Prime Minister Alexis Tsipras has arrived in Brussels to meet with the heads of the International Monetary Fund, the European Central Bank and the European Union's executive Commission.
The meeting is meant to smooth over some differences on the reforms that Greece proposed to creditors in exchange for rescue loans that it needs to not default on a debt payment June 30.
Later in the day, the 19 finance ministers from the eurozone states will discuss the proposal in more detail, before government leaders meet for a summit on Thursday.
The IMF has been cautious about Greece's proposed reforms, which are heavily focused on tax increases that can hit businesses, rather than public spending cuts.
