Ming tributary trade system

Timeline

1. 1567–1582Yuegang, Zhangzhou · FujianThe Longqing opening permitted limited private maritime trade at ports such as Yuegang, but tribute envoys and tallied trade were still regarded by the court as the orthodox form of foreign relations, creating an institutional pattern of parallel maritime and tribute trade.
2. 1583–1588Beijing · North ChinaDuring the Wanli reign, the Ministry of Rites, the Court of State Ceremonial, and the maritime trade offices jointly received tribute envoys from Korea, Ryukyu, Annam, and elsewhere; investiture, reciprocal gifts, and verification of tallies formed the core procedures of tributary trade, sustaining the Ming-centered investiture network of East Asia.
3. 1589–1590Fujian coast · FujianOn the eve of Toyotomi Hideyoshi's invasion of Korea, wokou raids and smuggling rose along the southeast coast; while maintaining the tribute channels, the court intensified inspection of private maritime trade and tribute ships, sharpening the tension between the tributary system and the maritime ban.
