RUSSIA WILL NEVER SELL FIFTH GEN. AIRCRAFTS TO CHINA AND ITS BCOZ.....
1.NO OFFENCE BUT CHINA DOES MAKE REVERSE ENGG. OF AIRCRAFTS
2.INDIA HAS 50% SHARE IN THE PROJECT. AND WE WILL NEVER AGREE TO SELL CHINA.
ALSO I DON'T THINK THAT RUSSIA WILL SELL THIS AIRCRAFT TO WEST EUROPEAN COUNTRIES BCOZ MANY OF THESE COUNTRIES ARE ALLIES OF USA. THERE IS A POSSIBILITY THAT USA CAN ACCESS THOSE PLANES. WE ALL KNOW THAT USA HAS 5TH GEN. FIGHTERS BUT EVERY PLANE HAS ITS SPECIAL TECHS. AND ADVANTAGES OVER OTHER PLANES.
If that's the case then Russia shouldn't sell this to anyone because there will always be a way for either USA or China to examine its capabilities.
