TOKYO (Reuters) – Japan is studying plans to cope with an influx of perhaps tens of thousands of North Korean evacuees if a military or other crisis breaks out on the peninsula, including ways to weed out spies and terrorists, a domestic newspaper said.
The Japan Coast Guard would escort boats fleeing North Korea to designated ports, where police would screen them by checking their identity and possible criminal records and expel those deemed a threat, the Yomiuri newspaper said on Thursday.
It did not say where those people would be sent, however. Evacuees granted temporary entrance would be transferred to emergency detention centers, probably in southern Japan, after completing quarantine and other procedures.
