西突厥
In 651, the Western Turkic Khaganate prince Ashina Helu, who had sought and received protection from Emperor Taizong, broke away from Tang and defeated the Western Turkic Khaganate's Yipishekui Khan, taking over the Western Turkic Khaganate himself and no longer subordinate under Tang. In fall 651, Ashina Helu attacked Tang's Ting Prefecture (庭州, roughly Changji Hui Autonomous Prefecture, Xinjiang), and Emperor Gaozong responded by commissioning the generals Liang Jianfang () and Qibi Heli () to attack Ashina Helu. Liang and Qibi achieved some victories against Ashina Helu's general Zhuxie Guzhu (), but then withdrew without engaging Ashina Helu.
