The U.S. Space Force is considering setting up a unit in Japan, its top uniformed officer said Monday in Tokyo, underscoring the importance of bilateral collaboration in the space domain, where China is ramping up its capabilities.

"We're just in the planning phases to figure out exactly what that headquarters would do," Gen. Chance Saltzman, who is leading the newest branch of the U.S. military, told reporters in Tokyo.

The move comes as the U.S. Space Force, created in December 2019, is expanding its presence in the Asian region. In November, it established a unit within the U.S. Indo-Pacific Command based in Hawaii, followed by the creation of a subordinate unit in South Korea in December.
