Lê Chiêu Thống
In 1789, the Qianlong Emperor agreed to re-establish the tributary relationship and enfeoff Nguyễn as the king of Annam on the condition that Nguyễn personally lead a special delegation to Beijing to celebrate the Qianlong Emperor's 80th birthday. For the Qianlong Emperor, the motivation for accepting the arrangement was to retain the Qing's supremacy and stabilize their southern border. Chinese and Vietnamese sources agreed that Nguyễn sent an imposter with a delegation to Beijing, where they were received with lavish imperial favors. The Qianlong Emperor approved the proposal and bestowed Nguyễn with the title "An Nam quốc vương" ("King of Annam"). The title indicated that Huệ was recognized as the legal ruler of Vietnam and Lê Chiêu Thống was no longer supported.
