The Foreign Ministry on Tuesday said it would impose visa restrictions on US personnel who are deemed to have "behaved poorly" on Hong Kong-related issues.

Foreign Ministry spokesperson Mao Ning said Washington had grossly interfered in China's internal affairs and seriously violated principles of international law and basic norms of international relations by imposing visa restrictions on Chinese officials over Hong Kong matters.

"China has decided to impose visa restrictions on US personnel who have behaved poorly on Hong Kong-related issues. We must emphasise that Hong Kong is China's Hong Kong, and Hong Kong affairs are purely China's internal affairs. We urge the US side to genuinely respect China's sovereignty, Hong Kong's rule of law, and cease any form of interference in Hong Kong affairs," Mao said at a news conference in Beijing.

Washington had last month said it would impose fresh sanctions on Hong Kong officials responsible for implementing the SAR's national security law following the jailing of 45 people for subversion.
