Washington on Wednesday requested an emergency UN meeting over a controversial security law China has proposed for Hong Kong, but Beijing refused to allow it to proceed, according to US diplomats.
The US spelled out its desire for the Security Council session, saying it was "deeply concerned" by Beijing's move, which would ban "sedition" and other perceived offenses in the international finance hub.
Hong Kong activists say that the proposed law effectively abolishes the basic freedoms enjoyed in the city since it was returned to China by the British in 1997.
"Legislation on national security for Hong Kong is purely China's internal affairs," he said.
The US had already announced earlier Wednesday that Hong Kong would no longer enjoy the autonomy promised by China under US law, opening the door to potential trade retaliation.
