Though being accessed into the WTO in 2002, Taiwan is still the outsider of the FTA games. The booming FTAs hinder Taiwan to compete equally with other global rivals. Taiwan is so eager to sign a FTA with the US, which has been the most important trade and diplomatic partner of Taiwan. There are however some concerns, e.g. intellectual property right protection, sensitive agricultural market liberation, and objection of China, that make the US hesitate to negotiate with Taiwan on such issue, though the US is supposed to gain even more than Taiwan. This paper is to explore why the Taiwan-US FTA can not succeed and what approaches Taiwan should take at the moment in time.
