Swedish police have boarded a Chinese ship, the Yi Peng 3, as part of an investigation into recent breaches of undersea internet cables in the Baltic Sea. Following weeks of secret negotiations, China has permitted officials from Sweden, Finland, Germany, and Denmark to conduct their inquiry aboard the vessel. The incident has raised global concerns over the security of critical undersea infrastructure, as reports suggest potential involvement by Russian intelligence in orchestrating these sabotage efforts. The investigation continues amid rising international tensions and scrutiny over the vulnerabilities of submarine cables.
