This is a report about developing country participation both in the current Uruguay round and beyond, arguing that over the post war years a climate of mistrust has evolved between developed and developing countries over trade issues. Developed countries have argued developing countries to take on more discipline over their own trade policies and developing countries have questioned the credibility of multilateral commitments developed countries have made. Major differences of opinion were evident in the period immediately preceeding the launching of the Uruguay Round over the issue of how services should be treated in the GATT and recent years have seen indications of potentially major change. Developed country responses to maintain this forward momentum are suggested and concrete options for the longer term looked into.
