Overview

• Two key House committees have formally requested a classified briefing and threat assessment from DHS on four suspected Chinese surveillance sites in Cuba.
• The suspected signals intelligence facilities, identified by satellite imagery and CSIS analysis, are reportedly capable of monitoring U.S. military, commercial, and space communications.
• Three sites are near Havana—Bejucal, Wajay, and Calabazar—while a fourth is in Santiago de Cuba, with evidence of recent upgrades like advanced antenna arrays.
• China has invested nearly $8 billion in Cuban infrastructure since 2000, including Huawei and ZTE-built telecom networks, raising concerns about espionage capabilities.
• Lawmakers warn that these facilities could serve as a forward base for Chinese electronic warfare and intelligence, directly undermining U.S. security interests.
