Going forward, the world's second-largest economy is expected to "vociferously protest" Tuesday's action, but it won't ultimately cut off cooperation with the USA on North Korea or directly retaliate against American firms, according to the Eurasia note. "Our position is clear and consistent", Chinese Foreign Ministry spokeswoman Hua Chunying told reporters at a regular press briefing.
The White House isn't afraid of angering potential partners in its quest to pressure North Korean leader Kim Jong Un into denuclearization, experts said.
Beijing has already slammed Washington over the new sanctions, which it called "long-arm jurisdiction over Chinese entities and individuals". The DPRK responded by saying it planned to fire four missiles into the waters off Guam.
But Pyongyang Wednesday disclosed significant technological advances in its missile programmes and ambitious plans to further improve its capabilities. They target companies that have dealt in natural resources such as coal and minerals or engaged in financial transactions for North Korean interests.
"From my experience, the Chinese are more interested in negotiating a freeze of North Korea's program versus getting to an actual solution", Ruggiero added.
"It is unacceptable for individuals and companies in China, Russia and elsewhere to enable North Korea to generate income used to develop weapons of mass destruction and destabilise the region", Treasury Secretary Steven Mnuchin said in a statement.
The U.S. Treasury Department slapped sanctions on ten entities based in China, Russia, Singapore and Namibia.
The data also provided details on the effect of the sanctions to North Korean coal imports; in the first quarter, Pyongyang shipped 2.7 million tons of coal valued at $220.6 million to China, accounting for 43 % of its total imports then.
The report noted that "Donggang, which is administered by Dandong, northeastern China's Liaoning Province, serves as a national hub for the seafood trade between China and North Korea".
The US Treasury has slapped Russian Federation with a fresh round of sanctions over alleged dealings with North Korea.
Another company, Mingzheng International Trading Limited, which maintains offices in Hong Kong and mainland China, was in fact a front for the Foreign Trade Bank, North Korea's main foreign exchange bank, the Treasury Department said.
An English-language Chinese newspaper says seafood business in the Chinese city of Donggang, which borders North Korea, has been hit hard after Beijing placed a ban on North Korean seafood imports beginning last Tuesday.
