The current Round is seeking agreements under similar headings.

It therefore poses the risk of considerably extending the negotiations and diverting attention away from other areas of reform. But the sustainabilility of many domestic support policies requires imposition of trade barriers so reform of trade barriers may force governments into reforming domestic support without requiring specific international agreements. Quantitative assessment, using the GTAP applied general equilibrium model is used to analyse trade reform scenarios, with and without specific changes in domestic support. It is concluded that substantial trade expansion and welfare gains can be achieved even when domestic support is excluded from the multilateral agreement, and that improved market access makes a far greater contribution to welfare gains than reforms to domestic policies. Once substantive reforms to border policies have been achieved, attention can then be turned to the lower-priority task of reforming domestic suppor
