 The International Law Commission be requested by the General Assembly to undertake a study of national views and practice on how international law applies in the use of ICTs by States in the context of international security.  [other recommendations]  Member States continue to consider, at the multilateral level, how international law applies in the use of ICTs by States in the context of international security. b) With regard to rules, norms and principles of responsible behaviour of States, reiterating that voluntary, non-binding norms are consistent with international law, and recalling that in 2015 the General Assembly agreed by consensus that all States should be guided in their use of ICTs by the 2015 report of the Group of Governmental Experts, which sets out 11 voluntary, non-binding norms of responsible State behaviour, the OEWG recommends that:  Member States be invited to continue to inform the Secretary-General of their views and assessments on Developments in the field of ICTs in the context of international security and to include additional information on their implementation of international rules, norms and principles of responsible behaviour of States in the use of ICTs.  The Secretary-General be requested to establish a repository of national practices regarding international rules, norms and principles of responsible behaviour of States, which could be further developed into guidance on implementation. The use of surveys or templates on a voluntary basis are encouraged in this regard.  Further guidance on the implementation of norms of responsible State behaviour be developed and widely disseminated at national, regional, interregional and global levels including through the United Nations. States in a position to contribute expertise or resources to the development and dissemination of such guidance are encouraged to do so.  [other recommendations]  Member States continue to consider, at the multilateral level, international rules, norms and principles of responsible behaviour of States. c) With regard to confidence-building measures (CBMs), highlighting that CBMs should be developed and implemented progressively, including at the bilateral, regional and multilateral levels, so as to enhance mutual trust, the OEWG recommends that:  The Secretary-General be requested to establish a repository of CBMs adopted at regional and sub-regional levels to enable the sharing or exchange of information on CBMs and identify potential capacity and resource gaps. The repository would be established in coordination with interested regional and sub-regional bodies and without prejudice to further elaboration of CBMs at the global, regional or sub-regional level.  Members States be encouraged to, on the basis of such a repository, potentially identify the CBMs appropriate to their specific contexts, and cooperate with other States on their implementation. 14
