China is willing to maintain communication and cooperation with the concerned countries to promote the further handling of the incident, says Mao Ning, spokesperson for the Chinese Foreign Ministry.
The ship is suspected of being involved in the destruction of two data cables in the Baltic Sea, which is being investigated as sabotage.
According to The Wall Street Journal, investigators suspect that Yi Peng 3 intentionally dragged its anchor 16 miles along the Baltic Sea floor, thereby destroying the cables, one between Finland and Germany, and the other between Sweden and Lithuania.
Swedish police and accident investigators were on board as observers last week when the ship was inspected in the Kattegat.
Jonas Bäckstrand, Deputy Director-General of the Accident Investigation Board, has previously said that the visit has provided a clearer picture of what may have happened.
We have received more information about the ship, the ship's equipment, and the crew has spoken to us, he said the day after the observation.
However, Chinese authorities denied prosecutor Henrik Söderman, who is leading the criminal investigation into the communication cables, access to board Yi Peng 3.
The decision has prompted Foreign Minister Maria Malmer Stenergard (The Moderate Party) to react:
"It is remarkable if the ship leaves without the prosecutor, within the framework of a Swedish preliminary investigation into a crime, being given the opportunity to inspect the ship and hear the crew," she wrote in a comment the same day the ship left the Kattegat.
