US Permanent Representative Nikki Haley, who piloted Resolution 2371 on Saturday, called it "the most stringent set of sanctions on any country in a generation".
The US-drafted resolution includes the strongest sanctions ever imposed in response to a North Korean ballistic missile test and targets its main exports, slashing their annual revenue by $1 billion.
The sanctions were a triumph for the U.S. that came after Haley worked strenuously to get a reluctant Beijing to agree to further tightening the restrictions on Pyongyang.
The U.N. Security Council unanimously approved tough new sanctions on North Korea on Saturday including a ban on exports worth over $1 billion - a huge bite in its total exports, valued at $3 billion past year.
Thornton says the USA wants to ensure that with the new sanctions, there's "not this kind of episodic back and forth that we've seen". It would also prohibit countries from increasing the current numbers of North Korean laborers working abroad، ban new joint ventures with North Korea and any new investment in current joint ventures. Ahead of Tillerson's trip, the top American diplomat for Asia said the US was expecting a "general chorus of condemnation of North Korea's provocative behavior" as well as "pretty serious diplomatic isolation directed at the North Korean foreign minister".
A resolution needs nine votes in favor، and no vetoes by the United States، China، Russia، France or Britain، to be adopted.
For the US, it was a long-awaited sign of progress for Trump's strategy of trying to enlist Beijing's help to squeeze Pyongyang diplomatically and economically.
North Korea has already faced a decade's worth of ever-increasing sanctions backed by the USA and its allies. Washington has threatened to exert trade pressure on Beijing and impose sanctions on Chinese firms doing business with Pyongyang. China has long called for a two-way freeze in which North Korea would halt nuclear development, while the US would stop joint military exercises with South Korea that Pyongyang views as rehearsals for a future invasion.
"We had tough negotiations this week", Haley told reporters. Susan Thornton, the top US diplomat for Asia, said Beijing had historically cooperated with sanctions after flagrant North Korean violations but then slipped back over time. Kang is thanking the USA for consulting with South Korea on the sanctions.
"We are not hostages to our relations when we have to work together on issues which are far more important than our bilateral relations low", Nebenzia told Reuters.
The proposed resolution would also add nine North Koreans, mainly officials or representatives of companies and banks, to the United Nations sanctions blacklist, banning their travel and freezing their assets. Chinese Foreign Minister Wang Yi, meeting with North Korea's top diplomat during the gathering in Manila, urged the North to "maintain calm" despite the United Nations vote. The diplomat said it was hard to estimate how much North Korea was earning from sending workers overseas.
Aside from the United Nations, the ARF was the only venue where the global community, including Southeast Asian countries, could reach North Korea, a Philippine official said recently.
China is the primary customer for the North's exports, and it will now have 30 days to pass legislation to implement the new resolution and cease imports of North Korean iron, lead, and seafood.
