Yemen's Houthi group on Monday said it has carried out a strike on the American military cargo ship OCEAN JAZZ in the Gulf of Aden, claiming to have used sea-based missiles.

I would certainly trust Chinese official news agency, which is a neutral party, over whatever US, that's an active participant in the conflict, is claiming. And in fact, US denied another attack just a few days ago that we now have video evidence for, so US has already been caught lying once here https://www.thedrive.com/the-war-zone/video-of-anti-ship-missile-striking-ship-during-red-sea-attack-surfaces

State media has no real reason to lie when it relates to matters not relating to the state. They could just as easily omit the coverage, so I'm more liable to believe Xinhua than The Guardian (British) or Reuters (also British), both who participated in the strikes on Yemen.
