Treaty of Tientsin

The Treaties of Tianjin were signed in June 1858, ending the first part of the Second Opium War (1856-1860). France, Russia, and the United States were party. These treaties opened eleven more Chinese ports (see Treaty of Nanjing) to the foreigners, permitted foreign legations in Beijing, allow Christian missionary activity, and legalised the import of opium.

They were ratified by the Emperor of China in the Beijing Convention in 1860, after the end of the war.
