Cuba Denies Chinese Intelligence Facilities Despite CSIS Satellite Evidence of Operational Bejucal Antenna Array

BLUFHavana's denial sidesteps the specific SIGINT sites confirmed by satellite imagery, making an on-the-record acknowledgment from Cuba or China very unlikely before December 1.

Cuban Deputy Foreign Minister Carlos Fernández de Cossío rejected claims of Chinese intelligence facilities in Cuba, posting on X on August 26 that a Hill column by analyst Gordon Chang was filled with "ridiculous fabrications" about foreign military bases 12. Cossío's denial addressed conventional military bases rather than signals intelligence sites, the specific facilities Chang's article and the underlying reporting describe 13. That reporting cites a July State Department report stating China operates three of 18 known signals intelligence facilities in Cuba, and CSIS satellite imagery from June confirming construction of a 32-antenna circularly disposed antenna array at the Bejucal site was complete and the system likely operational, larger and more capable than any Cuban antenna array CSIS has previously observed there 13. The exchange follows an August 6 Rubio announcement of sanctions on Cuban military representative Waldo Pérez Cortés and seven others for facilitating Chinese military equipment acquisitions, and a Chinese Foreign Ministry statement from spokesperson Guo Jiakun calling China-Cuba cooperation "legitimate and transparent" 12.

Analysis
Cossío's blanket denial forecloses any near-term diplomatic opening for Washington to extract an admission, leaving US officials to build their case on satellite imagery and technical reporting rather than acknowledgment from Havana or Beijing. Cuba or China is very unlikely to issue an on-the-record acknowledgment of Chinese signals-intelligence facilities before December 1. Confidence in this judgment is low, resting on a single official statement that addresses conventional bases rather than the signals-intelligence sites named in the underlying reporting. Continued sanctions pressure and congressional attention will more likely sharpen the standoff than shift Havana's public position, and each new denial narrows the space for a face-saving clarification later.
