But you do need a licence to produce new engines.

The Russians probably didn't expect China to be able to reverse engineer the AL-31F variants, so there probably wasn't any discussion on whether China is allowed to produce new engines "based on" AL-31F. Same thing happened with the flankers.

I doubt that's the case:

Russia cancels sale of Su-33 fighters to China to prevent their pirate copies 0.03.2009 :
english.pravda.ru/russia/economics/10-03-2009/107208-russia_china-0/

These are some of the info i found with a quick google search, no its no secret china's RE capabilities. I Also read somewhere that CHINA had ordered about 200 AL-31F engines, but suddenly canceled the order at about 100. I don't know how many prior order had been ...but I'm guessing not enough to cover its fleet needs

Exactly. CAC can divide an AF-31FN into two halves, then complete each with new components. Both "new" engines would still technically be legally brought.

But they're not gonna do that, because it confers no advantage whatsoever. It won't stop the Russians from complaining, if they so wish to, and thus it makes no sense to limit yourself with such constraints.

As for Roger, he gets a little excited sometimes.

Has i said this just random info from a google search, the poit i was making is tha: CHINA can RE almost anything they got thiers hands on.
 and the Russians know that...
I'm not saying thats wrong or proof a of "copy-paste"industry.... in fact RE can be a extremely complicated matter, and for that only a proof of this guys advanced tech...

Going on topic: does the WS-10a or some know variant at the moment can supercruise???

2011年1月30日上午10点得到一个内部消息，一航的领导新春团拜会讲话，是关于J20飞机的问题，也就是大家的疑问：发动机过关吗？现在非常激动的告诉大家：过关了！WS-15发动机。测试结果不加力16.3吨，加力18.7吨。第一次生产实验机两台，一台在测试台平稳运行3600小时了，一台反复启动450次，一切正常；J20的机器是第二批次的四台之一。下一步马上量产了。

An internal news on January 30, 2011, general leadership spring tuanbaihui speech is about J20 problem, which is everyone's questions: engine: clearance? now very excited to tell you: crossing the!WS-15 engine. Test results are not empowered 16.3 tons, Afterburner 18.7 tons. Production machine for the first time two, one in the test run smoothly 3,600 hours, over 450 boots, everything is normal; J20 machines is one of the second instalment of the four. Next production quantities at once.

I think the fanboy who made up the story didn't consider over the details like which warehouse Chinese would use to store the engines if they were going to mass produced WS-15, since J-20 is far away from the phase of mass production yet.

Wow, such long article, I use to see such "official" articles in chinese forum, I usually don't understand.
for this article, I think Liming factory cooperate with GE develop new technology for some parts of GE-90 engine, both side used each other, but GE still control their own core technology, never share to Liming.

I think it is an official website.

The article says GE and Liming developed a new method to manufacture the part, not to design it.

What I want to suggest is, if Liming was a bad-managed factory as some members here think, how on earth would GE allow Liming to manufacture parts for its engines?
