Since the beginning of the history of aviation, the use of aircraft for military purposes revealed an efficient and dangerous weapon in the arsenal of a State. First it was used as observatory post, and then the aircraft took a more active role in combat until it became a destructive and deadly weapon. The definition of military aircraft in international law is not clear as States only wish to regulate international civil air navigation and not state aircraft. On the other hand, the Law of armed conflict defines the status of every aircraft with their respective duties and rights in the conduct of hostilities. The interception of civil aircraft by military aircraft shall be done in accordance with the international standards adopted by the International Civil Aviation Organization in virtue of the Chicago Convention and it's limited to determine the identity of the aircraft. The use of deadly force against civilian aircraft in flight is equivalent of pronouncing the death sentence of its occupants without the hearing of a trial. Respecting the international standards of interception of civil aircraft is a necessity.

Though attempts have been made to regulate the multilateral trading system by the GATT 1947 which was but meant to form only part of an agreement on the stillborn International Trade Organization (ITO), the first rule based World Trade Organization (WTO) was established only in 1995 and a number of countries have acceded to it thence.
