That would cause a shift in the balance of power in East Asia, with China in the ascent. In a confrontation with Taiwan, China would appear to have at least six options. The only way to crush Taiwan decisively would be an invasion, but the risks of failure would be high. Cross-water attacks are the most difficult of surface operations. Suitable landing sites in Taiwan are few.
China lacks sufficient landing craft to carry the required force.
Nor does it have enough air transport to carry the military's three divisions of 10,000 paratroopers each. China could not provide adequate air cover for such an invasion attempt. Taiwan has plotted a layered defense, and Taiwanese pilots are considered better trained than the Chinese. At sea, China's navy would outnumber Taiwan's, but the Taiwanese ships have better weapons. Under the sea, China's submarines far outnumber those of Taiwan and would win most battles.
