According to CoinMeta, Russian President Vladimir Putin's aide Medinsky announced on the 11th in Abu Dhabi, the capital of the United Arab Emirates, that Russia and Ukraine reached an agreement on the large-scale exchange of captives during the trilateral talks involving Russia, the United States, and Ukraine on that day. The specific details will be made public in the near future. Medinsky stated that both sides reached understanding on some issues and discussed humanitarian matters. The security architecture was a core topic of the Abu Dhabi talks, and the issue of establishing a European security framework proposed by Russia must be resolved. The conflict in Ukraine indicates that the current European security system is functioning very poorly and requires thorough reform.
