My comment:
(a) I wonder why China suddenly talks about sovereignty of Okinawa. Does China want to deny Japan's sovereignty? This is not addressed in VOA report.
(b) Assuming (1) is true, that Generalissimo Chiang Kai-shek could have said yes to FDR, could China have taken Okinawa back?
(c) "东京福祉大学国际交流中心主任远藤誉."
