During a press conference in the White House Rose Garden, Trump announced that he had signed into law the Hong Kong Autonomy Act and also put his signature on an executive order that ends the United States’ preferential treatment of Hong Kong.
"I signed legislation and an executive order to hold China accountable for its oppressive actions against the people of Hong Kong,” Trump said. “No administration has been tougher on China than this administration.”
Trump’s signature on the Hong Kong Accountability Act comes after the legislation was passed overwhelmingly in both the Senate and the House earlier this summer. The act imposes sanctions on entities that help violate Hong Kong's autonomy and financial institutions that do business with them, and comes as a response to the passage of a "national security" law that tightened Beijing's grip on Hong Kong — which has been semi-autonomous from the mainland since 1997.
