Bernard Cazeneuve, France's new Europe minister, said there should be "no taboo subjects" when EU leaders meet on 28 June to discuss measures to kick-start the EU's sluggish economy.
Chief among those is Eurobonds, which France wants to introduce rapidly as a way to mutualise debt in the euro zone and reduce the borrowing costs of the most fragile economies like Spain and Italy.
France and Germany have openly stated their disagreements on Eurobonds at the last EU summit in May, which French President François Hollande summarised in straightforward terms: "For now, Germany's line of thinking is that Eurobonds…could only be an end point, whereas for us they are a starting point."
For German Chancellor Angela Merkel, as well as European Central Bank President Mario Draghi, issuing jointly backed European debt would not make sense until the euro zone reaches some kind of fiscal union, a long process that will probably require another European treaty and further sovereignty transfers to Brussels – none of which are an easy political sell.
Greater integration, later
Speaking to the press in Brussels on Tuesday (29 May), Cazeneuve sought to play down Franco-German divergences on Eurobonds, saying the difference does not relate to whether they should be introduced or not but rather "when they should be done and the context in which they should be done."
Eurobonds, he explained, "could justify a greater integration of governance mechanisms" within the euro zone – but only at a later stage.
Pressed by EurActiv to elaborate, Cazeneuve refused to give specific conditions under which France could agree to additional sovereignty transfers to Brussels.
"For us, [Eurobonds] must be a starting point in this process of greater integration," Cazeneuve said, citing "differences of opinion" on the "timing" of Eurobonds and "the context" in which they should be introduced.
"If in this perspective the discussion focuses on greater modes of integration, these topics will be addressed in due time," Cazeneuve said, adding: "We will not indicate now what the steps are when those steps are part of the negotiation. All this must be made by doing."
"It is the dynamic of the dialogue between European Union countries to ensure recovery, growth and fiscal discipline ... that will decide on the steps, objectives, methods, to reach an agreement. Let the discussion be continued."
Other French officials are less reserved.
Speaking to EurActiv.fr, Michel Barnier, the EU's Internal Market Commissioner, said sovereignty transfers should not be a taboo subject, adding that time had come for "a federalist leap" in European integration that would lead to the creation of Eurobonds.
Alain Lamassoure, a French centre-right MEP and former Europe minister, told EurActiv that France should better focus first on ratifying the treaty on fiscal discipline and curb its public deficit if it wants to address the euro zone crisis and create the conditions for growth.
"People who say they want greater economic integration, the first thing they need to do if they are consistent with themselves, would be to substantially increase the European budget. But France says it wants to cut the EU budget by €100 billion over the next seven years," he told EurActiv. "This is rubbish!"
France, together with five other European countries, including the UK and Germany, has committed to cap the EU budget to 1% of GDP over the period 2014-2020.
Speaking in Brussels, Cazeneuve said the current government would stick to this commitment, saying France's contribution to the EU budget, which amounts to roughly €20 billion annually, should be kept under check in order to curb deficits.
"If we want to honour the commitments we made to the Union in the recovery of our public finances, it is imperative that we ensure that our contribution is useful and reasonable at the same time," Cazeneuve said.
Lamassoure, for his part, challenged French President François Hollande and German Chancellor Angela Merkel to kick-start growth by agreeing on a bigger EU budget.
"I look forward to hear how these people are going to tell us that they want at the same time to boost economic growth and reduce the EU budget, which is the most effective common instrument to support economic activity," Lamassoure told EurActiv.
