These things happen sometimes, ship anchors sometimes damage cables, but not this often and without serious problems in the ship. Russians are attempting plausible deniability.

As for the core of your question: there is no benefit, it's just his mentality. "The West" supports Ukraine so let's just do some harm, retaliate in some way. Burn some buildings here and there, plants some inflammable materials on airplanes etc. Pointless for you and me, meaningful for that guy.
What we don't know is if China knew they were going to try this beforehand or not. Flag of Convenience is common enough that we can't be sure. This could have been planned on the high level from China and we would never know - something conspiracy theorists will run with! If China knew they would probably give the crew a sever punishment, but unofficially it is for getting caught and not doing the act. Most likely though China didn't know before hand.
