NAFTA, the largest free-trade agreement in the world, came into force during the Bill Clinton´s years (1993). It created a free-trade zone comprising Mexico, the United States and Canada. It has boosted trade, investment, prosperity and economic interconnection of the three parts. Although it has been modified by an initiative of the current Donald Trump´s administration, free trade exchanges will continue. The Clinton years were important for free trade around the world. The Senate approved the GATT treaty. Other countries and regions followed and reached free-trade agreements after NAFTA.
