Abstract: The Pacific Alliance (PA) was constituted on April 28, 2011 by Mexico, Colombia, Chile and Peru. It represents a market of 209 million people with a GDP of over 2 billion USD. It has more than 35 percent of GDP in Latin America and concentrates 50 percent of Latin American exports to the world. PA as regional integration instance that moves progressively to the openness of the movement of goods, services and investments and, shows even more the importance of the Asia Pacific region, whose economic dynamics and competitiveness achieved in the XXI century, presents a greater challenge to Latin American economies. With the integration process that keeps the four countries of the PA, it is necessary to extend cooperation with APEC, particularly in green economy area as an alternative to the challenge of the problems of climate change, the Kyoto protocol and technological change, among others issues, being an alternative to address the deterioration of renewable and nonrenewable resources in the various PEC economies. The authors present the PA as a promising regional integration initiative that should use the experience of APEC to open a field of collaboration that allows the rapprochement between these two regions, in order to promote friendly competition with the environment. The experiences followed by each of the member economies of the PA are presented as a suitable platform to search for mechanisms intra and interregional collaboration that enable green economy that should be aspirated.
