With regard to a possible multilateral framework on competition policy, discussions have been underway at various international organizations including the WTO. This issue has been one of the main issues at the WTO for it is believed that anti-competitive practices undermine the gains of trade liberalization. Opinions exchanged at the WTO Working Group on the Interaction between Trade and Competition Policy show that a multilateral framework is necessary to deal with competition policy-related trade concerns and for the contribution of competition policy to international trade and development. However, discussions have not been developed into a formal negotiation stage, due to the lack of consensus on the modalities for the the multilateral framework agreement. While evaluating various approaches to a possible multilateral framework and looking into the WTO's work on the basic elements of the multilateral framework under the Doha Mandate, this paper envisons what should be a right direction to pursue for the future negotiations on a multilateral framework on interaction between trade and competition policy. Although the Cancun Ministerial Conference failed to reach an agreement on the modalities of a multilateral framework on competition policy, there is no doubt that negotiations will continue in the future. This paper is aimed at contributing to such progress.
