US Voices Concerns Over Erosion of Hong Kong's Autonomy From China Nike Ching STATE DEPARTMENT - U.S. officials and lawmakers are voicing grave concerns over the erosion of Hong Kong's autonomy from China, a day after one of the city's largest protests since its handover from British to Chinese control in 1997. Hundreds of thousands of people marched in Hong Kong on Sunday to protest a proposed extradition law that would permit Chinese authorities to request the extradition of individuals to mainland China. "The United States shares the concern of many in Hong Kong that the lack of procedural protections in the proposed amendments could undermine Hong Kong's autonomy and negatively impact the territory's long-standing protections of human rights, fundamental freedoms and democratic values as enshrined in the Basic Law, and the Sino-British Joint Declaration," State Department spokesperson Morgan Ortagus said during a briefing Monday. Washington believes the peaceful demonstration in Hong Kong shows the public's opposition to the proposed amendments. "We are also concerned that the amendments could damage Hong Kong's business environment and subject our citizens residing in or visiting Hong Kong to China's capricious judicial system," Ortagus added. The Hong Kong diaspora and people from more than two dozen cities around the globe also rallied to show solidarity and support the protesters' demands. Observers fear that the extradition bill, if enacted, would be used by Beijing to grab individuals it couldn't otherwise apprehend, including human rights advocates and other critics of the Chinese Communist Party based in Hong Kong. .
