Mr Le Maire declared the two euro powerhouses would be calling the shots before getting Italy and Spain on board and presenting their proposals to the other 15 finance ministers.
And when asked if he thought the eurozone should work that way the tough-talking 49-year-old said: “That’s exactly it. I want political decisions to be taken.
“I’m not here to babble. We can’t afford to babble when there’s such urgency to take the eurozone to the next level.
“The roadblocks preventing a true eurozone reform have been known for almost 10 years, and nothing has been done.”
Mr Le Maire’s methods may not go down well with Madrid and Rome, and even less so in other capitals, but he insisted it was time for realism and not worrying about hurting other countries’ feelings.
And he stressed a June deadline for Franco-German agreement on the completion of the eurozone’s banking union, a EU “capital markets union” and harmonisation of corporate taxes was realistic, even though Germany is unlikely to have a proper government before March.
When asked if the June deadline was realistic, Mr Le Maire said: “If we can’t move forward in those three months, it would in reality mean that we aren’t keen on moving forward.
“In order to be able to make progress, we have identified the roadblocks.
“And our technical teams have started working on the specifics: this is not the same type of discussion as before.
“We don’t talk about general ideas, we’re looking at each and every technical detail in order to come up with an agreement.”
Mr Le Maire has been a key player Emmanuel Macron’s team since he became the surprise choice to head the finance ministry in May last year.
He was a Cabinet minister under conservative Presidents Jacques Chirac and Nicolas Sarkozy before becoming a contender for the presidential nomination of the centre-right Republicans.
He switched his support to François Fillon after defeat in the primaries but a few months later became the first party heavyweight to step away from the campaign when Mr Fillon broke a promise to retire if put under judicial inquiry.
