  In January 2021, when Biden took office, there was some conspiracy theory going around Chinese social media after a state news article was quoted as saying that the US naval officials (specifically the Navy) were meeting with PLA officials to discuss the return of POWs and KIAs in the present tense. And people were speculating, hang on.. the PLAN captured some US servicemembers?
  And the US sub that crashed into the underwater mountain? Another theory is that the sub was being chased by Chinese ASW units. Their argument is that the area is well documented, so the sub charts should have all the relevant data to safely navigate the area. Unless it was being harassed and taking evasive maneuvers. Another part to the theory that the PLAN was involved was because senior US Navy officials were supposedly pissed off at China for this incident.
  An interesting question, if a US sub was detected within undisputed Chinese waters, would the PLA be legally permitted to fire upon it? Or have an unscheduled anti-submarine drill.
context: Good luck finding an American sub let alone capture it.  They're not like China or Russia's loud counterparts.
