2012年亚太地区经济受“欧债危机”的影响，外需下降导致区内经济联系和相互依赖加深。区域一体化的建设和发展是2012年亚太经济关系新变化的集中体现。跨太平洋战略经济伙伴关系协定(TPP)获得较快发展，进行了四轮谈判，在具体协议上取得进展，且墨西哥和加拿大已正式加入谈判。中日韩自由贸易区的发展呈现“一波三折”，领导人会议和经贸部长会议均已决定年内启动正式谈判，但中日和韩日的领土争端将搁置谈判进程，中日韩自贸区预计在未来几年难有发展。区域全面经济伙伴关系协议(RCEP)是东盟在2012年2月提出的区域一体化安排，正式谈判将在2012年底开启。欧亚太平洋合作倡议是俄罗斯在2012年APEC峰会上提出的区域一体化构想，目前处于新提出阶段，尚无进展。就当前的发展前景而言，TPP推进最快，RCEP次之，中日韩FTA位列第三，而欧亚太平洋合作倡议很难实现。
Regional integration progress was the main development of Asia-Pacific economic relations in 2012. TPP developed quickly and had four round negotiations in 2012, with Mexico and Canada formally taking part in the negotiation. China-Japan-South Korea FTA negotiation had been decided to be initiated in leaders meeting, but the territory disputes between China and Japan, South Korea and Japan would delay the negotiation process. Regional Comprehensive Economic Partnership is dominated by ASEAN and will be formally open for negotiation at the end of 2012. Europe-Asia Pacific cooperation proposal is put forward by Russian in the 2012 APEC Summit, which is still in the proposal stage and has no essential progress now.
