A Chinese vessel, Yi Peng 3, is currently under scrutiny as it remains stationary in the Kattegat, monitored by the Danish navy.
The ship is suspected of being involved in the recent damage to undersea data cables in the Baltic Sea.
While the Danish military has halted the vessel, Swedish authorities express interest in questioning the crew, though they have not yet boarded the ship.
The Swedish navy's HMS Belos is investigating the damaged cables, which lie at depths of 30-45 meters.
Despite the suspicions, China's foreign ministry denies any wrongdoing, asserting that their ships adhere strictly to maritime laws.
The incident has heightened tensions, with experts noting that strong evidence is required to justify boarding the vessel, given its location in international waters.
