The United Kingdom has suspended its extradition treaty "immediately and indefinitely" with Hong Kong after China implemented a new security law, Foreign Secretary Dominic Raab said on Monday.
The move makes the UK the fourth country after Canada, Australia and the United States to suspend its extradition agreement with the partly autonomous Chinese city.
Speaking in the House of Commons, Raab called the suspension a "reasonable and proportionate response" and called the security law "a clear and serious violation" of the UK-China joint declaration that returned Hong Kong from British to Chinese rule in 1997.
"The imposition of this new national security legislation has changed key assumptions underpinning our extradition treaty arrangements with Hong Kong," Raab said.

Raab said he was was particularly concerned about the provision in the new law that allowed mainland China to assume jurisdiction over Hong Kong cases and try those cases in Chinese courts.
"The national security law does not provide legal or judicial safeguards on such cases, and I'm also concerned about the extraterritorial reach of certain provisions."
Raab also insisted that Britain wanted "a positive relationship with China. But we will protect our vital interests, we will stand up for our values, and we will hold China to its international obligations."
'There is a balance'
Earlier on Monday, British Prime Minister Boris Johnson said Britain would be "tough" on China but would not abandon foreign policy engagement with the country.
"There is a balance here. I'm not going to be pushed into a position of becoming a knee-jerk Sinophobe on every issue, someone who is automatically anti-China. But we do have serious concerns," the prime minister said.
Johnson said the changes to the extradition agreement would "reflect those concerns with the security law in Hong Kong."
Last month, China passed a controversial security law in Hong Kong that criminalized subversion, succession efforts and foreign interference. The measure followed more than a year of pro-democracy and anti-China protests in the city.
Chinese Foreign Ministry spokesman Wang Wenbin said on Monday the UK was heading down the "wrong path" and urged London to "avoid further damage to China-UK relations."
Last week, Johnson ordered that Huawei technology be purged completely from the UK's 5G network, backtracking on plans to give the Chinese telecoms giant a limited role in Britain's new high-speed network.
The UK also announced last month it would open a special route to citizenship for up to 3 million eligible Hong Kong residents, a move Chinese Ambassador to Britain Liu Xiaoming has described as a "gross interference" in Chinese affairs.
