Russia on Monday said countries should exercise restraint in dealing with North Korea following President Trump's comments on the threat from Pyongyang.

“Moscow has called and continues to call on the parties involved in the conflict and on those who have anything to do with this issue to exercise restraint and to avoid any steps that would only worsen the situation," Kremlin spokesman Dmitry Peskov told reporters, according to Reuters.

His comments come after Trump said Saturday "only one thing" would rein in North Korea's nuclear and missile development programs.

"Presidents and their administrations have been talking to North Korea for 25 years, agreements made and massive amounts of money paid hasn't worked, agreements violated before the ink was dry, makings fools of U.S. negotiators," Trump tweeted Saturday.

"Sorry, but only one thing will work!"

North Korean leader Kim Jong Un on Saturday dubbed his country's nuclear weapons program a "powerful deterrent" that guarantees its sovereignty.

On Monday, Trump reiterated that the U.S. policy toward North Korea hasn't worked for 25 years.

"Our country has been unsuccessfully dealing with North Korea for 25 years, giving billions of dollars & getting nothing," Trump tweeted. "Policy didn't work!"
