The signatories of the European Energy Charter, the founding political document of the Energy Charter Process adopted in 1991, were joined by twenty new countries to work on a revised text, which will reflect more adequately the challenges faced by energy producing, consuming and transit countries, developing as well as developed economies. While some countries like China, Indonesia or Pakistan have been active observers before, the negotiation process also attracted new countries like Argentina, Chile, Colombia, Egypt, India, Iran, Mexico, the Philippines, South Africa and Thailand.

It is envisaged to adopt the final text of the International or World Energy Charter at a High-Level Conference in The Hague, the Netherlands, in spring 2015.
