The US imposed sanctions on Hong Kong’s departing police chief and five other officials on Monday, saying they had undermined the semi-autonomous city’s “protected rights and freedoms”, and warned of additional visa restrictions for Chinese officials blocking “reciprocal access” to Tibet.

The sanctions against Hong Kong Police Commissioner Raymond Siu Chak-yee and other high-ranking officials announced on Monday will freeze any assets they have in the US and restrict any financial transactions with them under US law. The sanctions were imposed on Chiu a day before he retires on Tuesday.

Citing an executive order signed by President Donald Trump during his first term, US Secretary of State Marco Rubio said the move showed “the Trump administration’s commitment to hold to account those responsible for depriving people in Hong Kong of protected rights and freedoms or who commit acts of transnational repression on US soil”.
