U.S. President Donald Trump said on Friday it was "very insulting" for French President Emmanuel Macron to suggest Europe should create its own army to protect itself from potential enemies, including the United States.
"Very insulting, but perhaps Europe should first pay its fair share of North Atlantic Treaty Organisation, which the U.S. subsidizes greatly!", he added.
On Saturday morning, the United States president arrived at the Elysee Palace under rainy skies for talks with Macron.
"I don't know that we're seeing each other in Paris, but we may", Mr Trump said.
Mr. Trump's national security adviser, John Bolton, said Friday in Paris that the US was concerned about stability in Europe and that Mr. Trump was not shirking from global engagement.
Faced with "a Russian Federation which is at our borders and has shown that it can be a threat", Macron said, "We need a Europe which defends itself better alone, without just depending on the United States, in a more sovereign manner".
The U.S. leader has traveled to Europe with first lady Melania Trump to participate in a ceremony Sunday to mark the 100th anniversary of the armistice that ended World War I, in which 40 million people were killed.
Mr Macron said on Tuesday that Europe "had to protect itself".More news: Backstage at the 2018 Victoria's Secret fashion show

The US leader had taken to Twitter moments after getting off the plane in the French capital to say Macron's plan for a European military was 'insulting'.
Trump has made similar arguments, particularly in urging NATO's European members to increase its share of defence spending.
President Donald Trump is assuring that the United States will "help" with European defense but repeated his insistence that nations on the continent pay their fair share.
He is also overseeing the formation of a European rapid reaction force, a nine-country endeavour much smaller than an actual army, which is backed by Germany and the UK.
Some 70 leaders will gather at 11 am on Sunday local time at the tomb of the Unknown Soldier at the Arc de Triomphe, in Paris, to mark the 100th anniversary of the end of the First World War. Trump and first lady Melania Trump will also visit the American cemetery in Belleau, France, to pay their respects to US soldiers who died on French soil during the war. "And whichever way we can do it the best and most efficient would be something we both want", Trump said.
After his meeting with Macron, Trump was scheduled to head to the battlefield of Belleau Wood, 55 miles northeast of Paris.
The president, joined by his wife Melania and high-ranking United States officials, arrived late on Friday aboard Air Force One for a visit that he called "very special" and one that he "looked forward to". "There may be a lunch for the leaders".
