French President Emmanuel Macron urged Donald Trump on Thursday not to take any hasty decisions on a global climate change deal that the U.S. president threatened during his election campaign to abandon.

Macron and Trump also discussed the Syrian crisis, counterterrorism and defense spending over lunch at the U.S. ambassador's residence in Brussels, their first meeting since Macron was elected on May 7 after a turbulent campaign.

Macron, a centrist, described their conversation as warm and pragmatic but also said it had been "extremely direct and very frank," acknowledging there were subjects where the two leaders did not necessarily see eye-to-eye.
