UK returns Hong Kong to China

On July 1, 1997, the United Kingdom returned Hong Kong to China at the conclusion of a 99-year lease. The foundation for the transfer of power was set in December of 1984 when China and the UK signed the Sino-British Joint Declaration on Hong Kong. The Declaration affirmed the handover of Hong Kong along with governing principles. Most significantly, the Chinese agreed not to impose their socialist system on Hong Kong.
