The Argentine government's decision to increase the price of the natural gas it exports to neighboring countries and to charge foreign motorists higher prices for gasoline have strained its relations with the governments of those countries, especially Chile. The trans-Andean relationship between the two countries has degraded since members of Chilean President Michelle Bachelet's Cabinet complained about the increases. The decision by Argentina to increase rates came after Bolivia increased the cost of gas it exports to Argentina.
