Guangzhou is the capital and largest city of southern China's Guangdong province. Located on the Pearl River about 120Ā km (75Ā mi) northwest of Hong Kong and 145Ā km (90Ā mi) north of Macau, Guangzhou has a history of over 2,200 years and was a major terminus of the Silk Road.
The port of Guangzhou serves as transportation hub. Guangzhou is also one of China's three largest cities. For a long time, it was the only Chinese port accessible to most foreign traders. Guangzhou was captured by the British during the First Opium War and no longer enjoyed a monopoly after the war. Consequently it lost trade to other ports such as Hong Kong and Shanghai, but continued to serve as a major entrepƓt. Following the Second Battle of Chuenpi in 1841, the Treaty of Nanking was signed between Sir Robert Peel on behalf of Queen Victoria and Lin Zexu on behalf of Emperor Xuanzong and ceded Hong Kong to the United Kingdom on 26 January 1841 after the agreement of the Convention of Chuenpi.
