It continues to support our forward presence in the region, both for its own security and the security of its neighbors. The most tangible measure of this support is Japan's commitment to provide over 70 percent of the cost of keeping our troops on its soil. This helps our readiness, because basing troops overseas is very expensive, far more expensive than basing them at home. And it serves the U.S. national interests, by keeping the region stable and secure so that U.S. goods and ideas can flow freely. But our presence is only one factor in keeping regional stability.
Japan also plays a key role in the security of the region.
The framework agreement that halted North Korea's nuclear program could not have been reached without Japan's willingness to help provide North Korea with safe nuclear reactors. Japan has also been an active player in regional security dialogues, helping build foundations for confidence and cooperation in an area marked by a history of conflict. As Japan continues to contribute to regional security, it is also increasing its role in global security initiatives. Just a few years ago, Japanese law did not permit participation in peacekeeping operations. Today, Japan has a very successful record of operations in Cambodia, Mozambique and Zaire.
