Japan and the United States have signed a revised bilateral agreement to boost logistics cooperation between their military forces in light of the deepening defense alliance under the new security legislation that came into force in March.

The formal signing took place Monday in Tokyo.

The Self-Defense Forces have been able to provide to the U.S. military supplies such as food and oil as well as transportation and other services as logistic support activities under the bilateral Acquisition and Cross-Servicing Agreement. But the provision of ammunition had been limited to military emergencies affecting Japan.
