Sell 'em all the carriers that they want to throw their money at. Taiwan is within shore range from China, so PLA carriers don't change the power equation in the least. Ground-based Chinese fighters can already reach Taiwan, after all.Silent subs, which the Chinese do NOT have, would be a development worth watching, as would be the construction of landing craft in large-enough numbers to support an invasion of the size required to make some level of credible challenge to Taiwan's forces.
And of course, the chinese still need to figure out a way to gain air superiority over Taiwan's F-16's, something that they are nowhere close to achieving.
Destroyers, cruisers, loud submarines, and carriers are mere targets if they don't have air superiority. That's a long 80+ miles across the Taiwan Straight in a slow landing craft if one can't neutralize the Taiwanese air force, helicopters, anti-ship missiles, and submarines...
And remember, Taiwan was the third partner developing the Israeli/South African nuclear bomb. Chiang Ki Shek's forces would not hesitate to go nuclear if they thought that they were about to lose their island. Kiss the ships in the Straight goodbye. Kiss the Three Gorges Dam goodbye. Kiss Beijing and Shanghai goodbye.
And then after that pounding, the Indian Army is going to reclaim its Kashmiri territory that China is still occupying, and India has about as many people as does China, in addition to a nuclear strategic force of comparable size.
Considering that China lost its last GROUND war to Vietnam in 1979, the thought of taking on first Taiwan and then later India probably does not please the leadership chain in Beijing in the least.
