As elsewhere in Asia, in China the Portuguese were the pioneers, establishing a foothold at Macao (Aomen in pinyin), from which they monopolized foreign trade at the Chinese port of Guangzhou (Canton). Soon the Spanish arrived, followed by the British and the French.

Trade between China and the West was carried on in the guise of tribute: foreigners were obliged to follow the elaborate, centuries-old ritual imposed on envoys from China's tributary states. There was no conception at the imperial court that the Europeans would expect or deserve to be treated as cultural or political equals. The sole exception was Russia, the most powerful inland neighbor.

The Manchus were sensitive to the need for security along the northern land frontier and therefore were prepared to be realistic in dealing with Russia. The Treaty of Nerchinsk (1689) with the Russians, drafted to bring to an end a series of border incidents and to establish a border between Siberia and Manchuria (northeast China) along the Heilong Jiang (Amur River), was China's first bilateral agreement with a European power. In 1727 the Treaty of Kiakhta delimited the remainder of the eastern portion of the SinoRussian border. Western diplomatic efforts to expand trade on equal terms were rebuffed, the official Chinese assumption being that the empire was not in need of foreign--and thus inferior--products. Despite this attitude, trade flourished, even though after 1760 all foreign trade was confined to Guangzhou, where the foreign traders had to limit their dealings to a dozen officially licensed Chinese merchant firms.

Trade was not the sole basis of contact with the West. Since the thirteenth century, Roman Catholic missionaries had been attempting to establish their church in China. Although by 1800 only a few hundred thousand Chinese had been converted, the missionaries--mostly Jesuits--contributed greatly to Chinese knowledge in such fields as cannon casting, calendar making, geography, mathematics, cartography, music, art, and architecture. The Jesuits were especially adept at fitting Christianity into a Chinese framework and were condemned by a papal decision in 1704 for having tolerated the continuance of Confucian ancestor rites among Christian converts. The papal decision quickly weakened the Christian movement, which it proscribed as heterodox and disloyal.
