I don't think China is going to attack Taiwan, no matter how many questions are raised about China and Taiwan war. Various media circles sometimes create such hype. Today, China is working hard to expand its soft power globally through economic aid, cooperation and education, as well as presenting itself as a peaceful country and a generous friend to every nation. However, its potential incursion into Taiwan could damage China's reputation and disrupt its economic and political relations with other countries. Hopefully there is no current or future war between the two sides.
I have talked but this topic with someone who is actually from Taiwan, he explained to me that China would like to annex Taiwan for political and historical reasons, rather than economical reasons. It seems that in the Chinese culture the true leader of the nation (formerly the emperor) would be only considered to have the supreme mandate given to him from heaven if he had political authority over all provinces of China, including Taiwan.
So historically, however the president of China is, he cannot forfeit Taiwan or give up on apparent efforts to reconquer it, because it would translate into serious damages to his reputation and power.
As far as I understand, the president of China who manages to successfully take Taiwan back would be remember for the rest of history as the actual leader who had the mandate given from heaven.
