The agriculture sector is almost non-existent in Hong Kong which has to import 80% of its food supplying. Hong Kong does not possess any natural resources and depends on its raw materials and energy imports. The manufacturing industry contributes to 5% of the GDP and its leading sectors are textile, clothing and electrical components. Services sector, especially financial services, is the heart of the economic activity: Hong Kong is the second largest Asian money market and the world's fifth banking centre. Furthermore, the island is the second tourist destination in Asia, with 21 million visitors in 2004.
A free trade agreement entered into force on the 1st of January 2004 between Hong Kong and mainland China, which reinforces mainland's influence concerning external trade. One third of mainland's external trade goes through Hong Kong, and re exports account for 92% of Hong Kong total exports. Its three top export partners are mainland China, Japan and Taiwan. The region mainly imports machinery, vehicles, manufactured products and chemicals.
