German Chancellor Angela Merkel is insisting that Greece must implement the reforms it agreed to in exchange for rescue loans from international creditors.
German news agency dapd reports that Merkel said at the Group of 20 summit in Mexico that "no departures can be made from the reform measures."
She added that "we have to count on Greece sticking to its commitments."
Stocks in Europe fell Monday after Merkel's comment. Markets are widely expecting that Greece will get more time to make budget cuts to avoid an aid cutoff that could see it leave the euro.
