For the multilateral dispute settlement system of World Trade Organization (WTO), implementation is the last part of the multilateral dispute settlement and is an essential element to settling disputes in the multilateral trading system. Without the implementation of the ruling, such a system would thus turn to be futile. In regard to the challenges relating to ruling’s implementation, perhaps the most controversial problem is the authorized retaliation mechanism.This article attempts to analyze in depth the challenges faced in the WTO’s authorized retaliation mechanism, particularly its institutional defects. The article starts with proposals made by developing nations to reform the authorized retaliation mechanism. Finally, this paper puts forth several new proposals for more favorable as well as efficient approaches towards the authorization of the retaliation mechanism in the WTO.
