All this is a bit off topic thread, but I'm more than happy to continue the discussion in the appropriate thread.
But with that said between the pandemic, issues with the MAX, and delays to the 777x program, GE is burning through gobs of cash. They are in desperate need of cash flow to recover from one of the most disastrous periods in history, and that money won't be sufficient from local and European demand (case and point the airline I worked for has been in talks with Boeing and GE to delay their 777 and Dreamliner orders). Despite how many MAXs United pledges to buy, its pennies compared to the commercial airline market in China. The lobbying arm of GE cannot afford to allow the federal government to place further trade embargoes on Chinese business, and similarly the US Commerce Department cannot afford to let one of it's leading engineering companies suffer much longer and risk going under.
Based on operational manuals from my Airbus differences course (so that I could fly the A320ceo and neo), the fuel burn difference according between the IAE engine (the airline I worked for didn't use CFMs) and the LEAP is absolutely massive. We'd burn like 2.2 tons per hour on the IAE, but the manuals say that number goes down to ~1.8t at 30000ft. Two of my best friends work for another airline recently had a go at the MAX, and they told me they were burning ~1.6t at 40000ft with the LEAP. While I won't say the IAE/CFM engines are uneconomic or unprofitable, the margins and operational savings between engine generations is just mind blowing-ly massive - you won't lose tons of money operating an engine from the CFM56 generation, you're saving a helluva lot more from the LEAP.
I'm sure if push comes to shove in the trade war that a more commercially friendly variant of the WS-20 can be spun off as a stop gap for the CJ-1000 and provide comparable performance to the CFM56.... but realistically I just can't see how the Biden Administration can afford the risk of killing off a company that's crucial to national security despite how sour Sino-American relations are currently. All signs point to the CJ-1000 becoming a reality, GE and the US best milk the cow while they still can... especially when there aren't a whole lot of alternate sources of funding/income.
