Trần Nhân Tông
The Yuan dynasty was unable to militarily defeat the Vietnamese and the Cham. Kublai was angry over the Yuan defeats in Đại Việt, banished prince Toghon to Yangzhou and wanted to launch another invasion, but was persuaded in 1291 to send the Minister of Rites Zhang Lidao to induce Trần Nhân Tông to come to China. The Yuan mission arrived in Vietnamese capital on 18 March 1292 and stayed in a guesthouse, where the king made a protocol with Zhang. Trần Nhân Tông sent a mission with a memorial to return with Zhang Lidao to China. In memorial, Trần Nhân Tông explained his inability to visit China. The detail said among ten Vietnamese envoys to Dadu, six or seven of them died on the way. He wrote a letter to Kublai Khan describing the death and destruction the Mongol armies wrought on Dai Viet, vividly recounting the brutality of the soldiers, and the desecration of sacred Buddhist sites. Instead of going to Dadu personally by himself, the Vietnamese king sent a gold statue to Yuan court. Another Yuan mission was sent in September 1292. As late as 1293, Kublai Khan planned a fourth military campaign to install Trần Ích Tắc as the King of Đại Việt, but the plans for the campaign were halted when Kublai Khan died in early 1294. The new Yuan emperor, Temür Khan announced that the war with Đại Việt was over, and he sent a mission to Đại Việt to restore friendly relations between two countries.
