The UN Security Council has expanded targeted sanctions against North Korea after its repeated missile tests.
The council has adopted the first such resolution agreed by the United States and Pyongyang's only major ally China since President Donald Trump took office.
The Trump administration has been pressing China aggressively to rein in its neighbour, warning that all options are on the table if Pyongyang persists with its nuclear and missile development programmes.
The United States has struggled to slow those programmes, which have become a security priority given Pyongyang's vow to develop a nuclear-tipped missile capable of hitting the US mainland.
"The United States will continue to seek a peaceful, diplomatic resolution to this situation," US Ambassador to the United Nations Nikki Haley told the council after the vote.
But she added: "Beyond diplomatic and financial consequences, the United States remains prepared to counteract North Korean aggression through other means, if necessary."
Adding names to the UN blacklist - a global travel ban and asset freeze - was the minimum sanctions measures the Security Council could have taken and comes after five weeks of negotiations between Washington and Beijing.
"The Security Council is sending a clear message to North Korea today - stop firing ballistic missiles or face the consequences," Ms Haley said.
The resolution, adopted unanimously by the 15-member council, sanctions four entities, including the Koryo Bank and Strategic Rocket Force of the Korean People's Army, and 14 people, including the head of Pyongyang's overseas spying operations.
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 measures adopted 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 UN ban on ballistic missile launches.
The UN Security Council first imposed sanctions on Pyongyang in 2006 over its ballistic missile and nuclear programmes and has ratcheted up the measures in response to five nuclear tests and two long-range missile launches.
North Korea is threatening a sixth nuclear test.
