The best description of the outcome of the Opium Wars is: The Qing Dynasty was forced to enter an unequal trading relationship that benefited Europeans.
The Opium Wars (1839–1842 and 1856–1860) resulted in the Treaty of Nanking and subsequent treaties, which imposed severe concessions on China, including the cession of Hong Kong to Britain, the opening of multiple ports to foreign trade, and extraterritorial rights for foreigners. This ultimately established a system of unequal treaties that normalized foreign exploitation of Chinese trade and sovereignty.
