The eurozone's chief finance minister said his "confidence" in President Donald Trump's White House was growing, as the administration appeared to be "more realistic and sensible," The Hill reported Saturday.

"I would be lying if I say I'd be free of worries. So, yes, I worry about it," Jeroen Dijsselbloem, Dutch minister of finance, told CNBC on Saturday. "Yet the Trump government seems to become more realistic and sensible. So, let's put out confidence in that."

Should Trump's policies continue to have a more nationalistic rather than globalist focus, Dijsselbloem said it could open the door to other countries taking the lead on the world stage.

"If the Americans no longer lead the free world, then the Europeans should consider taking that lead," he said.

Dijsselbloem heads the Eurogroup, the economic body of the European Union which consists of countries for which the euro is their official currency.
