Prime Minister Yukio Hatoyama and U.S. President Barack Obama vowed Friday to bolster the bilateral alliance and cooperate on pressing global issues, including climate change and nuclear disarmament.

The two also touched on the sensitive relocation of U.S. Marine Corps Air Station Futenma in Okinawa. The issue has cast a shadow on bilateral relations. They said it was their common goal to resolve the issue as soon as possible.

Earlier this week, the two governments decided to form a ministerial-level working group to find a way to resolve the issue, just in time to avoid direct conflict at the summit.
