The Pacific Alliance (PA) is an integration process that projects the commercial exchange of value-added products for its members. However, the external and internal crises have made the PA a volatile region in social and economic terms. This chapter analyzes the economic and trade policy trends in PA countries since 1990 and how they faced the different world and regional economic crises. From the particular analysis of the countries, there are similarities and differences in trade trends and the way to control crises. This chapter provides a general framework to review more specific approaches by sectors, industries, and companies.
