The US has been establishing a template for its PTAs that includes several items unrelated to trade. So it is no surprise that the TPP template includes numerous agendas unrelated to trade, such as labor standards and restraints on the use of capital-account controls, many of which preclude China’s accession.
美国对它的优先贸易伙伴附加了许多与贸易无关的条款，因此不出意外在跨太平洋伙伴关系协议上也附加了许多与贸易无关的议程，包括劳工标准以及对资本账户控制的限制，而这些议程中的许多条款都试图将中国排除在外。
