The latest American move came a day after China and Russia vetoed a US-led push to impose more United Nations sanctions on North Korea over its ballistic missile launches, publicly splitting the UN Security Council for the first time since it started punishing Pyongyang in 2006.

The vetoes came despite what the US 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 US 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 organisations.

Washington also designated Jong Yong-nam, a Belarus-based representative of an organisation subordinate to the North Korea Second Academy of Natural Sciences (SANS), who Washington said has supported North Korean organisations 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 US 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 US 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-US president Donald Trump.

The US has said Pyongyang should not be rewarded.
