China has no reason nor any incentive to invade Taiwan. They are moving ahead with a strategy of overwhelming force and patience. In short China will simply continue to greatly expand its Navy and overall military size. It will do so until its so overwhelming that Taiwan will simply end up voting to join back with China as it will be in its own interest. China has no need to speed this process up and can simply do exactly what it is doing now.. and just watch how things will change in the next 5-10-15 years.
