AL-31FN Series 3 engine count. I'll do it with photographic evidence.
53 engines used up for J-10B production.
49 engines used up for J-10C production.
16 engines used for J-20 prototypes.

And lastly, we have this picture of three LRIP J-20s together.
6 engines.
124 engines used up.
This
surpasses the 123 AL-31FN Series 3 engines purchased in 2011 for $500 million. There should be no engines left. But where is the Russian/Chinese announcement of additional engine orders?
Moreover, I would like to point out that we had news regarding the J-10A engine
many months prior to initial production in 2002. I'll provide two examples below. Note the dates of these reports.

China to buy Russian engines for F-10 fighters June 15, 2001 PARIS,
Jun 14, 2001 (Itar-Tass via COMTEX) - - The command of the Chinese army decided to equip its F-10 fighter planes with the Russian AL-31FN engines, a member of the Chinese delegation at the international airshow in Le Bourget told Tass on Thursday. He said the Chinese army is to receive over 300 such planes in the coming ten years. The serial production of the fighters is to begin in 2003. However Russia will supply several dozen of the engines in the coming two years.

<Kanwa News
Sept 10th 2001> Kanwa learned that Chinese J10A (F10A) fighters would be mass-produced starting from next year. J10A will be installed with AL31FN turbofan engine developed by Russia's SALUT. The source revealed that under the Russia-China mutual agreement, in Phase One, 54 AL31FN engines would be turned over to China by the end of this year. Consequently, there will be 300 same type of engines turned over to China. This plan is in effect till after 2003. The movement indicates that the first batch of mass produced J10A will be numbered around 50. The production will start from next year.
The above news has been confirmed by Chengdu No.132 factory, source from this factory said that they are working hard for the "Type" plane (Xing Hao Ji) in the final phase.....! <Kanwa digest news>

J-10A production began in 2002. And we got the news above before the days of social media and widespread news on the internet.
On the other hand, J-20 LRIP already began when 2101 appeared in December 2015. It is now October 2016 -- at least 10 months later. Where are the reports of an engine deal with Russia? According to rumors, J-20 is likely to enter service with the PLAAF at the end of 2016. We are also getting reports that J-20 will be showing up at Zhuhai Airshow next month. The plane is now being publicly unveiled. How can there be no news regarding a Russian engine deal at such a late stage in the J-20's development if the J-20 is indeed using the AL-31FN Series 3? There is nothing top secret about the AL-31FN Series 3 at this point. Why keep something as mundane as an engine deal secret?
