Article 19.2 provides that “the Parties recognize that it is inappropriate to promote trade or investment by weakening or reducing the protection afforded by their respective environmental laws.” The Australia-United States Free Trade Agreement (AUSFTA) is a preferential trade agreement between Australia and the United States, modeled on the North American Free Trade Agreement (NAFTA). AUSFTA was signed on 18 May 2004 and officially entered into force on 1 January 2005. A coalition of unions and other groups opposed the deal because it would create problems similar to those of NAFTA. [indicate] Chapter 2 of the Free Trade Agreement sets out the conditions applicable to the types of goods that are subject to non-discriminatory treatment. .
