Taiwan's newly acquired HIMARS and Abrams tanks would raise the costs of a Chinese amphibious landing, a defense analyst says.

Taiwan began its annual military drills on Wednesday with troops joined by the largest-ever mobilisation of reservists for 10 days of training aimed at defending against a Chinese invasion.

The risks China would face in invading Taiwan far outweigh any potential gains, Grazier said. China has many other military options at its disposal that could be more advantageous and easier to execute, such as a blockade, Siebens said, adding that China is advancing unification through political warfare and coercion.
