Sino-British supplementary treaty
Quick Summary
The British Supplementary Treaty of the Bogue, signed on October 8, 1843, supplemented the Treaty of Nanjing which ended the first Opium War. This treaty granted British citizens in China extraterritorial rights, meaning they were subject to their own consuls and not Chinese law. It also included a most-favoured-nation clause, ensuring Britain received any rights China granted to other foreign powers. This was part of a series of "unequal treaties" that China was compelled to sign with imperialist powers during the 19th and early 20th centuries, resulting in concessions of territory and sovereignty.12
