All captive Bactrians outside China are domesticated. Beijing Zoo does yet keep wild Bactrians and the Mongolia/China Gobi project maintains a small semi captive herd in the Lop Nur reserve.
Iran is in a different zoogeographical zone to China/Mongolia. No Bactrian camels ever ranged inside Iran, but the Elbruz and Himalayas put paid to that movement due south. In their Central Asian heartland they range in the territory of both kiangs and Mongolian wild ass (note the difference to Mongolian wild horse ...).
