AMSTERDAM (AP) — Japan’s Prime Minister Shinzo Abe has paid a visit to the Anne Frank House museum in Amsterdam, a diplomatic move ahead of a meeting with the leaders of the U.S. and South Korea to discuss North Korea.

Abe also expressed regrets Sunday that 300 copies of Anne Frank’s diary were vandalized recently in Tokyo libraries. A suspect has been arrested and confessed.

In the run-up to the Nuclear Security Summit in The Hague, Abe has sought to undo fallout from his December visit to Yasukuni Shrine, which honors all Japanese military casualties — including war criminals. The move angered China and South Korea and revived concerns about Abe’s nationalist and revisionist tendencies.

Earlier this month Abe said he won’t undo Japan’s past apologies for its actions in World War II.
