China’s Djibouti Spy Hub: New Radar Tracks US Ships in Red Sea Chokepoint
Beijing expands its only overseas military base with advanced radar and communications to watch US and Iranian.
China has significantly expanded its military capabilities in Djibouti, transforming its overseas base into a sophisticated surveillance outpost near the strategically vital Bab el-Mandeb Strait. Recent satellite imagery analyzed by the Center for Strategic and International Studies (CSIS) reveals major upgrades, including new communication compounds built since mid-2024.
The enhancements feature advanced antennas, radar systems, and satellite communications equipment designed to monitor activities across the Red Sea and Gulf of Aden. According to CSIS, the varied orientation and type of equipment allow China to detect signals across multiple frequencies, providing a more comprehensive view of regional military and maritime movements.
Strategic significance of the upgrades: China
The Djibouti base, operational since 2017, is China’s only officially acknowledged overseas military installation. Its location near the Bab el-Mandeb Strait—a critical chokepoint for global shipping—positions Beijing to closely observe developments in the region. The strait, which separates Djibouti from Yemen, is one of the world’s most important maritime passages, handling a significant portion of international trade.
The upgrades come amid heightened tensions in the area. The ongoing U.S.-Iran conflict, the potential closure of the Strait of Hormuz, and the Houthis’ control of Yemen’s Red Sea coast, including Perim Island, have increased the need for intelligence-gathering. China’s expanded capabilities allow it to track military movements involving the U.S., Iran, and the Houthis, as well as monitor shipping lanes that are vital to global commerce.
Regional military presence and future implications
China is not the only foreign power with a military presence in Djibouti. The U.S., France, Italy, and Japan also operate bases within 16 kilometers of China’s facility. The proximity of these installations underscores the strategic importance of the region, particularly as conflicts involving the Houthis, Iran, Israel, and the U.S. continue to escalate.
The new communication compounds suggest Beijing is planning a long-term presence, aiming to strengthen coordination between its forces in Africa and the Gulf. While CSIS notes that the imagery alone cannot confirm whether the base is actively intercepting communications, the upgrades provide China with a more robust understanding of the operational environment.
As regional tensions persist, other nations may respond by enhancing their own surveillance capabilities near the Bab el-Mandeb Strait. The U.S., in particular, could increase its monitoring efforts to counterbalance China’s growing influence. The upgrades at China’s Djibouti base signal Beijing’s intent to play a more assertive role in global security, with potential implications for both cooperation and competition among major powers.
