Trump targets China over Hong Kong security law

President Donald Trump has announced that he will start to end preferential treatment for Hong Kong in trade and travel, in response to a new security law pushed by Beijing.

He described the Chinese government's moves to introduce the measure in Hong Kong as a "tragedy".

Mr Trump also said he was "terminating" the US relationship with the World Health Organization over Covid-19.

China has told the West to "stop interfering" in Hong Kong.

The territory, a former British colony, enjoys unique freedoms not seen in mainland China. But many people there see the looming security law as bringing an end to Hong Kong's special status, agreed under a 1984 agreement between China and the UK.

There are fears the proposed measure - which has sparked a wave of anti-mainland protests - could end Hong Kong's unique status and make it a crime to undermine Beijing's authority in the territory.

This week, Britain said that if China went forward with the law, it could offer British National (Overseas) passport holders in Hong Kong a path to UK citizenship.

On Friday, the UK Home Office confirmed that up to three million people with BNO status could acquire citizenship in this way - as long as they applied for and were granted a passport.

What did President Trump outline?

Mr Trump said that he no longer considered Hong Kong to be separate from China.

"China has replaced One Country, Two Systems with One Country, One System", Mr Trump told reporters in the White House's Rose Garden, in a prepared statement that attacked China on several fronts.

"This is a tragedy for Hong Kong... China has smothered Hong Kong's freedom," he said.

Mr Trump said sanctions would be imposed on Chinese and Hong Kong officials who were believed by Washington to be involved in eroding the territory's autonomy. He did not outline what form these sanctions would take.

He added that the State Department would revise its travel advisory for Hong Kong in light of "increased danger of surveillance" from China.

The president also said the US would suspend the entry of foreign nationals from China identified by the US as potential security risks. There are fears that this could affect thousands of graduate students.

Hong Kong's Justice Secretary Teresa Cheng told the BBC's Chinese Service earlier on Friday that any threat of sanctions was unacceptable.

"Are the sanctions being imposed with a view to coerce another state to change their policy...? Any such sanctions are not going to benefit anyone," she said.

What is the security law about?

China has proposed security legislation which would make it a crime to undermine Beijing's authority in Hong Kong, and could also see China installing its own security agencies in the region for the first time.

China's parliament has backed the resolution - which now passes to the country's senior leadership.

Full details about exactly what behaviour will be outlawed under the new security law are not yet clear. It is due to be enacted before September.

However, it is expected to criminalise:

secession - breaking away from China
subversion - undermining the power or authority of the central government
terrorism - using violence or intimidation against people
activities by foreign forces that interfere in Hong Kong

Experts say they fear the law could see people punished for criticising Beijing - as happens in mainland China. For example, Nobel Laureate Liu Xiaobo was jailed for 11 years for subversion after he co-authored a document calling for political reform.

China's foreign ministry in Hong Kong described US criticism of the new draft law as "utterly imperious, unreasonable and shameless".
