TOKYO — A conflict in the Taiwan Strait would present one of the biggest challenges to Japan’s security, a new defense white paper shows, as Tokyo delves into unprecedented detail on how it plans to protect the country’s territory in such a scenario.
Japan must “pay close attention” to the Taiwan Strait “with a sense of crisis more than ever before,” the document published Tuesday said.
The Defense Ministry cited the importance of cross-strait stability in its annual report for the first time, signaling a growing sense of urgency from the 2020 white paper, which said “attention needs to be paid to trends”.
