The United States, Canada, and Mexico are working together to modernize the North American Free Trade Agreement (NAFTA). In 2018, they reached a tentative agreement on changes in several areas including automobile trade, intellectual property, and dispute resolution. NAFTA was originally signed in 1994 to eliminate tariffs and trade barriers between the three countries. It has been controversial, with critics arguing it has led to job losses in the U.S. and other negative impacts on the economy.
美国、加拿大和墨西哥正在共同努力更新《北美自由贸易协定》（NAFTA）。在2018年，他们就汽车贸易、知识产权和争端解决等几个领域达成了初步协议。NAFTA最初于1994年签署，旨在消除三个国家之间的关税和贸易壁垒。但是它具有争议性，批评者认为它导致了美国的就业损失和其他对经济的负面影响。
