Bilateral and multilateral trade concord has an ability to facilitate and promoting trade between a group of countries; thereby, it reduces the likeliness of war or conflict. NAFTA is basically a bilateral agreement between Canada, the United States of America, and Mexico. It came into function in the year 1994. Though it was altered recently, it has the aim of reducing trade barriers among its member countries so as to promote the emergence of the economic bloc.
EU, in contrast, is a complex and very unique economic union existing among 28 European countries. It was initially created so as to facilitate trade between a limited number of states, but it later became a political union. All member states spend the same currency also, goods, people move freely within the EU borders. NAFTA and EU are distinct in terms of reach, scope, and implementation, as NAFTA is a purely economic agreement, EU, has grown into a territorial, social, and economic union.
