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.

Given that ships often cut undersea internet cables and China has the biggest export economy, doesn't it make sense that the most likely country to accidentally cut an internet cable would be a Chinese trade ship?

On average, it seems like undersea internet cables break 200+ times per year. For example, Vietnam's internet cables break on average 10 times per year.

What would be the motivation for a Chinese trade ship to deliberately cut an internet cable? It has next to no impact on internet communication and only serves to annoy a small amount of people for a short period of time. In addition, China and Europe are trying to have a better relationship in general so it doesn't make sense for the Chinese government to order this.
