The Embassy of China in London is the diplomatic mission of China in the United Kingdom. Established in 1877 as the Chinese Legation, the London mission was China's first permanent overseas diplomatic mission. It has served as the diplomatic mission of the Manchu Qing Empire, Republic of China and (since 1950) the People's Republic of China. It was the location of the Qing Empire's detention of Sun Yat-sen, an important episode in the Chinese revolution of 1911. It remains today the focal point for events relating to China held in the United Kingdom, including celebrations in 2012 to commemorate 40 years of diplomatic relations between the UK and the People's Republic of China.
