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 thedrive.com/…/video-of-anti-ship-missile-strikin…
I may have remembered wrong, I thought I saw an initial denial before the video was posted but can’t find it either at this point. I guess we’ll see if there’s a confirmation for this one in the next few days.
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.
