Which countries signed the Treaties of Tianjin in 1858?

The Treaties of Tianjin were signed in June 1858 between the Qing dynasty of China and four foreign powers: Great Britain, France, the United States, and Russia.1

These agreements were negotiated following the military successes of British and French forces during the second Opium War. The treaties granted foreign powers significant concessions, including the right to station diplomats in Beijing, the opening of additional treaty ports for trade, the legalization of opium importation, and freedom of movement for Christian missionaries.12
