Sweden has sharply criticised China for refusing to allow the Nordic country’s main investigator on board a Chinese vessel suspected of severing two cables in the Baltic Sea.

The Yi Peng 3 sailed away from its mooring in international waters between Denmark and Sweden on Saturday, and appears to be heading for Egypt after Chinese investigators boarded the ship on Thursday.

The Chinese team had allowed representatives from Sweden, Germany, Finland and Denmark on board as observers, but did not permit access for Henrik Söderman, the Swedish public prosecutor, according to authorities in Stockholm.

“It is something the government inherently takes seriously. It is remarkable that the ship leaves without the prosecutor being given the opportunity to inspect the vessel and question the crew within the framework of a Swedish criminal investigation,” foreign minister Maria Malmer Stenergard said in comments provided to the Financial Times.

The Swedish government had put pressure on Chinese authorities for the bulk carrier to move from international waters into Swedish territory to allow a full investigation over the severing of Swedish-Lithuanian and Finnish-German data cables last month.

People close to the probe said the boarding of the vessel on Thursday had shown there was little doubt it was involved in the incident.

Yi Peng 3 belongs to Ningbo Yipeng Shipping, a company that owns only one other vessel and is based near the eastern Chinese port city of Ningbo. A representative of Ningbo Yipeng told the FT in November that “the government has asked the company to co-operate with the investigation”, but did not answer further questions.

There is a split among countries over the motivation behind the cutting of the cables. Some people close to the investigation said they believed it was bad seamanship that may have led to the Yi Peng 3’s anchor dragging along the seabed in the Baltic Sea.

However, other governments have said privately that they suspect Russia was behind the damage and may have paid money to the ship’s crew.

The severing of the two cables was the second time in 13 months that a Chinese ship has damaged infrastructure in the Baltic Sea.

The Newnew Polar Bear, a Chinese container ship, damaged a gas pipeline in October 2023 by dragging its anchor along the bottom of the Baltic Sea for a considerable distance during a storm. Officials reacted slowly to that incident, allowing the vessel to leave the region without stopping, something that they were keen to prevent in the case of the Yi Peng 3.

Nordic and Baltic officials are sceptical about the possibility of the same thing occurring twice in quick succession. “The Chinese must be truly dreadful captains if this keeps on happening innocently,” said one Baltic minister.
