I highly doubt that since China makes its own varient of Russian weapons, and aircraft. Russia never supplies China with actual aircraft, even today. China is just given the blueprints basicly, and they make the Russian varient sutable for their pilots, and make some modifications. If you look at a Chinese MiG and a Russian MiG, they will be very different in some aspects like engines, control positioning and wiring from time to time (This can be said for the Chinese MiG-21).

Same with weapons, the Chinese Ak is smaller than the Russian Ak, and in some instances are completely different on the inside, but look the same on the outside.
