paragraph_text: Attempts to attack the Ming dynasty
  
  In 1368, the Yuan dynasty collapsed and was succeeded by the Ming dynasty. The Ming dynasty during the reigns of its founder, the Hongwu Emperor, and his son, the Yongle Emperor, produced tributary states of many Central Asian countries. In 1394, the Hongwu Emperor's ambassadors eventually presented Timur with a letter addressing him as a subject. Timur had the ambassadors Fu An, Guo Ji, and Liu Wei detained. Neither the Hongwu Emperor's next ambassador, Chen Dewen (1397), nor the delegation announcing the accession of the Yongle Emperor fared any better.
  
  Timur eventually planned to invade China. To this end, Timur made an alliance with surviving Mongol tribes in the Mongolian Plateau and prepared all the way to Bukhara. Engke Khan sent his grandson Öljei Temür Khan, also known as "Buyanshir Khan" after he converted to Islam while at the court of Timur in Samarkand.
