Prime Minister Junichiro Koizumi's decision Monday to call a general election may end up stalling Japan's diplomatic agenda, including talks on realigning the U.S. forces in Japan.

Whether Koizumi visits Tokyo's war-related Yasukuni Shrine on Aug. 15 is also attracting attention in the diplomatic arena, since he is more likely to take the plunge now that his grip on power is at stake, pundits say. A visit on the 60th anniversary of Japan's World War II surrender would further damage ties with China and South Korea.

Diplomats also worry the election may create a political and administrative vacuum at a time when crucial decisions are needed.
