British Concession of Jiujiang

Established in 1861 in the aftermath of the Second Opium War as a result of the Treaty of Tientsin, the concession remained under British control until 1929, when it was ceded to the Republic of China under the terms of the Chen-O'Malley Agreement.

[1][2] In 1860, the Second Opium War ended in a British victory, and the government of the Qing dynasty ratified the Treaty of Tientsin during the Convention of Peking, which granted the United Kingdom a foreign concession in a Chinese port city.

Beginning in January 1861, British diplomat Harry Parkes travelled through the Yangtze river onboard a Royal Navy vessel to investigate local conditions and select the site of the new concession.

[4] On 27 March 1862, the British concessional authorities resurveyed the boundaries of the concession, which led to a minor confrontation with a group of local residents.

However, the British continued to retain de jure control over the concession until 1929, when under the terms of the Chen-O'Malley Agreement it was officially ceded to the Republic of China.
