Washington and its allies have said there is a growing urgency for China, North Korea's top ally and trading partner, to apply more pressure on its already isolated neighbor to get it to back down on its nuclear weapons and missiles programs.
But today Pyongyang's ambassador, Han Tae Song, told a conference in Geneva: 'My delegation condemns in the strongest terms and categorically rejects the latest illegal and unlawful U.N. Security Council resolution'.
The sanctions caps oil exports, bans all textile exports, restrict future employment of North Koreans overseas, allow countries to inspect ships going and coming from North Korea but without using force, and add more weapons-related items and technologies to the list of items prohibited for transfer to Pyongyang.
On Monday, the UNSC, however, condemned Pyongyang for its "flagrant disregard" of its previous resolutions, and demanded that it immediately suspend its ballistic missile and nuclear programmes. In June, the U.S. designated the Bank of Dandong, a regional Chinese bank, as a "primary money laundering concern" over its alleged help to North Korea in accessing the United States and worldwide financial systems. "We now have more tools in our toolbox and we will continue to use them to put additional sanctions on North Korea until they stop this behavior".
"The DPRK is ready and willing to use any form of ultimate means", the statement said, referring to the country by its acronym.
The statement also said that the sanctions "verify that the road [North Korea] chose to go down was absolutely right and to strengthen its resolve to follow this road at a faster pace without the slightest diversion until this right to finish is over".
The sanctions are aimed at curtailing North Korea's cash flow, in the hope of putting a halt to their nuclear and missile programs.
On September 3, Pyongyang tested what it claimed was a hydrogen bomb in the most powerful nuclear test conducted by the country so far.
US Ambassador Nikki Haley welcomed the sanctions and said that this was a message to the recluse nation that "the world will never accept a nuclear-armed North Korea".
"We think it's just another very small step - not a big deal", Mr Trump said as he met with Malaysia's prime minister at the White House.
Sustaining a tough tone in the face of North Korea's missile and nuclear weapons tests, Trump indicated that he would continue to press for sanctions created to make the regime recalculate its strategy.
The US is calling for an oil embargo on the North, an assets freeze on Kim Jong-Un, a ban on textiles and an end to payments of North Korean guest workers. A tougher initial United States draft was weakened to win the support of Pyongyang ally China and Russian Federation.
Both countries have called for the Security Council to move away from sanctions, and, instead, focus on a return to the negotiating table via the Six Party Talks. The council banned North Korean textile exports, an important source of hard currency, and capped its imports of crude oil, although the sanctions were not as harsh as the US had hoped.
On Sunday, North's Foreign Ministry spokesman said the U.S. was "going frantic" to manipulate the UNSC over the nuclear test, which he claimed was part of his country's "legitimate self-defensive measures". U.S. Ambassador Nikki Haley warned that Pyongyang, North Korea's capital city, was "begging for war" and spearheaded a fast-paced diplomatic response by pushing for United Nations action with a one-week timetable.
The unique circumstances surrounding North Korea's stubborn pursuit of nuclear weapons stands in stark contrast to the fate of other would-be developers like Syria and Iraq, countries that found their embryonic facilities quickly obliterated in Israeli air strikes.
The New York Times quoted Washington-based executive director Daryl Kimball of the Arms Control Association as saying: "There is no only-sanctions strategy that will bring the North Koreans to heel".
Chinese envoy Liu Jieyi said that the United States must not try and change the situation by using military force and that "China will continue to advance dialogue", reported the New York Times.
The world body banned North Korean textile exports on Monday, an important source of hard currency, and capped its imports of crude oil.
