Canton System
The Canton System (1757–1842; Chinese: 一口通商; pinyin: Yīkǒu tōngshāng; Jyutping: jat1 hau2 tung1 soeng1, lit. "Single [port] trading relations") served as a means for Qing China to control trade with the West within its own country by focusing all trade on the southern port of Canton (now Guangzhou).
