This chapter concludes the book by reflecting on the implications of the intertwined origins of colonial Hong Kong and British extradition law. In the final analysis, ideas of extradition actuated local, territorial, and limited common law government in mid nineteenth-century Hong Kong. This set Hong Kong apart from China in idea and practice, through processes that disclosed British unilateralism and parochialism. Remarkably, similar processes are now taking place but in reverse, as heated debates about extradition and jurisdiction have arisen in Hong Kong’s postcolonial reassimilation into mainland China.
