On 21 May 2018, during the resumed session of the Committee on Non-Governmental Organizations in the UN, the Chinese delegation claimed that Isa had been "participating, inciting and funding separatism and terrorism for years", adding that while participating in regional dialogues at UNPFII he had indicated that he was "representing WUC instead of STP", despite only having accreditation as an STP representative. "All the above actions seriously violates relevant rules and regulations of the United Nations," the letter said, urging the Committee on Non-Governmental Organizations "to uphold the authority of the UN Charter and withdraw the consultative status of STP".
