[6] Between November 12, 1933, and April 6, 1934, he was selected the prime minister of the short-lived Turkic Islamic Republic of East Turkestan (TIRET) in Kashgar.

Khoja Niyaz, the leader of Kumul Rebellion in 1931, was invited by Sabit Damulla to Kashgar to assume presidency of the self- proclaimed Republic.

Contemporary sources say that Abdulbaki was captured by Khoja Niyaz near Aksu in late April 1934, then delivered to Governor Sheng Shicai.

Previously, in early April 1934, being in his native village of Artush Sabit Damulla rejected several urgent offers from Ma Zhongying to return to Kashgar and form a military alliance against advancing common enemies: Soviet backed Governor Sheng Shicai and Khoja Niyaz.

Fellow Chinese Muslims such as Kuomintang officer Liu Bin-Di provided him with the Quran and other Arabic and Chinese Islamic texts to be translated into Uyghur (The establishment of Islam in China in 650 stemmed from the delivery of a Quran by Caliph Usman to Tang Emperor Gaozong in 650 through Envoy Sa'ad ibn Abi Waqqas, one of Muhammad's first companions).
