面对发达国家主权债务危机，亚洲经济陷入了内热外冷的尴尬境地，经济增速将不可避免地放慢，但仍然会充当全球经济的“火车头”。亚洲经济的持续高速增长正在吸引区域外大国的关注和进入。其中，美国“重返亚洲”战略最为突出，并开始进入实施阶段。这一战略的实施不仅符合美国的利益，而且也迎合了中国周边国家的骑墙战略目标。为此，中国周边环境正在进入一个空前复杂的阶段：因跨太平洋经济伙伴关系协定(TPP)，中国多年来致力于推进的东亚区域经济合作进程有可能陷入停滞；区域外大国与区域内国家寻求新的利益交集；部分国家甚至借机利用区域外大国的进入侵害中国的核心利益，如南海问题；中国周边正在成为大国之间的竞技场。因而，中国需要新的理念处理好周边关系。
On account of the shock of sovereign debt crisis, Asian economy fell into a dilemma in which external downturn risk coexist with internal inflation risk, and its growth will slow down inevitably, but it will act as an engine of global economy. Sustained growth in Asia has attracted more outsiders' attention. Washington's return to Asia strategy has been put into force in 2011. The strategy not only be in the interest of United States, but also cater to the needs of the hedge strategy in some Asian countries. As a result, China's surrounding environment is going into highly unstable phase: because of TPP, the East-Asian regional economic integration process China has pursued may stagnate; Outsiders seek new common interest with insiders in Asia; with the help of outsiders, some small Asian countries try to harm China's core interest, e.g. South-China Sea Issue; China's surrounding is becoming an arena of great powers. Thus, China needs to correctly handle contradictions with its neighbors by new idea.
