The commissioner added that the sides need to reach an agreement on a comprehensive set of reforms that would be "ambitious, realistic and financially sustainable," adding that the solution is not only possible, but absolutely necessary.
Greece is undergoing a deep economic crisis. Its overall state debt stands at $350 billion, of which $270 billion is owed to three of its major international creditors.
