In June 2017, UN Secretary-General António Guterres appointed Voronkov to serve as the first Under-Secretary-General of the UN Counter-Terrorism Office, which was created on 15 June 2017. It was predicted a Russian would get the position, as Russia was the only one favored to receive the post, as it had been the only permanent member of the UN Security Council that did not have one of its nationals holding a major UN position.[1]
