Negotiations between Greece and its creditors have ended without reaching a deal, a European Commission spokesman said.
The spokesman said there remained wide differences between Greece's reform plan and the requirement of its international creditors, Xinhua news agency reported.
Sunday's negotiations in the Belgian capital lasted for less than one hour.
Hopes to strike a deal now move to Thursday's Eurogroup meeting in Luxembourg which many believe is the last chance before Greece's EU bailout expires at the end of June.
