U.S. President Donald Trump and North Korea's leader Kim Jong Un shake hands during their summit at the Capella Hotel on Sentosa island in Singapore June 12, 2018.

The Kremlin said on Wednesday that a summit between U.S. President Donald Trump and Kim Jong Un showed Russian President Vladimir Putin had been right to advocate direct dialogue as the only way of reducing tensions with North Korea.

Kremlin spokesman Dmitry Peskov told reporters on a conference call that the summit, held in Singapore on Tuesday, had helped reduce tensions on the Korean Peninsula.

But he said it would have been wrong to have expected that all of the issues surrounding North Korea's missile and nuclear program could have been solved in an hour.

"We still need to analyze the results of the meeting," said Peskov. "But the fact that it took place can only be welcomed. Such meetings help ease tensions and move us away from the critical point reached several months ago."
