Mr. Trump's national security adviser, John Bolton, said Friday in Paris that the USA was concerned about stability in Europe and that Mr. Trump was not shirking from global engagement.
"During his visit to Paris, President Buhari will attend a luncheon hosted by President Emmanuel Macron of France in honour of visiting heads of delegations". As he arrived, Mr. Trump tweeted that Macron "has just suggested that Europe build its own military in order to protect itself from the U.S., China and Russian Federation".
Trump's reaction is likely to add to strains in transatlantic relations, which will be under the spotlight this weekend as 70 world leaders, including German Chancellor Angela Merkel and Russia's Vladimir Putin, gather in Paris to mark the centenary of the end of World War 1.
He added instead of building a military, Europe should first pay its fair share of North Atlantic Treaty Organisation costs noting the US pays far more than any other member.
Trump's official mission on the trip is to participate in ceremonies marking the 100th anniversary of the end of World War One.
The US President is hoping to move past post-midterms controversy after the White House was accused of doctoring footage in support of its decision to revoke the press credentials of CNN reporter Jim Acosta.
Trump is set to meet with Macron Saturday morning at the Élysée Palace in Paris, per USA Today.
Mr. Trump and Macron's early relationship was marked by kisses, frequent meetings and marathon power handshakes.
Mr Trump's brief visit to Europe comes amid uncertainty about the USA relationship with the continent.
The White House and the Kremlin had previously considered a formal meeting in Paris. "I think the enduring lesson (of World War I) for the United States is that when you become a global power. you have global interests to protect", Bolton said. "Europe and its security", the French president said.
The statement reads in part, "The Nigerian President will join the United Nations Secretary-General, Antonio Guterres and other world leaders in discussing contributions towards global peace while underscoring the imperative of collective action".
Macron and other European leaders have repeatedly criticized Trump's efforts to undermine the deal, and have sought to create a special mechanism that would allow the bloc to avert USA sanctions and continue trading with Iran.
The French president, who tried but failed earlier this year to talk Trump out of withdrawing from the 2015 Iran nuclear deal, has also voiced worries about the impact of sanctions on European companies doing business with Iran.
