Taiwan has responded after China appeared to take part in military drills that simulated an attack following a major US official visiting the island.
China has now ended a number of live-fire military drills across seven zones around Taiwan in response to a visit by US House Speaker Nancy Pelosi to the island one that infuriated Chinese officials.
However, there was an escalation on Sunday, with Taiwanese warships retaliating to the drills, sailing in close quarters to Chinese ships in the Taiwan Strait.
A source told the Reuters news agency that some Chinese ships crossed the median line an unofficial buffer which separates the two sides.
They added the Taiwanese side monitored Chinese ships as they “pressed” the line, in an effort to deny them the chance to cross.
