Similar processes occurred in Xinjiang and the rest of Western China where the PRC quickly established control from the Second East Turkestan Republic that controlled northern Xinjiang and the Republic of China forces that controlled southern Xinjiang after the Qing Dynasty. The area was subject to a number of development schemes and, like Soviet Central Asia, one focus was on the growing of the cotton cash crop. These efforts were overseen by the Xinjiang Production and Construction Corps. The XPCC also encouraged Han Chinese to return to Xinjiang after many had migrated out during the Muslim revolts against the Qing Dynasty.
