France’s foreign minister said on Wednesday that Donald Trump’s verbal jousting with North Korea was perhaps not the best method to handle the nuclear crisis.

 He urged the U.S. president to focus his attention on raising diplomatic pressure on Pyongyang.

Bellicose statements by Trump and North Korean leader Kim Jong Un in recent weeks have created fears that a miscalculation could lead to action with untold ramifications, particularly since Pyongyang conducted its sixth and most powerful nuclear test on Sept. 3.

“Trump’s method is perhaps not the best, but at the same time we shouldn’t mix up the responsibilities,” Jean-Yves Le Drian told BFM TV. “The country that is breaking with nuclear international agreements is North Korea. President Trump is reacting forcefully to this, but without a doubt there is a way to act in a different way by putting pressure and sanctions.”
