From the Document: "The United States-Hong Kong Policy Act of 1992 (22 U.S.C. 5701, P.L. 102-383) states, 'Support for democratization is a fundamental principle of United States foreign policy.' The development of Hong Kong's Legislative Council, or Legco, has been a fundamental part of Hong Kong's complex and incomplete process of democratization, and as such has become a key concern of some U.S. policymakers. As currently constituted, some of Legco's members are elected via a democratic process, and others are selected by a restricted mandate (see 'Brief History of Legco' below). Under the 1990 Chinese law establishing the governance system for the Hong Kong Special Administrative Region (HKSAR) of the People's Republic of China (PRC), or 'Basic Law,' 'the ultimate aim' is the election of 'all the members of the Legislative Council' (as well as the Chief Executive) by universal suffrage. As a result, Legco plays a critical role in both an assessment of democratization in Hong Kong, as well as progress toward democratization."
