President Donald Trump has warned France must scrap a 3% tech "sales tax" or face 100% tariffs on U.S. imports of its wines and champagne, the NY Post reported Monday.

The president issued the threat ahead of this week's G7 summit in Évian-les-Bains, France.

"I asked [President Macron] not to charge American companies, and if they do, I have no choice but to charge a 100% tariff on all champagnes and all wines coming out of France," Trump told the Post.

The digital services tax, which was approved by French lawmakers in 2019, involves a 3% levy on gross revenues generated in France by large technology companies, including U.S. giants such as Amazon, Meta and Alphabet.

Exports to the U.S. make up about one-fifth of the French wine industry's total global sales, at about $2 billion annually.
