Was more talking about exportation of Jl-10 with russian engines. That jet is competing with Yakovlev Yak-130 more or less. Anyway, Russia will probably say yes for that.Of course Russia has allowed the engine to be exported to China, and now Russia is subject to severe economic sanctions and relies heavily on trade with China.
Now that Sino-Russian relations are so important, it can be joked that Putin will shoot any officials who hinder this deal.
