The Golden Horde invaded the Ilkhanate under Abu Sa'id in 1318, 1324, and 1335. Öz Beg's ally Al-Nasir refused to attack Abu Sa'id because the Ilkhan and the Mamluk Sultan signed a peace treaty in 1323. In 1326 Öz Beg reopened friendly relations with the Yuan dynasty and began to send tributes thereafter. From 1339 he received annually 24,000 ding in Yuan paper currency from the Jochid appanages in China. When the Ilkhanate collapsed after Abu Sa'id's death, its senior-beys approached Öz Beg in their desperation to find a leader, but the latter declined after consulting with his senior emir, Qutluq Timür.
