MADRID (Reuters) - The European Union may have to establish a mechanism to help out countries with financing difficulties after a 30 billion euro aid package agreed for Greece last weekend, Jean-Claude Juncker, chairman of the Eurogroup of finance ministers, said in a newspaper interview on Thursday.
"We have resorted to these loans (for Greece) because there was no other solution within the European Treaty. For the future we will have to install a European mechanism without allowing some member states to relax and not balance their books," Juncker was quoted as saying in an interview with Spanish newspaper Expansion.
"Nor is a change in the Treaty ruled out," he added.
Juncker also described the Greek aid program as "credible."
