Yeah, but it's a bit far away for China. They prefer harassing their closer neighbors.

In 2023, Balticconnector gas pipeline between Estonia and Finland was broken by a Chinese ship Newnew Polar Bear dragging its anchor in the sea floor.

In 2024, another Chinese ship damaged telecom cables in the Baltic Sea area between Sweden and the Baltic countries.

They even had data showing them meandering over the cable, pulling the anchor under power.

They prefer to bankroll Russia.
