The North American Free Trade Agreement (NAFTA), which was signed in 1994, is a trade PACT between the United States, Canada, and Mexico. The acronym for this agreement is PACT, which stands for the 'Progressive Agreement for Trans-Pacific Partnership'. This agreement has allowed for the free flow of goods and services between the three countries, as well as the elimination of tariffs and other trade barriers. It has also helped to create jobs and economic growth in all three countries.
