The US report purportedly showed that North Korea exceeded the authorized import quotas for refined oil.
“The Russian Federation and China requested more conclusive evidence to make a judgment,” said the report, seen by AFP.
The document also noted that “the DPRK continued to flout UN Security Council resolutions through illicit maritime exports of commodities, notably coal and sand.”
Pyongyang also “continued to import luxury goods and other sanctioned items, including luxury vehicles, alcohol and robotic machinery.”
The country has continued “to access international banking channels in violation of UN sanctions, mainly by using third-party intermediaries,” the report found.
North Korea “continued illegally to acquire virtual currencies and to conduct cyber-attacks against global banks to evade financial sanctions.”
China, which is often suspected of helping North Korea despite the sanctions, said Monday in a statement from its UN mission that it had “always faithfully and seriously fulfilled its international obligations”.
This was despite the “huge losses” suffered by Beijing from implementing UN decisions, it said.
“It is imperative for the Security Council… to make necessary adjustments to the sanctions measures especially in areas concerning the livelihood” of North Korean citizens, it said in the statement.
China proposed a resolution in late 2019, along with Russia, that would allow for the lifting of certain bans, particularly on fishing and textiles.
