Act 3: When?
On 1 January 1994 the North American Free Trade Agreement (NAFTA) entered into force, creating a trilateral free-trade bloc among Canada, Mexico and the United States with a combined population of more than 360 million. Negotiated under President George H. W. Bush and brought into law by President Bill Clinton, NAFTA progressively eliminated most tariffs on goods traded across the three economies and set rules on investment, services and intellectual property. It became a defining symbol of the post-Cold-War surge in regional and global economic integration, accelerating cross-border supply chains and the relocation of manufacturing, especially to Mexican factories. The agreement was politically divisive from the outset: supporters credited it with boosting trade flows and consumer choice, while critics blamed it for job losses in some manufacturing sectors and for pressure on Mexican farmers. Its launch coincided with the Zapatista uprising in Chiapas the same day. NAFTA shaped two decades of North American commerce before being renegotiated and replaced by the United States-Mexico-Canada Agreement (USMCA), which took effect in 2020.
