The Government has extended its arms embargo to Hong Kong in response to China's national security law.
The UK has had an arms embargo with mainland China since 1989, but that will now include Hong Kong because of extra powers Beijing now has for the security of the territory.
Making the announcement in the House of Commons, Foreign Secretary Dominic Raab said: "The extension of this embargo will mean there will be no exports from the UK to Hong Kong of potentially lethal weapons, their components or ammunition.
"It will also mean a ban on the export of any equipment not already banned which might be used for internal repression such as shackles, intercept equipment, firearms and smoke grenades."
Mr Raab also announced the UK was suspending its extradition treaty with Hong Kong "immediately and indefinitely".
He told the MPs the measures were a "reasonable and proportionate" response to the law introduced by China.
Outling the reasons behind the extradition changes, Mr Raab said the law had "significantly changed key assumptions" about the operation of the system.
He said the legislation gives mainlaind Chinese authorities "the ability to assume jurisdiction over certain cases and to try those cases in mainland Chinese courts".
WATCH: Mr Raab made the announcement in the House of Commons on Monday.
However, he also said the UK wants a "positive relationship" with China.
Mr Raab’s actions came after Prime Minister Boris Johnson promised a "tough" but "calibrated" response to Beijing.
Shadow foreign secretary Lisa Nandy said it is "vital" the world shows a "co-ordinated front" on China and that she was "heartened" to hear Mr Raab has held discussion with partners from the Five Eyes security alliance.
It comes a week after reports that Royal Navy aircraft carrier HMS Queen Elizabeth could be sent to the Far East to counter growing Chinese assertiveness in the region on her first deployment.
