Introduction: The Basic Law,Governance and Electoral Politics in China's Hong Kong and Macao since 1997

1 July 2007 marks the tenth anniversary of Hong Kong's retrocession to Chinese sovereignty to become a Special Administrative Region (SAR) of the PRC. The HKSAR has functioned under the ‘One Country, Two Systems’ framework as enshrined in the Basic Law, its mini-constitution. Upon the resumption of Chinese jurisdiction over Macao on 20 December 1999, a similar ‘One Country, Two Systems’ formula also came into effect for the new MSAR under its Basic Law. The ‘One Country, Two Systems’ formula that guarantees a high degree of autonomy in both Hong Kong and Macao is also a cornerstone of the PRC's strategy toward peaceful reunification with Taiwan. To provide a more balanced and informed understanding of these two Chinese SARs in actualizing the ‘One Country, Two Systems’ model, this special section of four articles adopts a bi-focal approach. On the one hand, it presents in a joint article the views of two leading mainland Chinese legal scholars (Professors Geping Rao and Zhenmin Wang, both National People's Congress Hong Kong Basic Law Committee members) on some vital dimensions of the Basic Law. On the other hand, it offers three articles with a more locally anchored perspective—a comparative analysis (by Professor Sonny Lo) of the contrasting HKSAR and MSAR experiences, and two case studies (by Professors Bruce Kwong and Eilo Yu) that highlight key features of patron–client linkages and informal politics dynamics in HKSAR and MSAR elections and politics.
