"[This] will lead to no good", Putin said.
The officials spoke on condition of anonymity, citing department rules.
The reports followed South Korean defence ministry statements on Monday that the North was preparing more missile tests. No mention was made of other retaliatory measures, such as the possible use of force.
Russian President Vladimir Putin - accused of helping install Donald Trump as president of the U.S.by waging a cyberwar against Trump's campaign opponent, Hillary Clinton - has downplayed questions that he's grown frustrated with the current American leader.
The White House on Wednesday released details of calls Tuesday with British Prime Minister Theresa May and Australian Prime Minister Malcolm Turnbull. Trump has threatened to cut off trade with all countries that do business with North Korea, a group that includes China.
Either way, it's too risky to assume North Korea is bluffing. "Discussions also took place on the promotion of tourism between the two countries and also on the student exchange between the two sides", Kumar said.
"Because the Americans are sending mixed signals, Putin probably sees an opening to take the lead", he said.
Then, on Sunday, the USA seized control of three diplomatic posts - in San Francisco, Washington DC and New York City, forcing out Russian workers.
The country conducted two nuclear tests past year alone, the second being its most powerful in history.
Meanwhile, North Korea's ambassador to the United Nations in Geneva, Han Tae-song, said his country's recent "self-defence measures" were a "gift package addressed to the US".
During the Security Council meeting, China's ambassador Liu Jieyi warned that the crisis was worsening and emphasised the need for dialogue and a diplomatic solution. "We must seek cooperation projects aimed at ensuring peace and prosperity not only on the Korean Peninsula and the Far East, but also in Northeast Asia and Eurasia", he said, according to a copy of the written interview released by his presidential office Cheong Wa Dae.
President Vladimir Putin said on Monday that even though North Korea possess a nuclear arsenal, sanctions against Pyongyang are useless.
They have raised worries over rumored health hazards linked to the system's powerful radar and the possibility that the town will become a target of North Korean attacks.
He said the nuclear test was a serious violation of U.N. Security Council resolutions, but reaffirmed his commitment to the peaceful resolution of the issue. He said it "offers a genuine way to defuse the tensions and a step-by-step settlement".
While it's not clear how - and if - the North Korea issue will be resolved, the United States has flatly rejected a Chinese proposal, backed by Russian Federation, for a suspension of hostilities on both sides.
Two days after Pyongyang's biggest nuclear test to date, South Korea's navy held major live- fire drills on Tuesday to warn the North against any provocations at sea. If they are removed from the equation, Putin said, Russian Federation has fewer than 455 diplomats in the United States. The U.S. Embassy in Russian Federation was asked to reduce its embassy and consular staff to 455.
North Korea's sixth and most powerful nuclear test "torpedoes the global non-proliferation regime, violates UN Security Council resolutions and worldwide law, and creates a threat for regional peace and stability", Putin said in a phone call with Japanese Prime Minister Shinzo Abe, according to the Kremlin.
Putin while speaking this morning at a news conference at the BRICS summit in Xiamen, China said, "It's "naïve" to ask whether I'm disappointed in the US leader because he's not my bride, and I'm also not his bride or groom".
Putin reportedly said that the USA government was acting like bullies, and that technically, of those 455 Americans, 155 of them are working with the United Nations.
