Why Which conflict eventually led to Britain and other European nations became the major economic powers in china?

The Opium Wars, particularly the First Opium War (1839-1842), were pivotal in establishing British and other European economic dominance in China. Britain's trade of opium in exchange for tea and other goods led to significant conflicts, culminating in China's defeat. The resulting treaties, such as the Treaty of Nanking, forced China to cede territory, open ports to foreign trade, and grant extraterritorial rights to Europeans, thereby integrating China into the global economy under European terms and solidifying their economic power in the region.
