Hong-wu: Year 35, Month 9, Day 7
3 Oct 1402
Envoys with proclamations of the Imperial accession and instructions were sent to the countries of Annam, Siam, Java, Ryukyu, Japan, Xi-yang, Samudera and Champa. The Emperor had previously issued instructions to the officials in the Ministry of Rites, saying: "During the reign of the Gao Emperor Tai-zu, all the fan countries sent envoys to the Court and they were all treated with sincerity. Those who came with local goods were allowed to trade and had things made easy for them. When there were people who did not know how to control their envy or offended against legal regulations, all were forgiven, as a way of cherishing those from distant lands. Now all in the four seas are one family. It is proper that we widely proclaim that there are no outsiders. All countries which wish to express sincerity by coming to offer tribute are to be allowed to do so. You should send instructions to these countries so that they are clearly aware of my will."
