"We also noted that many country leaders also said the Korean peninsula issue should be peacefully resolved and the call for dialogue, peace and deescalation, rather than confrontation, war and mutual provocation, represents the common voice of the worldwide community".
Singapore's Ministry of Foreign Affairs said USA authorities had informed them prior to the designations and it was investigating.
"We strongly urge the U.S.to immediately correct its mistake, so as not to impact bilateral cooperation on relevant issues", a spokesperson of the Chinese Embassy in Washington said in an email. But he later expressed frustration with North Korea's key ally China, saying the USA would use the tools at its disposal to increase pressure on the North.
"I think it is worth noting that we have had no missile launches or provocative acts on the part of North Korea since the unanimous adoption of the UN Security Council resolution", Tillerson said. That suggested his intent was to give Kim Jong Un's regime an opening and a signal.
"As long as the United States hostile policy and nuclear threat remains unchallenged, (North Korea) will never place its self-defensive nuclear deterrence on the negotiating table or step back an inch from the path it took to bolster the national nuclear force", Mr Ju said.
"Perhaps we are seeing our pathway to sometime in the near future having some dialogue..."
GENEVA-North Korea and the United States accused each other on Tuesday of posing a nuclear threat, with Pyongyang's envoy declaring it would never put its atomic arsenal up for negotiation.
That led to particularly belligerent rounds of threats from North Korea state media and President Trump, who at one point vowed "fire and fury" against North Korea and then warned that US military weapons were "locked and loaded".
The North warned on Sunday that it would launch a nuclear war if the annual US-South Korea military exercises this week turn to "actual fighting".
Tensions escalated further when U.S. President Donald Trump threatened to unleash "fire and fury" on Pyongyang, and the regime responded with threats to fire ballistic missiles towards the U.S. territory of Guam.
The sanctions also targeted six individuals - four Russians, one Chinese and one North Korean.
Kim Jong Un vanished from the public eye for about two weeks this month after his country launched a ballistic missile capable of reaching parts of the U.S. Now government sources have disclosed where the North Korean leader went: the border with South Korea.
The spokesman also said South Korea always stands prepared against the possibility of North Korea's strategic provocations, warning North Korea against pushing ahead with any provocations, including nuclear or long-range missile tests.
Vincent Brooks, commander of U.S. Forces Korea, says the allies should continue the war games until they "have reason not to".
Since at least 2013, South Korea has been building a program known as Kill Chain that is aimed at detecting signs of imminent missile and nuclear attacks from the North with the help of American spy satellites, and, if necessary, neutralizing its weapons with pre-emptive strikes.
Sanctions were imposed on Chinese individuals and companies for allegedly supporting North Korea's nuclear programme.
