I am sure the USFK PAO did not have this on their bingo card of things they would have to respond to this week:

The United States Forces Korea on Monday denied online media reports of 99 Chinese spies being captured by the US and South Korean military and confessing to election rigging, saying the notion is “entirely false.”
“The depiction of US forces and the allegations in the mentioned ROK media articles are entirely false. US Forces Korea remains committed to its mission of maintaining stability and security on the Korean Peninsula in accordance with the US-ROK Mutual Defense Treaty. We urge responsible reporting and fact-checking to prevent the spread of misinformation that could harm public trust,” the USFK said in a public statement, referring to South Korea’s formal name, the Republic of Korea.
Thursday’s claim by Sky Daily, a far-right platform founded in 2011, alleged that the South Korean military cooperated with the US military to take into custody 99 Chinese nationals at the National Election Commission building during the Dec. 3-4 imposition of martial law.

You can read more at the link, but even if the Chinese had spies in the NEC this would have nothing to do with USFK. This would be completely a ROK counterintelligence and law enforcement matter to arrest Chinese spies.
