNGGE). Despite its EU candidate status, Serbia does not typically vote in alignment with the EU on key cybersecurity resolutions presented before the UN First Committee. Notable examples include UNGA resolution 73/27, which first established the Open-Ended Working Group (OEWG), as well as later resolutions 74/29 and 75/240.

Brazilian diplomats portray Brazil’s role in the often polarised debates on norms of responsible state behaviour as that of a broker or strategic bridge-builder between the different camps rather than a mere ‘swing state’ and highlight that balancing between both camps serves to maintain an independent foreign policy. Brazil sought to focus its chairmanship of UN GGE’s third and fourth iterations on three issues: the role of civilians in cyber conflict, the right to respond, and attribution. Since the 2013 Snowden revelations, the country has been a stark champion of data protection, showcasing exceptional norm entrepreneurship
in relation to cyber-surveillance norms. Brazil has also expressed support for the proposal of adopting a legally binding instrument in the medium to long-term to prevent the militarisation of cyberspace.

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.

Serbia’s legislative framework on cybersecurity is structured upon the 2016 Law on Information Security and its bylaws. The Law ushered in several institutional developments, including the creation of a national CERT in the regulatory agency for electronic communications and postal services (RATEL). The national CERT “monitors the status of incidents on national level, provides early warnings, alerts and announcements, and reacts on incidents by providing the information on affected entities and persons”. [x] It also holds seminars and technical trainings for operators of special importance (critical infrastructure) [x]. 
Meanwhile, the 2021 Cyber Tesla drill (organised in collaboration with the US state of Ohio) constitutes only one example of Serbia’s increased emphasis on critical infrastructure through the prism of cyber defence; the stated objectives included the “construction of military defence system capacities and the National CERT’s capacities for the protection from high-tech attacks, as well as an enhanced cooperation with relevant government and private sector organisations and academic institutions for the purpose of protection of the IT systems”. 
In its UNGGE position paper in 2016, Serbia emphasised the importance of interstate cooperation in “maintaining effective and responsive mechanisms for information exchange, alerts and announcements on cybersecurity incidents”. The paper goes on to posit that “the special focus should be on the protection of critical infrastructure”, especially in the case of transnational attacks. In 2021, Norway donated a platform worth €1.2 million which will “[serve] to hold cyber exercises at the national level enables the real situation of different attack scenarios, and will contribute to capacity building and training of officials in various state institutions”, according to State Secretary of the Ministry of Trade, Tourism and Telecommunications Milos Cvetanovic [x].

Brazil’s 2020 National Cybersecurity Strategy (E-Ciber) outlines ten strategic actions to be undertaken in relation to cyber resilience, which include the extension of international cooperation and the enhancement of protection for critical infrastructure. The Strategy pledges Brazil to encourage international cooperation in cybersecurity, participate in joint cyber resilience events and exercises, and expand cybersecurity cooperation agreements. On the level of discourse, Brazil remains committed to international cyber cooperation in resilience, staying true to its traditional stance in favour of multilateral solutions.

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 Information Society and Information Security Development Strategy for the period 2021-2026 provides a comprehensive approach to the field of information security, which includes both (a) information security of ICT systems of special importance and security of the Republic of Serbia, and (b) security of citizens and businesses, which is particularly reflected through the fight against cybercrime. Its predecessor, the 2017 Strategy for the Development of Information Security, in turn, indicates the fight against cybercrime as one of the government’s five key priorities. 
In light of EU accession negotiations, Serbia has signed and ratified the Council of Europe Convention on Cybercrime (Budapest Convention), including its Additional Protocol on Xenophobia and Racism Committed Through Computer Systems. Nevertheless, the country also voted in favour of UNGA resolution 74/247 calling for an international legal instrument to govern this domain. Domestically, the national legislative framework has been developed in accordance with the Budapest Convention and EU legislation. A High-Tech Crime Unit has recently been established within the special prosecutor’s office, along with three specialised units: crime analysis; terrorism and extremism; and drug prevention, addiction and repression. 
Serbia is a member of Interpol, with which the country has discussed ways to enhance cooperation with regard to combatting cybercrime. Serbia is also gradually developing its own bilateral cooperation network, signing a Cooperation Memoranda with India in 2016 [x] and Romania in 2017 [x] as well as receiving assistance from Russian experts [x].

Brazil originally refrained from signing the Budapest Convention on Cybercrime and had expressed scepticism in response to invitations to accede. The argument advanced was that the treaty is Western-biased and lacking in inclusivity, given that Brazil was not part of the original drafting process. During voting for UNGA Resolution A/74/401, the Russian-sponsored proposal for a new binding Cybercrime Convention, Brazil abstained; during meetings with the BRICS leaders, however, Brazil had endorsed Russian pleas for a new cybercrime instrument to replace the Budapest regime. Upon invitation by the Council of Europe, Brazil finally initiated the process of accession to the Convention in December 2019 and is now an observer country.
