Beijing has proposed new national security legislation that could see mainland intelligence agencies set up bases in Hong Kong with enforcement powers that foreign diplomats fear could potentially put rights and freedoms at risk.
"We are monitoring the situation closely and expect China to respect Hong Kong's rights and freedoms and high degree of autonomy. As a party to the joint declaration, the UK is committed to upholding Hong Kong's autonomy and respecting the one country, two systems model," Johnson's spokesman said.
