PARIS -- Presidents Emmanuel Macron and Donald Trump have agreed to extend negotiations on a dispute over a French tax on digital giants to the end of the year, postponing Washington's threat of sanctions against Paris, French officials said Tuesday.

French Finance Minister Bruno Le Maire, speaking before a Brussels meeting with EU counterparts, said: "Macron and Trump had a very constructive discussion... and they agreed to avoid all escalation between the US and France on this digital tax issue."

A French diplomatic source said the French and US leaders, who spoke by telephone on Sunday, agreed to give negotiations a chance to "find a solution in an international framework" and avoid "a trade war that will benefit no one".

Macron tweeted Monday that he had had a "great discussion" with Trump on the issue. "We will work together on a good agreement to avoid tariff escalation," he said.

On January 7, Paris and Washington had given themselves 15 days to reach a deal to avert the US threat of duties on up to $2.4 billion of French goods.

Le Maire, who has been conducting intensive negotiations for the last several weeks, had been scheduled to hold crunch talks on the issue with US counterpart Steven Mnuchin at the World Economic Forum in Davos on Wednesday.

After confirming the reprieve, Le Maire told journalists in Brussels that he spoke with Mnuchin by telephone on Sunday and "our technical teams are in contact day and night to work on a solution".

He stressed that "this remains a difficult negotiation.... A certain number of details need to be worked out, but I believe we're going in the right direction."

Le Maire declined, however, to say whether France would suspend its digital tax. "I am not going to get into the details of the negotiation. I prefer that that remains between Mnuchin and myself," he said.

Nevertheless, according to concurring sources, France is willing to suspend the tax "to provide some time" to find a solution under the auspices of the Organisation for Economic Co-operation and Development.

While the principle of the tax itself was not in question, the collection of payments scheduled for April and November was being suspended "to provide time for negotiations within the framework of the OECD," according to one source.

Another source said that France would suspend collection of the payment scheduled for April, "with the balance to be paid in November by the companies concerned".

The French presidency said on Monday that "France is pursuing its objective of fair taxation on digital companies and finding a compromise within the framework of the OECD."

France has said it would drop its tax if an international agreement is reached under the auspices of OECD.

After blocking the OECD talks for several years, Washington relaunched them last year only to make proposals in December which France rejected.

In an interview with the Wall Street Journal on the sidelines of Davos, Mnuchin said that the truce with France was "the beginning of a solution."

After France announced its tax last year, both Italy and Britain unveiled similar plans.

But Mnuchin said he hoped the two countries would reconsider.

"If not, they'll find themselves faced with President Trump's tariffs.

We'll be having similar conversations with them," he told the WSJ. (AFP)
