US President Donald Trump warned that France is at risk of a fresh trade war with America — declaring in an exclusive interview with The Post that unless Paris axes its digital tax on American tech giants, the US will “have no choice” but to slap 100% tariffs on French wines.

Axar.az reports, citing New York Post, Trump said he gave the blunt warning directly to outgoing French President Emmanuel Macron, demanding he ditch the 3% tech levy or face devastating duties in the American market, which accounts for a fifth of the French wine industry’s global sales — worth more than $2 billion annually.

“I asked him 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. “All [Macron] has to do is get rid of the sales tax, and he wouldn’t have that kind of pressure.”
