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.
Costa Rica has played a paramount role in the Organisation of American States as is one of seven American countries that sponsored a
resolution within the framework of the OAS as part of a Working Group on Cooperation and Confidence-Building Measures in Cyberspace. The resolution is inspired by the work of the United Nations Group of Governmental Experts and aims at enhancing interstate cooperation, transparency, predictability, and stability in cyberspace.
