The latest American move came a day after China and Russia vetoed a U.S.-led push to impose more United Nations sanctions on North Korea over its ballistic missile launches, publicly splitting the U.N. Security Council for the first time since it started punishing Pyongyang in 2006.
The vetoes came despite what the United States says was a sixth test of an intercontinental ballistic missile (ICBM) by North Korea this year and signs that Pyongyang is preparing to conduct its first nuclear test since 2017.
The U.S. Treasury Department in a statement said it targeted Air Koryo Trading Corp as well as Russian financial institutions the Far Eastern Bank and Bank Sputnik for contributing to procurement and revenue generation for North Korean organizations.
Washington also designated Jong Yong Nam, a Belarus-based representative of an organization subordinate to the North Korea Second Academy of Natural Sciences (SANS), who Washington said has supported North Korean organizations linked to the development of ballistic missiles.
North Korea's mission to the United Nations in New York did not immediately respond to a request for comment.
"The United States will continue to implement and enforce existing sanctions while urging the DPRK (North Korea) to return to a diplomatic path and abandon its pursuit of weapons of mass destruction and ballistic missiles," the Treasury's Under Secretary for Terrorism and Financial Intelligence, Brian Nelson, said in the statement.
China has been urging the United States to take action - including lifting some unilateral sanctions - to entice Pyongyang to resume talks stalled since 2019, after three failed summits between North Korean leader Kim Jong Un and then-U.S. President Donald Trump. The United States has said Pyongyang should not be rewarded.
Late on Friday, the top diplomats of South Korea, Japan and the United States issued a joint statement saying North Korea had "significantly increased the pace and scale of its ballistic missile launches since September 2021".
In the statement, U.S. Secretary of State Antony Blinken, South Korean Foreign Minister Park Jin and Japanese Foreign Minister Yoshimasa Hayashi urged Pyongyang to "return to negotiations."
