This paper is trying to examine the basic legal structures of Mainland China and Taiwan, as well as those of Hong Kong and Macao in the Greater China Region, so as to analyze the unique and volatile legal relations among these “entities” in this interesting and fascinating realm full of clashes yet also synergism deeply rooted in both East Asian traditional politics and the recent trend of modernization and globalization. Discussion will be conducted through an observation of constitutional laws, civil laws, criminal laws, property laws, and the “Bill of Rights” issues in the Region. In the conclusion of the paper, a final intriguing question of whether there is any prospect of trying to use legal process to “manage” the troublesome cross-strait relations has also been posed and discussed.
