In an investigative piece for The Wall Street Journal, journalist Bojan Pancevski reports on an unfolding international probe involving the Chinese bulk carrier Yi Peng 3, which is suspected of severing critical undersea data cables in the Baltic Sea. The incident has raised concerns over maritime security and potential geopolitical motivations, with NATO warships now surrounding the vessel in international waters.

Incident Details

The Yi Peng 3, a 225-meter-long ship carrying Russian fertilizer, reportedly dragged its anchor for over 100 miles in Swedish waters on 17–18 November, damaging two crucial undersea cables. The cables connected Sweden and Lithuania, and later Germany and Finland, leading to significant disruptions. Investigators suspect that the captain, a Chinese national, and the crew, which includes a Russian sailor, may have been acting under the influence of Russian intelligence.

According to Pancevski, the ship’s transponder—used to monitor its position—was switched off during parts of its journey, a tactic often referred to as a “dark incident” in maritime operations. Analysts from Kpler, a global shipping data firm, found damage to the vessel’s anchor and hull consistent with deliberate dragging, further diminishing the likelihood of an accident.

International Reactions

Swedish authorities, who opened a sabotage investigation, were joined by German and Danish counterparts in probing the incident. NATO vessels from Denmark, Germany, and Sweden have surrounded the Yi Peng 3, but under international maritime law, they cannot compel the ship to dock for a more thorough investigation. Negotiations with its Chinese owner, Ningbo Yipeng Shipping, are ongoing to secure access to the vessel and question the crew.

A spokesperson for Arelion, the operator of the Sweden-Lithuania cable, confirmed that repairs were completed on 28 November. However, the damage has reignited discussions about the vulnerability of undersea infrastructure, especially in light of recent geopolitical tensions.

Russian and Chinese Responses

Russian officials have dismissed the accusations as “absurd and unsubstantiated,” claiming that similar scrutiny was absent when Ukraine was accused of sabotaging the Nord Stream gas pipelines in 2022. Meanwhile, China’s Foreign Ministry reiterated its commitment to safeguarding international submarine cables, emphasizing cooperation under international law.

Experts like Benjamin L. Schmitt, a senior fellow at the University of Pennsylvania’s Kleinman Center for Energy Policy, highlighted the suspicious shift in the Yi Peng 3’s operational patterns. Having operated exclusively in Chinese waters until March 2024, the ship began frequenting Russian ports, raising questions about its activities.

Escalating Maritime Security Concerns

This incident follows a series of suspected sabotage efforts targeting Europe’s critical infrastructure, which many intelligence officials attribute to Russia. The Baltic region, already tense due to Sweden’s recent NATO membership and the ongoing war in Ukraine, has become a focal point for security threats.
