In addition, measures to protect sea turtles are legitimate under Article 20 (i.e. XX) of the GATT, which regulates various derogations from WTO trade rules, provided that certain criteria such as non-discrimination are met. The World Trade Organization (WTO) was established in 1995 as a successor to the General Agreement on Tariffs and Trade (GATT), which was discussed in the last section. The WTO is committed to reducing barriers to trade. Nations around the world are coming together through the WTO to negotiate how to reduce trade barriers such as tariffs. WTO negotiations take place in “rounds” in which all countries negotiate an agreement to promote trade, take a break for one or two years and then start negotiations on a new agreement.
