COMAC (Shanghai Pudong) is restructuring its supply chains to mitigate geopolitical risks following the temporary suspension of CFM International LEAP-1C engine exports mid-2025. The manufacturer delivered fifteen C919 jets in 2025. That is just over a half of the revised target of 28, and significantly below the initial target of 75.

Production continues to face internal manpower shortages, alongside delays from foreign suppliers. To reduce reliance on Western core systems, the Aero Engine Corporation of China (AECC) is accelerating development of the indigenous CJ‑1000A engine, which is approaching final certification.
