German Foreign Minister Sigmar Gabriel unleashed a volley of criticism against  Donald Trump, slamming his "short-sighted" policies that have "weakened the West" and hurt European interests, Telegraph reported.

The sharp words from Sigmar Gabriel came after Trump concluded his first official tour abroad, which took him to Saudi Arabia, Israel, Brussels and then Italy for a G7 summit, where he refused so far to sign up to upholding the 2015 Paris climate accord.

Gabriel said that "anyone who accelerates climate change by weakening environmental protection, who sells more weapons in conflict zones and who does not want to politically resolve religious conflicts is putting peace in Europe at risk". 

"The short-sighted policies of the American government stand against the interests of the European Union," he said, judging that "the West has become smaller, at least it has become weaker".

"We Europeans must fight for more climate protection, fewer weapons, and against religious [fanaticism], otherwise the Middle East and Africa will be further destabilised," Gabriel said.
