The Chinese survey vessel Yuan Wang 5 docked on Tuesday at Sri Lanka's Chinese-built port of Hambantota, a port official said, a move likely to stoke concern in neighbouring India about the growing influence of its bigger and more powerful rival.
The movements of the ship have fuelled contention between India and China, two of Sri Lanka's biggest allies in its current economic crisis, as India fears China could use the port, near the main Asia-Europe shipping route, as a military base.
"The vessel will be berthed for three days," the official, who declined to be identified as he was not authorised to speak to the media, told Reuters from the southern port.
