Trump sent a tweet calling Macron's proposal "very insulting" as the USA president's plane landed Friday evening for celebrations with world leaders commemorating the 100th anniversary of the end of World War I.
"Very insulting, but perhaps Europe should first pay its fair share of North Atlantic Treaty Organisation, which the USA subsidizes greatly!" tweeted Trump, who is scheduled to meet Macron for bilateral talks on Saturday.
Earlier this week, Macron said in an interview with Europe 1 that he wanted "a real European army" to protect the Europeans from the US and other nations.

The two leaders are expected to discuss European concerns about Trump's plans to withdraw the U.S. from the Intermediate-Range Nuclear Forces (INF) treaty and renewal of United States sanctions against Iran.

Mr Trump's brief visit to Europe comes amid uncertainty about the USA relationship with the continent.
Trump's talks with Macron at the Elysee are likely to cover European concerns about Trump's plans to withdraw the United States from the 1980s Intermediate-Range Nuclear Forces Agreement and US renewal of sanctions against Iran.
