The Latin American nations of Mexico, Peru, Columbia, and Chile just became a lot closer. All four countries signed an agreement called the Pacific Alliance, which will lift tariffs on 92 percent of goods and services traded among the member nations.

The combined GDPs of the four countries accounts for over 1/3 of Latin Americas GDP. (Image source: huffingtonpost.com)
