World Trade Organization(WTO)is an organization that intends to supervise and liberalize international trade. The organization officially commenced on 1 January 1995. The organization deals with regulation of trade between participating countries; it provides a framework for negotiating and formalizing trade agreements, and a dispute resolution process aimed at enforcing participants adherence to WTO agreements, which are signed by representatives of member governments and ratified by their parliaments. Among the various functions of the WTO, these are regarded by analysts as the most important: It oversees the implementation, administration and operation of the covered agreements. It provides a forum for negotiations and for settling disputes. Additionally, it is the WTOs duty to review and propagate the national trade policies, and to ensure the coherence and transparency of trade policies through surveillance in global economic policy-making. Another priority of the WTO is the assistance of developing, least-developed and low-income countries in transition to adjust to WTO rules and disciplines through technical cooperation and training.
