Washington D.C., Dec. 20 (CNA) The head of an American think tank suggested Thursday that Taiwan should purchase submarines to strengthen its naval deployment amid the growing military imbalance between Taiwan and China. Taiwan can put pressure on the Chinese armed forces with a stronger naval defense that includes submarines, argued Scott Bates, president of the Washington-based Center for National Policy (CNP), at a panel discussion in which he and two other U.S. scholars shared their observations from a trip to Taiwan in early December. “It seems this (submarine) is a perfect naval asset for the defense of Taiwan in the protection of freedom and navigation in the Straits, in the South China and in the East China seas. And the current array of submarine forces that Taiwan has is not up to achieving those missions,” Bates said. Although Taiwan’s policies do not include attacking Chinese civilians, its Air Force and Navy are not currently strong enough to deter China’s People’s Liberation Army, Bates said. Taiwan’s people may currently be unwilling to spend too much on national defense, which can cost a lot, but Taiwan still has to recognize the military imbalance across the Taiwan Strait, Bates warned.
