Hi,
The problem is that China is spread too thin. If it had 400 to 500 su 30' s or j 11' s and another 400 to 500 J10's, things would be very interesting.
China can hardly deploy one third of its frontline aircraft, the rest will be covering its flanks. For the Taiwanese they know that they would only have a small window of opportunity to inflict as much damage on the Chinese aircraft before it's airfields are targeted by the ground strike missiles.
Truthfully--- China is in a woeful position. With India on one side, Taiwan, Japan, Vietnam. China is not the monster that people claim it to be.
The trick that the Chinese played on the Russians by not fulfilling the order of the aircraft has backfired for China. Power play and power positioning did not wait for China to achieve its military acquisitions. Countries like Philippines and Vietnam are not afraid to back down from China at this time. It is only the u s holding them back, because they don't want another conflict at this time.
Irfan,
The comment about the blk 52 f 16 was just meant to show that even Pakistani frontline is more advanced than anything that China has and all this hype that China has created, they are still woefully equipped.
