The Treaty of Livadia was an unequal treaty between the Russian Empire and the Chinese Qing dynasty signed in Livadiya, Crimea, on 2 October 1879, wherein Russia agreed to return a portion of the lands it had occupied in Xinjiang during the Dungan Revolt of 1862–1877. Even though Qing forces had reconquered the area, the resulting treaty was extremely unfavorable to China. As a result, the Qing government refused to ratify it and the emissary who made the negotiations was sentenced to death. Seventeen months later, the two nations signed the Treaty of Saint Petersburg, which apart from territorial matters, largely had the same terms as the Treaty of Livadia.

Unequal treaties refer to a series of treaties signed during the 19th and early 20th centuries, between China and various foreign powers. The agreements, often reached after a military defeat or a threat of military invasion, contained one-sided terms, requiring China to cede land, pay reparations, open treaty ports, give up tariff autonomy, legalise opium import, and grant extraterritorial privileges to foreign citizens.
