The U.N. Security Council expanded targeted sanctions against North Korea on June 2.
This is the first such resolution agreed by the U.S. and China, Pyonyang’s only major ally.
The sanctions come after the North launched repeated missile tests.
President Trump had pressured China to take more action to rein in its neighbor.
Beijing and Washington negotiated for five weeks to draw up a resolution.
More North Korean names were added to the U.N. blacklist, which meant a global travel ban and asset freeze.
The resolution, adopted unanimously by the 15-member council, targets four North Korean entities and 14 people.
The entities include including the Koryo Bank and Strategic Rocket Force of the Korean People’s Army.
North Korea’s Koryo Bank handles overseas transactions for Office 38, a shadowy body that manages the private slush funds of the North Korean leadership, according to a South Korean government database.
The people include the head of Pyongyang’s overseas spying operations.
The measures adopted on Friday could have been agreed by the council’s North Korea sanctions committee behind closed doors, but Washington convinced China to back a public vote on the blacklist, amplifying the council’s unhappiness with Pyongyang’s defiance of a U.N. ban on ballistic missile launches.
