墨、美、加3国于1991年6月就实现北美自由贸易问题举行了正式谈判。众所周知,在此之前,墨西哥政府一直以种种理由拒绝参加谈判。那么,当前墨西哥在与美国和加拿大仍存在着巨大的经济反差的情况下,为什么会一反过去立场,积极参加北美自由贸易谈判呢?本文拟从墨美关系的新发展、萨利纳斯总统的经贸改革以及自由贸易对墨西哥经济发展的利弊三个方面加以分析。 Mexico, the United States and Canada formally held negotiations on the realization of North American free trade in June 1991. As we all know, until then, the Mexican government has refused to participate in the negotiations for various reasons. Then, at present, with the huge economic contrast with the United States and Canada, why Mexico will take an active part in the North American free trade negotiations if it still has a huge economic ripple with the United States and Canada? This article is going to take the lead from the new developments in Mexico-U.S. relations, President Salinas Economic and trade reforms and the advantages and disadvantages of free trade on the economic development of Mexico.
