Treaty of Peking between Qing government and Portugal

In order to levy a tax on opium after the Sino-French War (1883-85), the ruler of the Qing dynasty went to Portugal and signed an agreement in March, 1887. The agreement required Macao to cooperate with China to track down smugglers, admitting that Macao would continue to be occupied by Portugal.

According to the agreement, the Qing dynasty and Portugal also signed the Sino-Portuguese Treaty of Amity and Commerce in Beijing later that year (December 1, 1887.) It was also called the Treaty of Peking. The treaty included a total of 54 articles, stating 4 main points: 1-China should admit and accept the "perpetual occupation and government" of Macau by Portugal; 2-Portugal can send an envoy to Beijing and set consul in trade ports; 3-Portugal can exercise consular jurisdiction in China; 4-Portugal can enjoy the privileges of trading that other countries have acquired or will acquire from the Qing dynasty, and the Portuguese people have the right to live near trade ports, rent and buy land, build houses and set up churches.

In 1928, the Chinese government declared the Treaty of Peking to be invalid.
