Austrian Chancellor Sebastian Kurz said that under President Donald Trump, the United States can no longer be considered reliable.

His comments came in an interview with the Financial Times.

"The U.S. has become more and more unreliable for us," he said. "The most important thing is that Europe has to remain united."

In July, Austria will take over the European Union's rotating presidency.

In the past, he said, the E.U. has "wasted time" on divisive issues.

"We need to shift our focus from the debates about redistributing refugees within the E.U., and should concentrate more on external border protection," he said.

The Financial Times noted that Russian President Vladimir Putin is scheduled to visit Austria next month.

"We won't be able to solve the crisis in Ukraine alone . . . Syria, we will only be successful if we find a way to act united with the U.S. and Russia, so I think it's not negative for the E.U. if countries like Austria — which has always been a bridge-builder — has . . . a good relationship with Russia," Kurz said.

Meanwhile, RT.com noted concerns about the Trump administration have been increasing throughout the EU in recent months.

It noted a poll showed 82 percent of Germans say the U.S. is not a reliable political partner.

It maintained the first rift was sparked when Trump withdrew from the Paris climate agreement. And it said concerns increased when Trump withdrew from the nuclear agreement with Iran and recognized Jerusalem as the capital of Israel.
