 China was to grant the same privileges to the Kingdom of France as to Britain in the Treaty of Nanking and subsequent treaties.The privileges included the opening of five harbours to French merchants, extraterritorial privileges French citizens in China, a fixed tariff on Sino-French trade and the right of France to station consuls in China.Although French Prime Minister François Guizot had given Lagrené only a mandate to negotiate a commercial treaty with France, Lagrené decided that he wanted to enhance France's international prestige by securing a rescission of Yongzheng Emperor's prohibition of Christianity in China from 1724.
