Question

Quizplus · Accepted Answer

The Treaty of Nanking (1842) required China to open up the four large cities of Guangzhou, Fuzhou, Xiamen, and Ningbo to foreign trade with low tariffs, allowing the British and other foreign powers to conduct unlimited trade. Although China was also required to cede Hong Kong to the British and pay an indemnity, these were not the most significant terms of the treaty. The British were not given oversight of all customs duties, only those collected on the opium trade.
