According to archaeological studies initiated in the 1920s, human activity on Hong Kong dates back over five millennia. Excavated neolithic artifacts suggest an influence from northern Chinese stone-age cultures. The territory was settled by Han Chinese during the seventh century, A.D., evidenced by the discovery of an ancient tomb at Lei Cheung Uk in Kowloon. The first major migration from northern China to Hong Kong occurred during the Sung Dynasty (960-1279). Hong Kong was ceded to Britain in 1842 under the Treaty of Nanking. Britain was granted a perpetual lease on the Kowloon Peninsula under the 1860 Convention of Beijing, which formally ended hostilities in the Second Opium War (1856-58). The United Kingdom, concerned that Hong Kong could not be defended unless surrounding areas also were under British control, executed a 99-year lease of the New Territories in 1898, significantly expanding the size of the Hong Kong colony.
In the late 19th century and early 20th centuries, Hong Kong developed as a warehousing and distribution center for U.K. trade with southern China. After the end of World War II and the communist takeover of Mainland China in 1949, hundreds of thousands of people fled from China to Hong Kong. Hong Kong became an economic success and a manufacturing, commercial, finance, and tourism center. High life expectancy, literacy, per capita income, and other socioeconomic measures attest to Hong Kong's achievements over the last five decades. Natural resources: Outstanding deepwater harbor. Industry: Textiles, clothing, electronics, plastics, toys, watches and clocks. Exports: Clothing, electronics, textiles, watches, clocks and office machinery.

On the international front, Hong Kong is a separate and active member of the World Trade Organization (WTO) and the Asia Pacific Economic Cooperation (APEC) forum, where it is an articulate and effective champion of free markets and the reduction of trade barriers. Hong Kong residents across the political spectrum supported China's accession to the WTO, believing this would open new opportunities on the Mainland for local firms and stabilize relations between Hong Kong's two most important trade and investment partners, the United States and China. Hong Kong's foreign relations and defense are the responsibility of China. Hong Kong is an independent customs territory and economic entity separate from the rest of China and is able to enter into international agreements on its own behalf in commercial and economic matters. Hong Kong, independently of China, participates as a full member of numerous international economic organizations including the World Trade Organization, the Asia Pacific Economic Cooperation forum and the Financial Action Task Force.
