The property rights of the entire C919 aircraft belong to COMAC. The development was centered on COMAC’s team. Key links such as aircraft design, final assembly, flight testing, and sales are all in the hands of COMAC. inside. COMAC is choosing which engine, which avionics core processing system, and which materials to use. "Chinese design, system integration, global bidding, and gradually improving localization", COMAC's idea of ??developing aircraft clearly shows that the C919 large passenger aircraft is indeed "Made in China" and it embodies the will of the Chinese people. .

Therefore, it would be unobjective to say that C919 is purely domestically produced, but it would be even more biased to say that it is an assembled product - it is more appropriate that C919 is a product of cooperation between Chinese and foreign manufacturers.
