One country, two systems
In accordance with the One country, two systems policy, the economies of the former British colony of Hong Kong and Portuguese colony of Macau are separate from the rest of China and each other. Both Hong Kong and Macau are free to conduct and engage in economic negotiations with foreign countries, as well as participating as full members in various international economic organizations such as the World Customs Organization, the World Trade Organization and the Asia-Pacific Economic Cooperation forum, often under the names "Hong Kong, China" and "Macau, China".
