On the basis of NAFTA, the United States, Mexico and Canada have agreed to cooperate in other agricultural for a, improve transparency and consultations on issues related to trade between countries. Since the adoption of NAFTA, U.S. trade interests have often expressed great satisfaction with the agreement. Trade between the three nafta nations has increased sharply, but this increase in trade activity has led to growing trade deficits for the United States with Canada and Mexico; the United States imports more from Mexico and Canada than it exports to these trading partners. Critics of the deal argue that NAFTA is responsible, at least in part, for these trade deficits and the striking loss of manufacturing jobs in the United States over the past decade. But manufacturing jobs began to decline before NAFTA. The NAFTA debate continues. Economists largely agree that NAFTA benefits North American economies. Regional trade grew sharply in the first two decades of the contract [PDF], which rose from about $290 billion in 1993 to more than $1.1 trillion in 2016. Cross-border investment also increased, with U.S. foreign direct investment (FDI) equities in Mexico rising from $15 billion to more than $100 billion over that period. However, experts also say it has proven difficult to draw the direct effects of the agreement on other factors, including rapid technological change and expanding trade with countries like China.

Meanwhile, discussions continue on the impact of NAFTA on employment and wages.
