The Financial Post reports in its Tuesday edition that President Donald Trump threatened to slap a 100-per-cent tariff on French wine and champagne unless Paris removes a digital services tax on tech firms. An Agence France-Presse dispatch to the Post reports that France imposed in 2019 a 3 per cent levy on the revenues earned by technology firms -- including American giants such as Meta, Amazon.com, Apple and Google parent Alphabet –- within the country's borders. French President Emmanuel Macron is due to host Mr. Trump on Monday before the G7 summit gets started. Mr. Trump said he asked Mr. Macron ""not to charge American companies," according to the New York Post. "If they do, I have no choice but to charge a 100-per-cent tariff on all champagnes and all wines coming out of France," he was quoted as saying. Mr. Trump said, "All Macron has to do is get rid of the sales tax, and he wouldn't have that kind of pressure." French Federation of Wine and Spirits Exporters president Gabriel Picard called for preserving a "balanced and constructive trade relationship between France and the United States in the interest of both economies." The United States is the biggest importing country for French wines and spirits.
