"China and Russian Federation have been showing a united front on North Korea for the past several months".
Also today, Russian lawmakers who visited Pyongyang said North Korea was not prepared to disarm.
"We have got to take them at their word, so this could be a global conflict".
"If the United States drops out of this deal, it won't be very credible in the eyes of those who are now requested to drop their (own) nuclear program like North Korea", Lavrov said. "We regard this negatively", he said.
While saying "our hopes are that China will show leadership and follow through", Ms Haley also issued a warning: "China can do this on its own, or we can take the oil situation into our own hands". Explaining the importance of an oil embargo, she said that when China cut off oil supplies to that country in 2003, Pyongyang came to the negotiating table. The regime has claimed it can now strike the entire USA mainland with a "super-large heavy warhead".
U.S. President Donald Trump said in October he would not certify that Tehran was complying with the 2015 deal and warned he might ultimately terminate it, accusing Iran of "not living up to the spirit" of the accord.
"Japan will never tolerate a nuclear-armed North Korea", the country's Permanent Representative Koro Bessho said.
China provides about 90 percent of North Korea's energy needs and previous year shipped around 6,000 barrels per day to Pyongyang.
In its response to the USA request for an embargo, the Chinese Foreign Ministry said the country had "always implemented full, comprehensive, serious and strict resolutions".
Trump kept the war of words going while speaking at a meeting in Missouri ridiculing Kim as a "sick puppy" and "little rocket man".
He also complained that the United States was "totally ignoring" a U.N. demand for talks with North Korea.
