How so? It’s not like the most likely method to sabotage the pipeline would have to be explosives.
I dont see why a Hong Kong ship would want to blow up a pipeline.
Again, you not being able to come up with a reason doesn’t mean that it was accidental.
And I’m not saying it’s definitely deliberate or accidental, I’m just saying that making assumptions based on whether you can come up with a reason for it being sabotage is, in a word, silly. Well, at least unless you have some sort of deeper understanding of Chinese politics that most of us don’t have.
Plus this is all speculation at this point anyhow, since that ship’s connection to the pipeline damage hasn’t been verified in any way.
