It is either. China just doesn't give a damn about policing such sanctions imposing by the US. Again, it is a US sanction not a UN sanction.
“Apparent violations by Chinese companies raise the question of whether China is intentionally trying to test the limits of America’s policy, or whether Beijing simply lacks the capacity to police Chinese firms across a range of industries,” said Stokes, a senior fellow focused on US-China relations at the Center for a New American Security.
Who fucking cares? US would sanction China if it could. It doesn't matter what China does or doesn't do.
They also zeroed in on China, with Senator Robert Menendez, a New Jersey Democrat, citing what he said was evidence that Chinese companies have been exporting dual-use technologies “that Russia needs to continue its onslaught of Ukraine.”
“It seems to me that we should not forsake the potential of sanctions against China if it is providing critical assistance, and it shouldn’t be able to hide behind some companies,” he told Undersecretary of State Victoria Nuland.

hina relationship with Russia is none of the US business. These lunatics think they can both sanction China, incite tensions in Taiwan Strait and ask China to not have good relationship with Russia. More importantly, relationship between the US and China is as bad as it can be. And China standing in the world is great except with the imperial West and its allies.
Nuland said that even before the invasion, the administration has had intense conversations with China “with regard to their relationship with Russia.” President Xi Jinping has avoided criticizing Russia over the war but has also offered to play a role in peace talks and come out against the use of nuclear weapons in the conflict.
“We’ve made clear that we will bring to their attention when we see sanctions violations by their companies,” Nuland said. “And we’ve been very clear with regard to the impact on our relationship and their standing in the world.”
