The designations are the latest effort by the Donald Trump administration to ramp up pressure on Pyongyang to fully and completely denuclearize.
Meanwhile, South Korea's foreign ministry said that the latest United States sanctions appear to reflect Washington's belief that both sanctions and dialogue are important in achieving the complete denuclearization of the Korean Peninsula.
United Nations diplomats familiar with discussions said Russian Federation was angered that the panel used a lot of USA intelligence in the initial report that Moscow claimed was incorrect.
Sources at that time also said Russia blocked a USA request that two Russian shipping companies and six of their vessels be sanctioned over oil shipments to the North.
The US in July had demanded without success an end to all oil exports to North Korea, citing satellite photographs and expert reports to claim illegal ship-to-ship transfers had allowed Pyongyang to evade sanctions over its nuclear weapons and ballistic missile programs.
"Treasury is once again warning the IT industry, businesses, and individuals across the globe to take precautions to ensure that they are not unwittingly employing North Korean workers for technology projects", he said, noting that the U.S. will continue to enforce sanctions until the "final, fully verified denuclearization" of North Korea.

"This is a risky precedent and a stain on the important work of the panel", Haley said.
Haley said Russian interference "sets an unacceptable precedent that damages the sanctity of the United Nations independent panel reporting process".
The United States is imposing sanctions on two North Korean-controlled information technology companies based in China and Russian Federation.
Treasury Secretary Steve Mnuchin said the sanctions were meant to stop the flow of illicit revenue to North Korea from overseas IT workers hiding behind front companies and aliases.
