The International Union of Students (IUS) was joined by regional students\' organizations from around the world for the September 13, 2003 Global Student Day of Action to Defend Public Education. The action was aimed at the World Trade Organization (WTO). Students around the world are calling for all levels of education to be removed from the General Agreement on Trade in Services (GATS), a set of rules about international trade in the service sector adopted by the WTO. GATS forces developing countries in particular to open public services, health care and public education to privatization by giant corporations.
