Taiwan’s top economic representative in Japan, Lee Yi-yang, boycotts this year’s memorial for the 81st anniversary of the U.S. atomic bombing of Nagasaki. Lee says he and two deputies do not attend because the seats assigned to Taiwan’s representatives are not among those reserved for diplomatic missions.

Lee, head of the Taipei Economic and Cultural Representative Office in Tokyo, posts that the seating arrangement denies Taiwan’s status and sovereignty. His office links the decision to concerns that Nagasaki is acting in line with pro-China positions, and says a lower-ranked official is sent instead from Fukuoka.

Nagasaki officials respond that the seating for Taiwanese representatives is placed behind other envoys and is not clearly labeled as non-diplomatic or separate from diplomatic seating. The dispute centers on how Taiwanese representatives are categorized for the ceremony and how seat placement is interpreted by both sides.
