Since the 1990s, Latin American states have sought to attract large-scale foreign investment by implementing specific policies and regulatory regimes aimed at attracting investors from abroad. This trend has, however, recently seen a reversal, and many Latin American countries, such as Mexico, Colombia, and Peru, have watered down their investor-friendly policies, specifically as concerns their natural resources. Chile, by and large, has not been at the forefront of this Latin American trend, but recent changes to its Mining Law imposing new taxes on large mining companies involved in copper production raise concerns.
