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.
"We have to protect ourselves with respect to China, Russia and even the United States", he told France's Europe 1 radio.
Mr. Trump and Macron's early relationship was marked by kisses, frequent meetings and marathon power handshakes.
"When I see President Trump announcing that he's quitting a major disarmament treaty which was formed after the 1980s euro-missile crisis that hit Europe, who is the main victim?"
Macron told Europe 1 radio that the "main victim" of the U.S. withdrawal from the INF accord was Europe and its security.
"We need a Europe which defends itself better alone, without just depending on the USA".
The US president tweeted after arriving in Paris ahead of an worldwide commemoration of the 100th anniversary of the armistice that ended the First World War. Since the beginning of his term, Trump has been urging US NATO allies in Europe to up their defense spending.
However, on other occasions, Trump has said that the US remains committed to North Atlantic Treaty Organisation despite concerns over its funding.
Trump has criticized existing European tariffs and regulations on autos, and has said he believes it's unfair that barriers are higher for American auto manufacturers seeking to sell in Europe.
The Trump administration reimposed sanctions on Iran over European opposition, blacklisting hundreds of Iranian firms and individuals.
But the relationship-building failed to persuade Trump to remain in the global climate change agreement or Iran deals and did nothing to protect France from United States tariffs.
"Great world leaders", he said, are "driven by national interests".
