After Pyongyang's most recent missile launch a Hwasong-15 missile on Wednesday, Trump responded with an uncharacteristically restrained "We'll handle [it]" before returning to his typical rhetoric, calling North Korean leader Kim Jong Un a "sick puppy" at a rally in Missouri.
In a tit-for-tat war of words with Korean leader Kim Jong-un, the United States president called Kim a "madman" while the Korea leader dubbed him a "mentally deranged USA dotard".
Tillerson's remarks echo those made on Wednesday by US Ambassador to the UN Nikki Haley, who stressed that the nations of the world "have it within our power to further isolate, diminish and, God willing, reverse the risky course of the North Korean regime".
"The recent US actions seemed to be deliberately aimed at provoking Pyongyang to take new sharp actions", Lavrov said, according to a Russian Foreign Ministry statement.
Mr Trump has been trying to apply more pressure on the hermit kingdom and re-designated them a state sponsor of terrorism, meaning the U.S. can enforce even more sanctions on Kim Jong-un's regime. "We're really asking them to please restrain more of the oil, not cut it off completely", Tillerson said in remarks at the State Department.
"We were encouraged by that approach, but suddenly they are conducting surprise military exercise in October, then November, now we announced in December", - said the Minister.
"China and Russian Federation have been showing a united front on North Korea for the past several months". The U.S. already imposed unilateral sanctions on Pyongyang, but these seem to have failed to make any difference in the regime's plans for turning into a nuclear power. Both countries, he said, are "concerned that the USA has not offered a diplomatic option", which increases the possibility of war, "and that would be a catastrophe for the whole region".
"The Chinese are doing a lot".
He said: "North Korea will be unsafe in about nine months or so because then two things are going to happen at the same time".
The latest threat came after North Korea tested its third ICBM, which it claimed was capable of striking anywhere in the United States.
North Korea has been accelerating its threat to the USA and to the globe with recent missile tests. It was not Germany's desire to shut down its embassy, he said, but added: "that doesn't mean we are ruling it out".
