WTO helps cross border trade transactions take place predictably, freely and smoothly based on international trade rules and regulations set by the organization itself; making it the only international organization setting and dealing with global rules on international level trade transactions. Thus, this expected opportunity is the driving engine encouraging Least Developed Countries accede to WTO. Regarding the case of Ethiopia; Ethiopia is one of the many LDCs under WTO accession process, hence negotiating since 2003. Ethiopia's major export commodity is coffee which is the backbone of the country's overall economy.Ethiopia's probable accession in principle will bring new market opportunity for its coffee export,the export sector might not benefit from any substantial market access if domestic supply side constraints continue to be major obstacle for trade.
