The greatest diplomatic highlights of the Ming period were the enormous maritime tributary missions and expeditions of the admiral Zheng He (1371-1433), a favored court eunuch of the Yongle Emperor (r. 1402-1424). Zheng He's missions docked at ports throughout much of the Asian world, including those in Borneo, the Malay state of the Malacca Sultanate, Sri Lanka, India, Persia, Arabia, and East Africa. Meanwhile, the Chinese under the Yongle Emperor invaded northern Vietnam in 1402, and remained there until 1428, when Lê Lợi led a successful native rebellion against the Chinese occupiers.
