Yi Peng 3 crossed both cables C-Lion 1 and BSC at times matching when they broke

October 2023 there was similar incident where Chinese cargo ship cut Balticonnector cable and EE-S1 cable. Chip named 'Newnew Polar Bear' under Chinese flag and Chinese company Hainan Xin Xin Yang Shipping Co, Ltd. (aka Torgmoll) with CEO named Yelena V. Maksimova, drags anchor in the seabed cutting cables. Chinese investigation claims storm was the reason, but there was no storm, just normal windy autumn weather. The ship just lowered one anchor and dragged it with engines running long time across the seabed until the anchor broke.

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.

What are some concrete reasons why someone would want to damage these cables? Who benefits?

Prof. Stephen Kotkin — an historian who wrote multiple extensive biographies on Stalin — calls the Russian regime a "gangster regime".*

Once you see them as gangsters, it's not difficult to see why they would do this.

*A full link with exact timestamp of Kotkin saying this is [1]. Here he talks about why Merkel kept making oil deals with Putin even though in hindsight this was probably not the best idea. Kotkin argues that, yes, according to econ 101 trade is good for both parties, but not when the opposite party is a gangster. Merkel thought that Putin was thinking like her, but he wasn't.
