while genghis khan was conquering transoxania and persia, several chinese who were familiar with gunpowder were serving in genghis's army. "whole regiments" entirely made out of chinese were used by the mongols to command bomb hurling trebuchets during the invasion of iran. historians have suggested that the mongol invasion had brought chinese gunpowder weapons to central asia. one of these was the huochong, a chinese mortar. books written around the area afterward depicted gunpowder weapons which resembled those of china.

history of iran
power struggles among various mongol factions in tibet and amdo led to a period alternating between the supremacy of the dalai lama (nominally) and mongol overlords. in 1642 the fifth dalai lama received both spiritual and temporal authority from the mongol king, güshi khan. this allowed the gelugpa buddhist sect and the dalai lama to gain enough power to last til the present day. the mongol king also gave portions of eastern tiber (kham) back to the tibetans; however amdo remained under mongol control.
