One of historic features of Chinese law has been a coexistence of more legal regimes on Chinese territory. They were efficient an enforceable enough to maintain the role of law in that time society.
Preparing for return of Hong Kong and Macao to China in 1997 and 1999 respectively, the leaders of the PR of Chine exploited such historical experience. It was clear that implementation of law of the PR of China would be for international community hardly to accept.
Therefore a model "one country - two systems was created" to make possible for both territories to maintain, interpret and develop their own law in cohabitation with legal system of the PR of China. Some experience from twenty years of functioning of this mechanism is dealt with in the present article.
