On 21st December, Taiwan’s "friendly nation" San Tome and Principe suddenly claimed for breaking up its relationship with Taipei, which raised the later to worry about that the other 21 “diplomatic allies” will follow the STP’s step. In ANBOUND’s view, Taipei’s “diplomatic pressure” largely relates to Tsai Ing-wen’s deny of 1992 Consensus, her telephone communication with American’s would-be President Donald Trump, as well as American’s attitude toward “One China” principle. Recently, American President Barack Obama signed the National Defense Authorization Act and accordingly it will upgrade the communication level between American and Taiwan’s military. Taipei expressed thanks to America. Given these reasons, Taipei inevitably will be the pawn in the political game between China and the US.
