Portugal Colonial - Macron, Scholz set for frosty lunch amid Paris-Berlin tensions

Russia's invasion of Ukraine -- less than three months after Scholz took office last December -- pitched their countries into crisis mode and decisions taken under the pressure of the war and its knock-on effects have raised hackles on both sides.

Berlin's move to spend up to 200 billion euros ($200 billion) subsidising soaring gas prices and refusal to consider an EU-wide energy price cap nettled Paris and other European capitals, who fear the effect on their energy costs.

And France also sees commitments to cooperate on defence procurement floundering, given Germany's plans for a shared missile shield with other NATO nations using American equipment.

Longer-term projects to jointly develop new fighter jets and tanks also face reluctance from big arms companies, which has worsened since war broke out.

The depth of the differences was laid bare by the recent delay to a regular joint cabinet meeting between Paris and Berlin, which would have been Scholz's first as chancellor.

And limited expectations for Wednesday's talks were clear from the schedule released by Macron's Elysee Palace office, which did not provide for a joint press conference before or after the 12:30 pm (1030 GMT) lunch.

"The two leaders will continue their talks on defence, the economy and energy with the aim of strengthening Franco-German cooperation," the presidency said in a statement.

- 'Destabilising' Ukraine war -

Differences between the EU's two largest and most populous economies -- in the past often the brokers of compromise among the bloc's 27 members -- have come at exactly the wrong time.

Russia's invasion and the resulting disruption to the energy system have coincided with rising tensions between China and the West, as well as fears that more isolationist forces could return to power in Washington.

Berlin and Paris also differ on how to adapt the European Union to be more agile faced with the new challenges, and how quickly to admit new members.

"We can't allow ourselves not to have a united, strong Europe at this moment in history," former French foreign minister Dominique de Villepin warned on France Inter radio.

"That starts with a fruitful French-German dialogue," he added.

Moscow's burning of bridges with Europe means Germany faces "a change to its model whose destabilising nature must not be underestimated", Macron has said.

That was made clear earlier this year, when Scholz announced a "new era" in German defence policy supported with massive spending on its creaking military.

Although Berlin's allies welcomed the change of direction after years of under-investment, the flow of cash has not translated into big contracts for EU or especially French arms firms -- one of the undertones of Macron's calls for greater European sovereignty.

Instead Germany is rushing to buy big-ticket American-made items like F-35 fighter jets and Patriot air defence systems.

- 'No fundamental crisis' -

Many observers suggest that spats are inherent to the relationship between two large nations with interests that often diverge.

"The truth is that it's a marriage of necessity" between France and Germany, a French diplomatic source said.

"This isn't a fundamental crisis, it's the basis of the relationship," they added.

"This French-German relationship has always been made up of chilly patches, moments of tension and then warming up again," agreed Alexandre Robinet-Borgomano, a German politics expert at French think-tank Institut Montaigne.

"It's often during moments of crisis where a European response is indispensable that France and Germany manage to overcome their difference to propose a joint solution."

"France is our closest ally. There has been a lot of speculation in recent days, but I think a lot of it's made up," a German government spokesman said.

In Brussels, "I trust in the determination of the French president and German chancellor," European Council chief Charles Michel has said.
