Significance

The allies established a Standing Senior Liaison Group in 1979 to oversee seventeen joint projects. In the 1990s, this collaboration expanded to include commercial issues with a 1990 agreement on satellite procurement, followed by a 1994 agreement for joint development on a remote sensing system for environmental surveys, among other cooperation. The first Comprehensive Dialogue in 2013 signaled a shift toward more space security cooperation, with U.S. and Japanese officials signing a memorandum of understanding to share information on space situational awareness and affirming collaboration in use of space for Maritime Domain Awareness. The governments have since taken steps to clear the technical hurdles necessary to implement the agreement.
