De Facto States are there and the international community needs more options for them. Scholars have discussed three possible alternatives for dealing with the reality of de facto states. The first option would be the so-called "Ethiopian model" which takes its name from the negotiations that used the Ethiopian Prime Minister Meles Zenawi to the interim government Eritrea in the early years of the nineties of last century. This politician called on foreign governments, investors and organizations to deal directly with the provisional government of Eritrea before the referendum on independence in 1993. In short, the then Prime Minister of Ethiopia broke the issue of final status Eritrea relations with his government and foreigners allowed to maintain different levels of contacts that they identify with the Eritrean government. The second potential alternative is called "Model GATT / WTO," shorthand for the World Trade Organization and its predecessor body, the General Agreement on Tariffs and Trade, in which members are contracting parties and not necessarily sovereign states. This system was originally established so that the colonies had not yet received their independence could adhere to the GATT in its inception in 1947. The two main requirements for membership in the GATT / WTO were a government: represent a customs territory to keep its policies trade and were responsible for these trade policies and may modify them in accordance with future efforts of the GATT / WTO. The third alternative is the "Taiwan model." This has nothing to do only with Taiwan maintains diplomatic relations with 20 nations, but above all, trade links, cultural and other countries has established that have not yet recognized as a sovereign state. No doubt they all have their limitations and none should be followed to the letter, since each state is different Facto, but these models show some of the ways by which Facto States could be recognized as sovereign states. Despite the isolation and ignorance surrounding the de facto state, and although they are there often are controversial, each case needs to be analyzed and taken into account.
