See that Masalov is the same guy who made the speech for Xu and he claims Salut has delivered around 1000 Al-31 deliveries to China including engines for J-11s/Su-27
"Masalov further said that the grand total of Salut-made AL-31 series engines in China “is nearing one thousand units.” To serve them, Salut has established partnerships with Limin Corp. and Tyan Li company in Chengdu
on deliveries and manufacturing of spare parts for both the AL-31F and the AL-31FN. Russia has also agreed to provide all necessary maintenance and repair documentation to the Chinese partners. Salut faces many issues pertaining to ramping up production to fill these big Chinese orders, Masalov said. This year the company must increase its production output by 30 to 40 percent to fulfill the Chinese contracts. “Certainly there is some pressure on us, with bottlenecks being metal and vendor items,” Masalov said.
Meanwhile, Salut is negotiating the sale of another 40 AL-31FM1 engines to the Russian Air Force for the Su-27SM upgrade. Twelve have already been ordered. Talks to supply AL-31FM2 versions for the Su-34 continue, Masalov said.
