He warned Australia could be struck by a North Korean weapon.
The U.S. said it welcomed Moscow's efforts, even though the Russian-Chinese roadmap proposes an end to the U.S joint military exercises with South Korea in exchange for Pyongyang giving up on the nuclear development programme-a proposal the U.S. has already rejected.
The Russian Foreign Ministry made the announcement in a statement issued on Friday after a meeting between Russian ambassador-at-large Oleg Burmistrov and Choe Son-hui, director-general of the North American department of North Korea's Foreign Ministry.
The ministry's Mikhail Ulyanov said the country was working "behind the scenes" to find a political solution, but admitted the use of sanctions against North Korea is nearly exhausted.
Russian Federation might be trying to get involved in back-channel diplomacy between Pyongyang and Washington, the sources said.
Rep. Woo Sang-ho, a former floor leader of the ruling Democratic Party, also said in a radio interview that military tensions on the peninsula are at the highest-level since the Korean War and the recent USA flying of U.S. B-1B Lancer bombers near the North fueled the tensions.
Last week, in his first speech to the UN General Assembly, Mr Trump vowed to "totally destroy" North Korea if it continued to threaten the United States and it allies.
"There needs to be a mediator between both sides in order to prevent conflict".
North Korea's growing interactions with Russian Federation include a visit from Burmistrov to the North from July 22 to 25, which according to KCNA, was meant to discuss Korean Peninsula issues.
Choe's visit is seen as part of Russia's attempts to play a bigger role in resolving North Korea's nuclear standoff. North Korean leader Kim Jong Un threatened retaliation in his response, calling Trump "mentally deranged" and a "dotard".
Russian President Vladimir Putin has said before that his country, which shares a border with North Korea, cannot accept the possibility of a nuclear North Korea but acknowledged that the current standoff could not be resolved by sanctions alone.
The new UNSC resolution was supported by Moscow and also by Beijing, the North's largest communist ally.
