Foreign imperialism in China

During the 19th and 20th centuries, foreign powers practiced imperialism in China through the imposition of unequal treaties, opening of treaty ports, and establishment of foreign concessions and leased territories. Starting with the 1842 Treaty of Nanking following the Qing dynasty's defeat by Britain in the First Opium War, various foreign powers, including Britain, France, the United States, Russia, Germany, and Japan, forced China to concede sovereignty and in turn gained territorial, economic, and legal privileges from China.
