Energy liberalisation is carried out through GATS in the WTO and regional commercial agreements such as the Andean Pact and FTAA (Free Trade Area for the Americas), the latter having a deep impact nowadays. Regarding trade in services, Colombia, as a WTO Member, accepts that the GATS negotiations will promote the country’s economic growth and development. These are arguments expressed by developed countries that support the GATS agreement and which are reflected in the WTO Ministerial declaration of Doha (November 2001), which started a new round of negotiations for all WTO members.
