When the Syrian Turkmen Assembly was founded on May 2013, becoming the successor organization of the Syrian Turkmen Platform, During his tenure, the Assembly's activities became more organized and visible. Under his leadership, the Assembly officially affiliated with the
Syrian Turkmen Brigades as its armed wing, declared the Syrian Turkmen flag as a national symbol, and pursued more coordinated efforts alongside the broader
opposition. The Assembly also developed closer ties with Turkey and the United States in the
war against the Islamic State, particularly along the
Azaz–
Jarabulus corridor, and was recognized by several international actors as part of the "moderate opposition." Mustafa received support from Turkey, as well as from Gulf states such as Saudi Arabia (prior to regional policy shifts) and
Qatar, and was viewed by the United States as a representative of moderate opposition factions. He led the Syrian Turkmen delegation during the 2016
Geneva III peace talks as an official component of the broader Syrian opposition. Following the
Syrian National Coalition’s expansion, the
Syrian Turkmen Assembly was granted membership, increasing Turkmen representation within the coalition. In May 2017, Mustafa was elected vice president of the Coalition under president
Riad Seif. Analysts have noted that Mustafa played a central role in aligning the SNC more closely with Turkish strategic interests. He later met with President
Ahmed al-Sharaa in Damascus on 19 March 2025 to discuss the political transition. ==References ==
