Tensions between China and Taiwan can be more dangerous because of us support to taiwan

Taiwan is showing eye to China because China have clearly mentioned that they can do anything for their part, because China has said that Taiwan is a part of China.
After this statement from China their is tensions between China and Taiwan.

Taiwan war exercises can be work like a amber for China but war with Taiwan will not be easy for China even with large army in comparison of Taiwan army because Taiwan have good military and strategic relationships with us so if war happen in between these two countries than usa will give advance weapon support to taiwan which is a cause of worry for China.
Or if this war happen than their will be a unstable environment for all other countries in this Asia Pacific region.
