The new buildings went up near the site of two US-built facilities that were suddenly demolished last year.
The work has fed rumors of a looming Chinese military presence in an important part of Southeast Asia. Two new buildings appear to have been built in a matter of weeks at Cambodia's Ream Naval Base, where that construction and demolition of US-funded buildings have raised concerns about a looming Chinese presence.
Satellite photos taken by Maxar and published by the Asia Maritime Transparency Initiative show land clearing beginning sometime after April 17, construction starting in early May, and the buildings finished by May 21. The two buildings, both about 115 feet long and 20 feet wide, are located just north of the site of facilities built with US support that Cambodia's government demolished late last year. Imagery previously published by AMTI, part of the Center for Strategic and International Studies, showed that one US-built building, the Tactical Headquarters of the National Committee for Maritime Security, was torn down in September.
