France's President Emmanuel Macron said Monday he was opposed to mutualising "old debt" between eurozone countries, but said he was open to sharing future burdens.

"I am not a promoter of the mutualisation of old debt" within the eurozone, said Macron after meeting Chancellor Angela Merkel, adding however that the joint financing of future projects should be considered. One of Berlin's red lines is paying off the debt of other eurozone members.
