Four Chinese coast guard vessels pushed into waters around Taiwan's Kinmen islands, another squeeze on Taipei that keeps this frontline flashpoint tense.

• Four Chinese coast guard ships gathered south of Kinmen in the morning and crossed into Taiwan's restricted waters.
• Taiwan's coast guard sent patrol boats alongside them and ordered them out in Chinese and English until all four left before noon.
• Taipei says Beijing is using fake law enforcement to claim real control over the sea around Kinmen.
• Chinese broadcasts to Taiwanese crews pushing unification are being treated as psychological pressure, not policing.
• Taiwan's stance is to neither provoke nor back down, with more patrols and surveillance in the area.

Outlook: These incursions have become routine and are likely to keep repeating, with each one testing how far Taiwan will hold the line.
