In the past, the island would issue an air raid alert if People’s Liberation Army (PLA) aircraft or vessels came within 70 nautical miles (80 miles) of the Taiwanese coast, but that threshold has been quietly revised to 24 nautical miles in recent years.
The change came to light on Sunday when RW News reported that the shift could leave people with just three minutes to seek shelter in an air raid.
Asked about the decision, Taiwanese Defence Minister Wellington Koo Li-hsiung said the change reflected the growing threats posed by PLA activities.
“The military will respond by closely monitoring and analysing the situation to discern PLA intentions, ensuring they cannot operate unchallenged within Taiwan’s vicinity.”
