UN Secretary-General António Guterres, smiling and bowing his head, shook hands with Russian President Vladimir Putin, the very person the ICC seeks to arrest.This meeting raises significant moral concerns, epitomizing a blatant disregard for the Ukrainian children who have been forcibly deported amid Russia’s war against Ukraine — charges for which Putin is wanted by the ICC. Beyond the emotional implications, this encounter undermines the principles that the UN itself should uphold.As I argued on EJIL: Talk!, the European Journal of International Law’s blog, in 2013, the UN adopted guidance to regulate meetings between UN Secretariat staff and individuals subject to arrest warrants issued by the ICC. According to these guidelines, there should generally be no meetings between UN officials and persons subject to ICC arrest warrants.
