Mr Trump voiced his anger in a Tweet on Friday, in response to French plans to tax multinational firms like Google.
French authorities argue that the firms pay little or no corporate tax in countries where they are not based.
The Trump administration has said the tax unfairly targets US tech giants.
"France just put a digital tax on our great American technology companies. If anybody taxes them, it should be their home Country, the US," Mr Trump wrote on Twitter.
"We will announce a substantial reciprocal action on Macron's foolishness shortly. I've always said American wine is better than French wine!"
Asked about the issue in the Oval Office later, Mr Trump, who is teetotal, said: "I've always liked American wines better than French wines. Even though I don't drink wine. I just like the way they look." » | BBC | Friday, July 26, 2019
