Taipei has demanded that Beijing release a Taiwanese-registered fishing boat boarded and seized by the China Coast Guard near the Taiwanese-controlled island of Kinmen late Tuesday.

The incident is the latest source of tension between communist-ruled Beijing and democratic Taipei, following ramped-up patrols and training by China around Kinmen — just 3 kilometers from the mainland.

Taiwan’s coast guard said in a statement that it had received a report from the fishing vessel that it had been stopped by the China Coast Guard in waters around 23.7 nautical miles (44 km) from Kinmen's Liaoluo port.
