German Chancellor Angela Merkel will meet International Monetary Fund chief Christine Lagarde and European Commission president Jean-Claude Juncker in Berlin on Wednesday, a spokeswoman said.
While the spokeswoman called the Merkel-Lagarde talks "a discussion on general themes," the meetings come amid wrangling over the latest review of Greece's 86-billion-euro ($92 billion) bailout programme, in which the Commission and the IMF are two key actors.
There will be "no public communication" about the content of the meeting, the spokeswoman said Friday.
Later, Merkel will meet Juncker for a "working dinner" addressing "current themes in European politics."
The Washington-based IMF and eurozone countries including Germany are at odds over how to handle the Greek debt crisis.
The IMF played a key role in two former schemes to keep Greece afloat in 2010 and 2012, but in recent weeks has expressed doubts about the sustainability of the country's debt and the budget surpluses demanded by its eurozone neighbours.
Germany refuses to accept any reduction of Greece's debt, but has also vowed not to take part in any extension of the aid programme if the IMF is not involved.
For its part, Greece hopes for a "political agreement in principle" with its creditors at a Eurogroup meeting of eurozone finance ministers on Monday.
A compromise is required to sign off on a second review of the bailout programme and unblock a tranche of loans Greece needs for debt repayments of seven billion euros this summer.
