In a developing situation in the Baltic Sea, two undersea cables were damaged last week, one connecting Sweden and Lithuania, and another between Finland and Germany.
The Chinese vessel Yi Peng 3 has come under scrutiny as it was reportedly near the sites of the cable disruptions.
Swedish Prime Minister Ulf Kristersson has expressed a desire for the ship to move into Swedish waters to facilitate cooperation in the investigation, though he emphasized that this request does not imply any accusations.
Diplomatic discussions are ongoing with China to allow boarding of the vessel for further investigation.
Meanwhile, the Danish navy continues to monitor the ship, which remains stationary in the Danish economic zone.
Swedish authorities have launched a preliminary investigation into potential sabotage, with international cooperation being sought to resolve the issue.
