In July 2020, Zenz said an interview with NPR (National Public Radio) that he had previously argued that the actions of the Chinese government are a cultural genocide, not a "literal genocide", but that one of the five criteria from the Genocide Convention was satisfied by more recent developments concerning the suppression of birth rates so "we do need to probably call it a genocide".[183] The same month, the last colonial governor of British Hong Kong, Chris Patten, said that the "birth control campaign" was "arguably something that comes within the terms of the UN views on sorts of genocide." and the Inter-Parliamentary Alliance on China demanded an independent UN investigation. At roughly the same time, U.S. senators Kirsten Gillibrand and Kamala Harris urged the Trump administration to investigate the allegations.[184]
