The United Nations Security Council unanimously imposed new sanctions on North Korea on Saturday that could slash its $3 billion annual export revenue by a third.

"The North Korean program remains an unconstrained one with neither sanctions nor an operational diplomatic agreement holding it back", John Park, the director of the Korea Working Group at Harvard Kennedy School, told Bloomberg News.
The minister also praised the remarks of US Secretary of State Rex Tillerson, after the US made a series of guarantees including it did not seek a regime change in North Korea or an accelerated reunification of the Korean peninsula.
"We will, under no circumstances, put the nukes and ballistic rockets on negotiating table", North Korea said. China and Russian Federation voted with us.
Chinese Foreign Minister Wang Yi has urged North Korea to act "smart", following the imposition of harsh sanctions on Pyongyang by the United Nations Security Council (UNSC), which includes North Korean ally Beijing.
On Sunday, following a late-night conversation with South Korean President Moon Jae-in, Trump tweeted: "Just completed call with President Moon of South Korea". A page-one editorial (link in Chinese) in the overseas edition of the state-run People's Daily argues the US and South Korea should suspend military exercises in the area.
The Trump administration cautiously embraced China's apparent newfound cooperation, while putting it on notice that the US would be watching closely to ensure it didn't ease up on North Korea if and when the world's attention is diverted elsewhere.
On Thursday in Bedminster, New Jersey, where he is on a working vacation, Trump also declared the US nuclear arsenal "in tip-top shape, and getting better, and getting stronger".More news: US stocks slip amid heightened US-North Korea tensions

"If it believes it is only North Korea rather than the USA and South Korea as well to blame for the nuclear issue, this ill-fitting mindset will not help solve the crisis", it said.
"Owing to China's traditional economic ties with North Korea, it will mainly be China paying the price for implementing the resolution", a statement from the Foreign Ministry cited Wang as saying.
"President Moon and president Trump shared concerns over North Korea's evolving nuclear capabilities, and agreed their countries must put maximum pressure and sanctions on North Korea under cooperation with the global community to have North Korea give up its nuclear and missile programmes, and choose the right path", said Mr Park.
Earlier this month, the White House moved to start investigating China's trade practises, in what many saw as retaliation for their perceived inaction on North Korea.
With a newfound ability to turn rhetoric into reality, the US and its global partners can expect additional provocations from the extremely hostile North Korean regime.
"Do not violate the U.N.'s decision or provoke worldwide society's goodwill by conducting missile launching or nuclear tests", Wang said, in an unusually direct admonition.
The test added pressure to an already tense situation with isolated North Korean dictator Kim Jong-un. Trump has said he will not allow Pyongyang to develop a nuclear weapon capable of hitting the United States.
So far, outsourcing its North Korea policy to China has not worked for the United States.
