The EU-Mercosur free trade agreement is finally supposed to move forward after many years of stalemate. But a meeting of negotiators from both sides in Buenos Aires this Wednesday and Thursday has now been postponed until May. The reason: The Mercosur side, in particular, needed more time to prepare for the additional declaration on sustainability demanded by the Europeans, according to EU circles. And precisely this additional declaration is causing a lot of criticism among the concerned South American countries, report Daniela Chiaretti and Till Hoppe.
