Malaysia have MiG-29’s. Vietnam have MiG-29’s. The Kim’s have MiG-29’s. The Chinese have Su-27’s aka J-11’s. Both planes are very similar of course but I like the aerodynamics of the Su way better than MiG.
One small correction. Vietnam never operated Mig-29. The do however operate Su-30s and Su-27s. And they planes are not at all similar.
