The Hong Kong Special Administrative Region (HKSAR) of the People's Republic of China is firmly committed to an open market policy. This policy applies to all trade, as well as to all investments in the HKSAR.

Hong Kong has become a Special Administrative Region of the People's Republic of China since 1 July 1997. The "One Country, Two Systems" principle provides the HKSAR with a high degree of autonomy in economic, trade, financial and monetary matters. This is guaranteed by the Basic Law, which ensures that the important elements making Hong Kong an international financial centre are extended well beyond 1997. These include continuation of the capitalist economic and trade systems, free movement of goods and capital, free port and separate customs territory. Tariff preferences and other similar arrangements obtained or made by the HKSAR are enjoyed exclusively by the HKSAR. The Basic Law also provides that the HKSAR may participate in relevant international organisations and international trade agreements using the name "Hong Kong, China".

In 1986, Hong Kong became a separate contracting party to the General Agreement on Tariffs and Trade (GATT). Upon the establishment of the World Trade Organization (WTO) on 1 January 1995, Hong Kong became one of its founding members. Hong Kong also became a member of the Customs Cooperation Council (subsequently renamed the World Customs Organization) in 1987 and the Asia-Pacific Economic Cooperation in 1991. The status of the HKSAR in these and other international organisations remains unchanged except that our participation is now under the name "Hong Kong, China".


The Hong Kong economy is externally oriented and highly dependent on trade with the rest of the world. In 2021, the value of Hong Kong's total merchandise trade reached HK$10,268.4 billion (US$1,320.9 billion), or around 358% of the Gross Domestic Product (GDP) in that year. The value of imports amounted to HK$5,307.8 billion (US$682.8 billion) or around 185% of GDP. The value of exports was HK$4,960.7 billion (US$638.1 billion) or around 173% of GDP. Hong Kong was the world's 6th largest trading entity in goods in 2021 (Note 1) - 7th largest importer and 6th largest exporter.

The services sector is very important to the Hong Kong economy. It contributed to 93% of the GDP accounted for 89% of the total employment in 2020. As for Hong Kong's trade in services, total trade in services amounted to HK$945.2 billion (US$121.9 billion) or about 35% of GDP in 2020. In 2021, Hong Kong ranked 20th in the world league of commercial services trading entities - 23rd largest importer and 21st largest exporter.
