The White House says President Barack Obama and Japanese Prime Minister Yukio Hatoyama have expressed satisfaction with plans to move a U.S. Marine base to a less crowded part of the Japanese island of Okinawa. Obama and Hatoyama spoke in a telephone conversation on Thursday as the president was flying to Chicago. Details of their conversation came as Washington and Tokyo issued a joint statement outlining a new agreement on keeping the base on the island of Okinawa. Hatoyama's decision disappointed many of the island's residents, who complain about base-related noise, pollution and crime. The White House also says Obama and Hatoyama pledged to work closely with South Korea after a North Korean torpedo reportedly sank its neighbor's ship.
