While on French soil, Trump also intends to raise with Macron and the other leaders the issue of a digital services tax that France has imposed on major technology companies such as Google and Facebook despite Trump's threats of retaliatory tariffs on French wine.
This year, Trump picked a fight with Denmark, a longtime US ally and member of North Atlantic Treaty Organisation, before heading to the G-7.
In another piece of brinkmanship, he also confirmed right before departing on the Marine One helicopter that he would retaliate against France's iconic wine exports if President Emmanuel Macron didn't retreat on a new tax that will hit United States digital giants like Google.
"Our tariffs are very good for us", Trump said.

The prospect of a prolonged trade war between the world's two largest economies has cast a shadow over the G7 and other economies.

Trump's fireworks at the Charlevoix summit in Canada past year prompted foreign policy analysts to dub the Group of Seven nations the G6+1. Speaking to reporters, Mr. Trump highlighted the "special relationship" between the USA and France.
Hours before leaving for Biarritz, Trump reacted angrily to China's move to impose retaliatory tariffs on more U.S. goods, even saying he was ordering USA companies to look at ways to close their operations in China.
Speaking to reporters at the White House, Trump said, "Frankly I don't want France going out and taxing our companies".

G7 leaders were greeted by a mass protest outside Biarritz, though 13,000 police have been deployed to keep them far from view.
"The top capitalist leaders are here and we have to show them that the fight continues", said Alain Missana, 48, an electrician wearing a yellow vest - symbol of anti-government demonstrations that have rattled France for months.
European leaders are also using the summit to mount a tough push for action against fires in the Amazon rainforest, despite Brazilian right wing President Jair Bolsonaro's angry response to what he sees as outside interference.
Macron said Bolsonaro had lied in playing down concerns about climate change at a G20 summit in Japan in June, and threatened to veto a trade pact between the European Union and the Mercosur bloc of South American countries.
"Our house is burning".
The tweet was later corrected with the link to Macron's official Twitter account.
