U.S. President Donald Trump on Tuesday threatened to impose 200% tariffs on French wines and champagne, as French President Emmanuel Macron is reportedly set to refuse joining his “Board of Peace” on Gaza.

When asked for a response by a reporter in Miami, Trump said “Well, nobody wants him because he’s going to be out of office very soon. So you know, that’s all right. What I’ll do is ... I’ll put a 200% tariff on his wines and champagnes, and he’ll join. But he doesn’t have to join.”

The Board of Peace is a global body endorsed by the United Nations Security Council in November last year, established to oversee the Israel-Hamas ceasefire.

Invites to various world leaders have been sent to be on the board, including to Russian President Vladimir Putin, UK Prime Minister Keir Starmer and Indian Prime Minister Narendra Modi.

Trump also reiterated his plans to control Greenland, saying that European leaders “won’t push back too much.”
