I really wished China had money for Mirage 2K in the 80s.
'历史没有如果‘Theres no if in history. But anyway, there's what IF when we combed history of the honeymoon era, there were chances PLAAF acquiring western planes, notably F14, F16-79 and M2K. But i'm glad PLAAF held on with domestic development which resulted in arguably best 4th gen heavy fighter (Sino-flanker), J10C developments which build up China's aviation industry that leads to development of J-20s and six gens today. Should PLAAF went with F14 and F16-79, China would be sanctioned by US, plagued with high maintenance cost of F14 and subpar performance of F16-79. And how far can you upgrade Mirage 2000 anyway?
Be glad that Su-27k and J-10 happened.
