(Adds China foreign ministry response in paragraph 5)
WASHINGTON, May 6 (Reuters) - The U.S. State Department is delaying a report to Congress assessing whether Hong Kong enjoys sufficient autonomy from China to continue receiving special treatment from the United States, Secretary of State Mike Pompeo said on Wednesday.
Pompeo told a news conference the delay was to allow the report "to account for any additional actions that Beijing may be contemplating in the run-up" to China's May 22 National People's Congress "that would further undermine the people of Hong Kong's autonomy."
The "Hong Kong Human Rights and Democracy Act" approved by the U.S. Congress and President Donald Trump last year requires the State Department to certify at least annually that the former British colony retains enough autonomy to justify the favorable U.S. trading terms that have helped it maintain its position as a world financial center.
Under it, officials responsible for human rights violations in Hong Kong could also be subject to sanctions, including visa bans and asset freezes.
China said it opposed any U.S. interference in its domestic affairs. Foreign ministry spokeswoman Hua Chunying made the comments Thursday at a daily press briefing.
Hong Kong was rocked in 2019 by months of massive, and sometimes violent, political protests over a now-withdrawn extradition bill that would have allowed people to be sent to mainland China for trial and calls for greater democracy.
China's Hong Kong affairs office warned earlier on Wednesday that the city will never be calm unless "black-clad violent protesters" were all removed, describing them as a "political virus" seeking independence from Beijing.
Riot police dispersed a crowd of 300 pro-democracy activists late last month, the first sizable protest since the government imposed a ban on public meetings at the end of March to curb coronavirus infections.
The arrests of 15 activists in April, including veteran politicians, a publishing tycoon and senior barristers, thrust the protest movement back into the spotlight and drew condemnation from Washington and international rights groups.
Britain returned Hong Kong to China in 1997, and the territory was promised a "high degree of autonomy" for 50 years, something that has formed the basis of the territory's special status under U.S. law.
