Isa was expelled from the building on behest of Chinese diplomat and UN DESA Under-Secretary-General Wu Hongbo, who in 2018 defended his action to a studio audience, saying: "When it comes to Chinese national sovereignty and security, we will undoubtedly defend our country’s interests." Despite efforts by the UNPO and the Society for Threatened Peoples, under which Isa and fellow human rights activist Omer Kanat were accredited as participants in the Forum, Isa was not able to re-enter the building. Two days after the incident, on 28 April, he was denied a badge to be able to re-enter the UN and participate in the Forum.
