The Pacific Alliance was founded in June 2012，aimed at realizing the free movement of goods，services，capital and persons among member countries and serving them as a platform for economic integration into the global system and especially into the Asia-Pacific region. Since the foundation，the integrating process continued to be deepened and has produced remarkable initial fruits. Now the alliance is facing major challenges such as a small volume of trade among the members，immense difficulties in promoting free trade of agricultural products and service，and heavy competition from outside. As an observer，China has forged strong economic and trade ties with the bloc and is seeking a closer partnership with it.
