Mongol khanates (Golden Horde, Chagatai Khanate, Ilkhanate) was achieved around 1304 after the Kaidu–Kublai war that had lasted for more than 30 years and caused the permanent division of the Mongol Empire. Temür Khan was recognized as their nominal suzerain. While the peace itself was short-lived and the war soon resumed, this established the nominal supremacy of the Yuan dynasty over the western khanates that lasted for a few decades. Foreign Policy: Southeast Asia Soon after his enthronement in 1294, Temür called off all preparations for further expansions to Japan and the Đại Việt, whose new ruler ignored his grandfather's envoy in 1291. Temür sent his messengers to Japan and Champa to demand submissions. Champa accepted the terms, but the Kamakura shogunate declined, and the Japanese Wokou attacked Ningbo late in his reign. The rulers of Đại Việt, Burma, and Sukhotai visited Khanbaliq to greet him as their overlord in 1295, 1297, and 1300. In response to the visit from the prince of Burma, he aborted the Burmese campaign and said to all his ministers: "They are our friendly subjects. Do not attack their people". Temür also released envoys of Đại Việt to show his goodwill, and the Tran court began to send tributary missions. But Temür's government had to quell rebellions in the southwestern mountainous area, led by tribal chieftains like Song Longji and female leader Shejie in 1296. It took long months for the generals Liu Shen and Liu Guojie to suppress these rebellions. By the request of the Burmese prince, Tribhuvanaditya, Temür dispatched a detachment of the Yuan army to Burma in 1297. They successfully repelled the Shans from Myanmar. Temür also received envoys from Siam and Cambodia. He dispatched Zhou Daguan to Khmer Cambodia in 1296, and Zhou wrote an account about his journey. In 1299 Athinkaya murdered his brother Tribhuvanaditya, who submitted to Temür in 1297. In 1300, a punitive expedition was launched as the Second Mongol invasion of Burma for dethroning Temür's protectorate, Tribhuvanaditya. The Shan warlords of Babai-Xifu, who were quarreling over the royal succession of Pagan, also raided the Yuan realms. Temür sent his Yunnan-based force in turn to halt the advance of Babaixifu (Lanna Kingdom of Chiangmai) in 1301–1303. Although those campaigns were fruitless, Athinkaya and the Shan lords offered their submission. The costly expedition spurred rebellions of a Yunnan official, Song Longji, and the Gold-Tooths (ancestors of the Dai people)
