Do you have a source more recent than https://archive.is/3weox (WSJ article)?

It appears to be a Chinese ship, although it is not clear that the Chinese government sanctioned whatever happened.

If you read the article it even states that it's a Chinese ship but with a Russian crew that departed from Russia. They leased it from China. If you have an accident with a leased Chinese car, no one would say "the Chinese did it".

damn Russians framing Chinese is a good proof their partnership isn't going well (same with Americans exploding germany infrastructure [nordstream])

The difference is that your point is just conjecture. Afaik nobody knows exactly who was responsible for the pipe. But we do not whose ship it was and who was on the crew at the time.

True. But the way you phrased it, it sounds like now the Russians had "an accident" in a Chinese ship and unfortunately some cables got cut as a result. Oh those poor clumsy Russian, surely they never meant any harm. /s

Anyways, I think the original "pretty dark view" can easily be extended to cover both these nations and it wouldn't be far from the truth (which, as you may correctly add, is the US-centric kind of truth - the best kind of truth as far as personal freedoms are concerned).

No, it does not. It says "The crew of Yi Peng 3, which is captained by a Chinese national and includes a Russian sailor..." That is not at all "a Russian crew."
