The area of trade and investment legislation is a striking example of the power that does justice in international law. Implementation is largely ensured by the government, which means that the industrialized world often controls the agenda. They have the power to sanction and enforce small states. The creation of the World Trade Organization (WTO) in 1995 marked a dramatic step forward in the development of trade and enforcement law mechanisms in relation to what existed under the General Agreement on Tariffs and Trade (GATT). The WTO has been widely criticized for challenging the „green zone“ agenda and other measures that penalize the South.  The new laws also place a heavy administrative burden on poor countries, which may not be bad in the long run, but which allows for costly compliance.  Such agreements may take the form of a mutual defence agreement, as seen in the North Atlantic Treaty Organization or in free trade agreements concluded by various Latin American countries (Powell, 2010). Indeed, the application of multilateral treaties has served as the basis for the current travel industry, where tourists have the right to visit other countries on the basis of the various bilateral and multilateral agreements of their government. The events of the 1990s and the perceived strengths and weaknesses of the ICTY have learned a great deal to draw attention to the idea of a global criminal court. The forerunner of the ICC was modelled on programmes such as the United Nations Commission on War Crimes, established by the Allies in 1943. In the post-war years, much was said about the idea of a permanent tribunal, but it was overshadowed by the Cold War and did not appear until 1989 as a means of combating international drug trafficking.
Both the ICTY and the ICTY (International Criminal Tribunal for Rwanda) stressed the need for a permanent body that is more deterrent and effective, since the costs of a permanent body could be lower than the start-up costs of ad hoc entities. States have created a set of developing international institutions to facilitate the establishment and maintenance of international law. The Hague Conference of 1899 established the Permanent Court of Arbitration, which was an institution in which states could attend dispute resolution. He was a forerunner of the Permanent Court for International Justice, established after the First World War in 1921.
