伴随《跨太平洋伙伴关系协议》（TPP）的达成，美国积极推动构建“TPP轨道”为代表的亚太经济合作路径，以打破原有的区域合作均衡，亚太地区的政治、经济格局正在发生一系列重大改变。这种演变客观上与包括中国在内的东亚经济体以“东盟+”模式为代表的“东亚轨道”区域经济合作机制形成战略竞争，反映了未来一段时期东亚经济一体化进程，乃至亚太区域经济合作的复杂性和不确定性。尽管《跨太平洋伙伴关系协议》（TPP）的基本达成产生了广泛影响，但新地区主义的东亚合作或将成为亚太区域竞争性合作机制的融合构想，中美两国如何共同推进亚太自由贸易区（FTAAP）建设将可能成为未来亚太地区各方利益平衡的焦点。
With the Trans-Pacific Partnership Agreement（TPP）coming into effect，the political and economic landscape in the Asia-Pacific region is experiencing a series of important changes. The United States actively pushes for the “Track of TPP”，the new path for Asia-Pacific economic cooperation，which has tipped the original balance of regional cooperation. The “Track of TPP” is actually in strategic competition with the “Track of East-Asia” and the “Pattern of ASEAN+”，which is another relatively mature mechanism of regional cooperation among China and other major economies in East Asia. This reflects the uncertainties and complexities of regional integration in East Asia. Despite the wide influences of the basic consensus on TPP agreement，cooperation in East Asia under New Regionalism may be part of the competing cooperation mechanisms in the Asia-Pacific region. Besides，the question of how China and the U.S. jointly promote the construction of Free Trade Agreement of the Asia-Pacific（FTAAP）may become the focus in balancing relevant stakeholders’ interests in the Asia-Pacific region.
