China quietly upgraded a military base in Djibouti with new surveillance gear just 6 miles from a U.S. counterterrorism hub — and a former Pentagon official says the buildup amounts to an eavesdropping post over one of the world's busiest shipping chokepoints.
Why it matters: New commercial satellite imagery analyzed by the Center for Strategic and International Studies shows China has added antennas, dishes and towers at its Djibouti base near Camp Lemonnier, the U.S. military's main counterterrorism hub in Africa — a buildup a former Trump administration official says gives Beijing a direct window into U.S. Navy movements through the Red Sea, right as Xi Jinping heads to Washington.
Driving the news:
Satellite imagery reviewed by CSIS shows China's Djibouti base has added a 30-meter dipole antenna array covered by a dome, mobile satellite dishes, and four probable new 5G towers.
The base has also gained two new communications facilities since 2024, according to the imagery.
Morgan Murphy — a former Trump White House official who served as press secretary to Defense Secretary Mark Esper during Trump's first term — says the equipment points to a deliberate eavesdropping operation, not routine base upkeep.
It's not the first flashpoint at the base: in 2018 the Pentagon said China aimed military-grade lasers at American C-130 pilots landing at Camp Lemonnier, causing minor eye injuries, which Beijing denied.
By the numbers:
6 miles — distance between China's upgraded base and the U.S.'s Camp Lemonnier.
30 meters — width of the dome-covered antenna array China installed.
4 — probable new 5G towers identified in the satellite imagery, plus 2 new communications facilities built since 2024.
~16% — share of global maritime trade that passes through the nearby Bab el-Mandeb Strait.
~33% — share of China's daily oil imports that flow from the Middle East, part of why the region matters to Beijing.
What they’re saying: "What China is clearly doing is building eavesdropping capabilities," Murphy said. "Beijing has clearly wiretapped the Red Sea. When you build a 30-meter satellite dish and cover it with a dome, so nobody can see where it’s pointing, it’s pretty clear you’re up to no good." He added: "This isn’t a supply depot — it’s a 50-yard line seat over America’s power projection and the U.S. Navy."
The other side: China’s Foreign Ministry, through spokesperson Guo Jian, said Beijing was "unaware of the specific situation" and described China as a "builder of international peace," per Reuters.
What’s next:
Xi Jinping is due at the White House on Sept. 24 — the report lands just days before that visit, and it's an open question whether the base comes up in his meeting with Trump.
The bottom line: A quiet infrastructure upgrade 6 miles from a U.S. base is now a live diplomatic wrinkle heading into a high-profile Trump-Xi meeting.
