TPP participants such as Vietnam, Malaysia, and Japan have higher tariff and non-tariff barriers against some products that the US would like to be able to sell them than the US does against their goods. Liberalization would thus benefit US exports to Asia more than Asian exports to the US.
哪怕是从这一逻辑出发，你也可以找出正在进行的贸易谈判的“美国”利好。美国市场已经相当开放；TPP参与国，如越南、马来西亚和日本等，它们针对一些美国有可能能够卖给它们的商品所施加的关税和非关税壁垒比美国对它们所提供的商品所施加的壁垒更大。因此，自由化给美国对亚洲出口带来的好处要多于亚洲对美国出口。
