But the problem is C919 is using GE engine... Will USA embargo it? Or AVIC has prepare another non civilian version strapped with WS-20?

IMHO there is nothing wrong with comparisons between products from different mnfg or countries. In fact I think it should be encourage ... HOWEVER when one veers off from merely comparison based on technical merits etc and goes into the supposition or future prediction about 'I think my country's product A can kick your country's @$$ because we're richer than you, our engineers/scientists are smarter than yours etc etc' then it becomes very negative and unproductive.
I've seen this go BOTH ways so this is not anti/pro China or a anti/pro US statement.

I thought they were developing home made engines for C919.
CJ-1000 is an civilian engine that will probably have lots of higher hurdle to overcome like noise level control and long hour duration usage which will take longer to solve than the military WS-20 engines.
Since AEW C919 will be serving the military. Those extra requirement for civilian standard will be omitted.

If they aim the WS-20 or CJ-1000 as a CFM-56 equivalent (in terms of meeting both military and civilian aviation standards), in the long run the benefits will be enormous, as the large number of units demanded and in use will, in long run, drive down the unit cost per engine and maintenance. Think about the emission standards that'd restrict the choice of air corridors or airports, if and when WS-20 equipped C-919 and Y-20 need to deploy overseas, be it for humanitarian relief effort or joint exercise.
But given the generation gap of Chinese engines compare with the West, that's a really tall order of things.

WS20 & CJ1000 are different things. CJ1000 is LeapX equivalence.
If they ever put CJ1000 on Y20, might as well make it a stretched Y20 to fully exploit the power.

Interesting ...
most notable difference aside from the winglets is the size of the turbofans but I'm sure when WS20 goes into it the size will be fairly close to the P&W F-117.

Not Much Differences Between Y-9 and Upgraded Y-8
Nice, that's a 10x5x serial production of the new Y-9 aircraft a very modern platform and great addition to PLAAF, hope we see a squadron of them fully operational soon
The 30175 is the PLAAF KJ-200 unit
