The new draft imposes a full ban on textile exports, a biting new sanction that some diplomats fear may lead to an abstention by China.
The latest resolution caps North Korea's imports of refined and crude oil at 8.5 million barrels a year, which represents a 30 percent cut, according to Nikki Haley, the US ambassador to the United Nations.
North Korea has responded with the usual bluster.
Another senior administration conceded the new sanctions would not be enough in themselves to change North Korea's behavior, but would help measure compliance with United Nations restrictions by other countries. "This threat is what unites us in the security council and, I hope, what will bring us towards unity when it comes to the vote and hopefully beyond".
Nothing screams for the necessity of such a move like North Korea's response to the UN vote: On Tuesday, it warned that the United States would "suffer the greatest pain".
Royce said Washington did not need Beijing's cooperation to increase pressure on North Korea.
The US wanted a complete ban on oil exports to North Korea, immediate end to employment of an estimated 93,000 of its citizens overseas, forcible boarding of ships trading with that country to check for contraband, and restrictions on UN.
North Korea says the US will pay "due price" for spearheading the U.N.'s effort to impose new sanctions against the regime.
Flynn allegedly failed to disclose trip to broker Saudi-Russian business deal
Michael Flynn , President Donald Trump's disgraced former national security adviser, may be in even more legal hot water. In response, officials from the U.S. companies provided statements to the Democrats, confirming Flynn's trip in 2015.
On September 3rd Mr Kim provoked global outrage with a test of what North Korea claimed was a hydrogen bomb.
The pipeline, also called the Friendship Oil Pipeline, runs for more than 30 km from storage facilities in the Chinese border city of Dandong to an oil depot in Sinuiju in North Korea. Almost 80 percent of the textile exports went to China.
The US official said the ban on textile exports would deprive North Korea of some 726 million in annual revenue. "We are urging the North to end the vicious circle of repeating provocations and sanctions and start a dialogue for the peaceful resolution of its nuclear issue", he added.
"Today's resolution would not have happened without the strong relationship that has developed between President [Donald] Trump and Chinese President Xi".
Among the provisions that were in a draft proposal, but not the final resolution were a total oil embargo and a freeze on the assets of both North Korean leader Kim Jong Un and the national airline.
Joint ventures will be banned and the names of senior North Korean official and three entities were added to a United Nations sanctions blacklist that provides for an assets freeze and a global travel ban. This is clearly different from the course pursued by South Korea and the United States of placing additional pressure on North Korea.
Russian Ambassador Vassily Nebenzia told the council it would be a "big mistake to underestimate this Russia-China initiative" for a so-called freeze-for-freeze, adding that Moscow would "insist on it being considered".
"First of all, these are significantly tougher sanctions". The U.N. only started hitting whole sectors of the North Korean economy a year ago, and textiles is the latest.
