Nemo also brings up a good point, AWACS is essential to air operation. If China's carriers can reduce Taiwan AWACS operation and enhance its own AWACS safety than PLAAF/PLAN airarm will have significant intel advantage over its adversary.
To ZYUN: its never too late, Taiwan is a prize china wants. The Carrier Project, the modernization of Air Force and Marines are all toward that end. To gain superiority over Taiwan Strait. Unlike USA carrier program, china doesn't want power projection over the world it just want what it consider rightfully theirs. When PLAN carriers are ready and Taiwan manage to declare independance and join UN China will invade. PLAN carriers will be on the forefront no doubt about it.
