The sensitive issues across the Taiwan Strait with respect to sovereignty, national identification, parity, foreign intervention and threat of force can be organized as six games. On behalf of Taiwan, three of them are "prisoner's dilemma games", while two of them are "deadlock games". On behalf of Chinese Mainland, five of them are "deadlock games". One of them is expected to transfer from a "deadlock game" into a "prisoner's dilemma game" for both sides. Basically, the interactions across the Taiwan Strait can be classified as a game to swing between deadlock and prisoner's dilemma. Compared with that of Chinese Mainland, the possibility of Taiwan to shift from a "deadlock game" into a "prisoner's dilemma game" is higher. In other words , Taiwan is more pragmatic than Chinese Mainland. If Beijing and Taipei are able to transfer their games from deadlock into prisoner's dilemma, the prospect of "mutual cooperation" across the Taiwan Strait will be much brighter. The key to enhance this possibility is dependent upon whether or not Taiwan is able to maintain its long-term goal of Chinese reunification and upon whether or not Chinese Mainland is able to provide Taiwan with sufficient sense of security. Otherwise, the game across the Taiwan Strait will end up with a deadlock.
