There is simply no chance China would sleep walk pass this:

That was five years ago. The urgency for CJ1000A and CJ2000 comes directly from that.

Elements within Congress did indeed push to block the sale of LEAP turbofans to COMAC in 2020, but

.

The other thing to keep in mind is that LEAP turbofans are produced by a joint venture between General Electric and Safran.

So if Trump bars GE from further sales then he effectively hands the entire business to the French, unless he can somehow convince Paris to turn down billions of Yuans, if not billions of Euros in potential sales.

Not to speak ill of the CJ-1000A turbofan or the development path it has taken thus far, but foreign customers may insist on the employment of Western engines due to political pressure and/or regulatory gridlock for decades to come.

Why do u think they havent yet? is Leap engine from a French US company?
in Early 2020, US administration decided to block LEAP engine sales to COMAC

but in March, 2020 trump administration granted license to sell LEAP engines..

"I want China to buy our jet engines, the best in the World,” Trump tweeted on Feb. 18 2020. “I want to make it EASY to do business with the United States, not difficult. Everyone in my Administration is being so instructed, with no excuses...”

one interesting fact about LEAP-1C engine of C919

C919 used LEAP-1C variant. specifically developed for C919 and CFM purposely didn't include latest technology in this variant like CMC material and engine also lacks many of the improvements of the other LEAP models over concerns that the technology could stolen. and might be use in CJ-1000.. :D :D

That sounds more like a ploy to keep C919 less competitive with western planes rather than to prevent technology theft. They export A320neo and 737max, as many as China would buy, which comes fitted with LEAP-1A and LEAP-1B. If China wanted to look at something they can just take apart LEAP-1A.

i was about to say this..

Chinese airlines purchases tons of aircrafts with top Engines from GE/RR.. if they really want, they can strip one of Engines and send it to their laboratory. dead easy

btw, China mastered CMC material and next generation manufacturing process for Turbofan production.. CJ-1000/CJ-2000 will surprise aviation enthusiasts.

China needs around 8000 narrowbodies in the next two decades.

Boeing built 528 commercial jets in 2023. If COMAC takes the entire Chinese market, it needs to build 400 C919s a year. Not that far off from Boeing on one jet liner alone.

Foreign orders are basically surplus and, frankly, irrelevant though good to have. Just grabbing a chunk of the domestic market will automatically make COMAC massively successful.

That's a fair point.

However, considering the scale at which the Chinese automotive and shipbuilding industries grew in terms of production volume as they matured, it is likely COMAC will exceed Boeing in annual output in due time, assuming the market demand will be in place.

As far as I can tell, the allegations of the LEAP-1C's inferiority originated from dubious sources. Wikipedia had cited baseless speculation from a Forbes article, which never presented any actual evidence. If you have more reliable sources than these, I'd like to hear about them.

The allegations of the LEAP-1C's inferiority was previously refuted by taxiya in the C919 thread. But that was last year, so I don't know if there has been any new information since then.
