DAVOS, Switzerland — European leaders, rattled by US President Donald Trump's latest global gambit, are looking to present a united front in Davos, as business leaders warned against an emotional response to Trump's ambition to take over Greenland.

French President Emmanuel Macron said the European Union should not bend to "the law of the strongest", adding that it was "crazy" that the bloc was having to contemplate using its "anti-coercion instrument" against the United States.

"We do believe that we need more growth, we need more stability in this world, but we do prefer respect to bullies," Macron told the World Economic Forum's annual meeting, the day before Trump's arrival in Switzerland.

Without referring directly to Trump, European Commission President Ursula von der Leyen highlighted a need to respond to seismic shifts in the world and said the speed and scale of change had driven a consensus in Europe on independence.

"It is time to seize this opportunity and build a new independent Europe," she said in a speech.

Belgium's Prime Minister Bart De Wever said the 27-member EU was "at a crossroads" where it must decide on how to get out of a "very bad position".

"So we should unite and we should say to Donald Trump ...'You're crossing red lines here.' We either stand together or we will stand divided," De Wever said on a panel discussion.

Swedish Deputy Prime Minister Ebba Busch told Reuters that attempts to win over Trump with flattery, as some European leaders have tried in the past, would not work.

"Stroking the cat along the line of its fur is not going to do the trick this time. The EU needs to toughen up and hold the line," she said, adding that the bloc needed to keep options for trade retaliation "locked and loaded".

Trump announced tariffs on Saturday on imports from European allies that oppose the US acquiring Greenland, an autonomous territory of Denmark.

Growing challenges

European governments, which are facing growing challenges from populist, nationalist parties, have been at odds over how to respond to the tariff threat while maintaining US support for Ukraine.

Macron said Europe should not accept a world in which might makes right and called for bold measures to defend European industries.

"Let's not be shy. Let's not be divided. Let's not accept a global order, which will be divided by those who claim to have the bigger voice," he said.

Macron's office said on Wednesday that France has asked for a NATO exercise in Greenland and is ready to contribute to it.

The French president also appeared to see an opportunity for Europe in Trump's chaotic policies.

"We have a place where the rule of law and predictability is still the rule of the game, and my guess is that it is underpriced by the market," he said in his speech.

However, some senior bankers and executives in Davos, who spoke on condition of anonymity, said they saw the response from European leaders to Trump's moves as emotional rather than pragmatic. Two of them suggested that the continent needs to look beyond how the US president delivers his message and then engage in negotiations.

"But they won't even want to have that conversation, because they're so offended by the style," one senior banker told Reuters."And so what you have in Europe is a very, very delicate balance of a continent that cannot move together."

European countries say Trump's threat of new tariffs would violate a trade deal reached last year, and EU leaders are set to discuss possible retaliation at an emergency summit in Brussels on Thursday.
