But the atmosphere is likely to worsen again next week when the United States and South Korea kick off their annual Ulchi Freedom Guardian military drills.
"Military adventures and threats of force [are] unacceptable", the Russians added.
Tillerson says: "We continue to be interested in trying to find a way to get to dialogue but that's up to him".
"If nuclear North Korea chooses to self-detonate as it will fail anyway, what will South Korea do?" the experts often respond. It did not identify which media.
Lt. Gov. Ray Tenorio told the media Tuesday that North Korea appears to be holding off on an imminent launch of missiles into waters near the USA territory in the Pacific. State media reported that leader Kim Jong Un was watching US moves before deciding to order the test.
He added that there is no change in Guam's threat assessment, and that the island is operating as usual.
Referring to North Korean leader Kim Jong Un, Trump also told reporters, "If he does anything with respect to Guam or any place else that's an American territory or an American ally, he will truly regret it".
"The south authorities' utterances about improving intra-Korean ties turned out to be nothing but hypocrisy", it said.
Trump said nothing about North Korea during a raucous 25-minute exchange with reporters at Trump Tower in NY.
South Korean President Moon Jae In said Tuesday no military action on the Korean Peninsula is possible without his country's approval and urged peaceful resolution of the crisis over North Korea's nuclear and missile programs.
"I call upon the North Korean government: without global cooperation and co-existence economic development is impossible", said Moon.
Moon, elected to replace impeached president Park Geun-Hye, came into office in May and has since had to deal with tensions over the North's missile and nuclear programmes. But it also reported that leader Kim Jong Un would watch US conduct before giving his orders for the test. Both Koreas and the United States have signalled in recent days, however, a willingness to avert a deepening crisis, with each suggesting a path toward negotiations.
Moon Jae-in, a liberal who favors engagement with the North, delivered a nationally televised speech Tuesday on the anniversary of the end of World War II and the Korean Peninsula's liberation from Japanese colonial rule. But its comments appeared to signal a path to defuse the crisis by saying Kim would watch USA conduct before giving his orders. This would involve negotiating with the U.S. to redeploy some of its own nuclear weapons to the country.
Tensions have since eased with the North's leader Kim Jong-Un saying he would watch the "Yankees" for a time before deciding whether to proceed with the Guam plan.
"The urgent task is to slam the brakes on the mutually provocative words and actions between North Korea and the United States", the Chinese statement said.
Gen. Joseph F. Dunford Jr., chairman of the Joint Chiefs of Staff, has visited Tokyo, Seoul, and Beijing this week in an effort that he said was aimed at finding a diplomatic, not a military, solution.
Last week it threatened to send a salvo of rockets towards the US territory of Guam - although it appears to have backed off for now - while US President Donald Trump promised "fire and fury" and said that Washington's weapons were "locked and loaded".
