In the 18th century foreign trade was restricted to Canton. In the 17th century, however, the Dutch traded to Formosa and Amoy, and the English to Amoy also. The Portuguese traded with Canton as early as 1517. For the early intercourse between Portugal and China see the introductory chapter in Donald Ferguson’s Letters from Portuguese Captives in Canton (Bombay, 1902).
