Quick Summary

The British Supplementary Treaty of the Bogue, signed in 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. The treaty was part of a series of "unequal treaties" where China was compelled to cede territorial and sovereignty rights to imperialist powers.12
