The potential benefits of opening up agricultural markets are huge, especially for developing countries. The current approach to trade in agriculture may need to change to bring it more in line with global trade rules. New issues like food safety and the multiple roles of agriculture are important for developing countries. The upcoming WTO round is a chance for developing countries to push for faster changes in how farm products are traded. In exchange, they may need to open up their own markets more, which could also help rural people in poor countries.
