Prominent Hong Kong activist Joshua Wong has been charged with conspiracy to collude with foreign forces to endanger national security under a Beijing-imposed law that critics say has crushed Hong Kong's once-thriving pro-democracy movement.

Hong Kong police have arrested four men they accused of providing financial support to people who fled overseas and are involved in activities endangering national security, escalating a high-profile crackdown on dissidents in the semi-autonomous Chinese city.

Hong Kong police have offered rewards for information leading to the arrests of eight pro-democracy activists who went into exile abroad and are accused of violating the territory's harsh National Security Law.

A Hong Kong pro-democracy website was temporarily taken down after police warned the Israel-based hosting company that it breached a national security law.

The planned changes to Hong Kong's electoral law give a pro-Beijing committee power to appoint more of Hong Kong’s lawmakers. Last June, Beijing imposed a sweeping national security law on the city and Hong Kong authorities have arrested most of the prominent pro-democracy supporters and outspoken critics. Starting last October, the U.S. had already sanctioned 10 officials including Hong Kong leader Carrie Lam and Deputy Director of the Hong Kong and Macao Affairs Office Zhang Xiaoming.
