Japan will "stand firmly" by the United States in its campaign against international terrorism, Prime Minister Junichiro Koizumi told U.S. President George W. Bush in a meeting Tuesday.

Koizumi said Japan will cooperate as much as possible without using military force; Bush replied that declining to use military power does not reduce the importance of the bilateral alliance.

"We Japanese firmly stand by the United States to fight terrorism," Koizumi told reporters in English after emerging with Bush from an hourlong meeting in the Oval Office.

The Koizumi-Bush summit was part of U.S. efforts to forge a global coalition against international terrorism. The talks also covered the political and economic impacts of the attacks.
