Abstract：Since the U.S. strategic move of “Pivot to Asia Pacific”, scholars of the U.S. think tanks have conducted plenty of researches on South China Sea issue, aiming to influence the government’s policy in different ways. Based on analysis of issues such as present situation of Sino⁃U.S. game in the South China Sea and China’s South China Sea strategy, scholars think that China has taken strategies such as “Delaying”, “Tailored Coercion”, and “Cabbage Peeling” to strengthen its control over the South China Sea.They also proposes a variety of countermeasures, such as “cost escalation”, “law warfare”, and “humiliation warfare”. These proposals are broadly subject to three categories: “increasing repression”, “support along with containment”, and “joint effort to ease the conflict”. The Obama administration generally adopted the strategy of “support along with containment”, while it is still unclear that which kind of policy Trump government will take China needs to pay attention to studies of the U.S. think tanks on South China Sea and their impacts on the U.S. Administration, and meanwhile plan corresponding countermeasures to cope with the possible tension in the South China Sea.
