Press Release - Statement from National Security Advisor Robert C. O'Brien
National Security Council
Beijing's recent actions disqualifying pro-democracy legislators from Hong Kong's Legislative Council leave no doubt that the Chinese Communist Party (CCP) has flagrantly violated its international commitments under the Sino-British Joint Declaration and its promises to the people of Hong Kong, including those under the Basic Law. "One Country, Two Systems" is now merely a fig leaf covering for the CCP's expanding one party dictatorship in Hong Kong. The United States will continue to utilize all the powers granted under the Hong Kong Human Rights and Democracy Act, the Hong Kong Autonomy Act, and the Executive Order on Hong Kong Normalization to identify and sanction those responsible for extinguishing Hong Kong's freedom.
