The incident and initial suspicions
The Yi Peng 3 departed from the Russian port of Ust-Luga on 15 November 2024. Shortly thereafter, on 17 and 18 November, two significant undersea cables were severed in the Baltic Sea. Analysis of maritime traffic data indicated that the vessel’s coordinates corresponded with the locations and times of the breaches, leading investigators to focus on the ship as a primary suspect.
German Defence Minister Boris Pistorius publicly suggested that the damage was likely the result of sabotage, intensifying concerns about the security of undersea infrastructure in the region. Western intelligence officials have expressed confidence that the Yi Peng 3 was involved in the cable cuts, though there is debate over whether the actions were accidental or deliberate.
Diplomatic negotiations and onboard investigation
Following the incident, the Yi Peng 3 anchored in the Kattegat Strait between Denmark and Sweden, remaining stationary for approximately a month. During this period, diplomatic discussions ensued between Stockholm and Beijing, aiming to facilitate an investigation.
On 19 December 2024, Swedish police, acting as observers, boarded the vessel at the invitation of Chinese authorities. This collaborative effort included representatives from Germany, Sweden, Finland, Denmark, and China. The Swedish police clarified that their participation was observational, with the primary investigation led by Chinese officials.
Swedish Prime Minister Ulf Kristersson had previously urged the ship to return to Sweden to aid the investigation, underscoring the incident’s significance to Swedish national security.
Implications and ongoing concerns
The damage to the undersea cables has raised alarms about the vulnerability of critical infrastructure in the Baltic Sea. While the cables have been repaired, the incident has prompted calls for increased security measures and international cooperation to safeguard such assets.
The involvement of a Chinese-flagged vessel has added a layer of complexity to the situation, intersecting with broader geopolitical tensions. The swift resumption of the Yi Peng 3‘s voyage, now en route to Port Said, Egypt, following the onboard investigation, leaves several questions unanswered.
As the investigation continues, the international community remains watchful. The incident serves as a stark reminder of the delicate balance between maritime operations and the security of global communication networks. The outcomes of this inquiry may influence future policies and collaborative efforts to protect undersea infrastructure from both accidental damage and potential acts of sabotage.
