China is expanding the reach of its first overseas military base

China’s first overseas military base in Djibouti is acquiring capabilities that could make it considerably more useful beyond its East African host.

Since mid-2024, two new communications facilities have appeared at the People’s Liberation Army’s (PLA) base near the Bab al-Mandab, the roughly 20-mile-wide strait through which an estimated 16% of global maritime trade passes, according to the Center for Strategic and International Studies (CSIS). Satellite imagery analyzed by CSIS shows antennas, satellite communications equipment, and towers believed to support 5G networks, strengthening communications while potentially giving Beijing new means of observing military activity across the region.

The capabilities arrive amid heightened military activity around the Red Sea, where Houthi attacks have disrupted commercial shipping and U.S. and allied forces have conducted operations.

“The new equipment will allow the PLA to maintain secure communications between its assets operating in the region and command headquarters back in mainland China,” Aidan Powers-Riggs, Associate Fellow for China Analysis at CSIS and an author of the report, told The Beiruter.

The upgrades essentially give China's military a better set of eyes and ears to help it operate in a challenging environment.

Once associated primarily with logistical support, China’s Djibouti base is assuming a more sophisticated role as Beijing pushes its military operations farther overseas.

New eyes and ears

China opened its Djibouti base in August 2017, giving the PLA its first permanent military facility abroad. Initially supporting anti-piracy patrols in the Gulf of Aden, peacekeeping and evacuations, its capabilities have developed considerably since then.

“The base has been gradually expanding since it first opened in 2017, including a pier for naval vessels, a small airstrip for drones and helicopters, and even an underground facility,” Powers-Riggs said.

It's possible that these upgrades will allow the base to take on more of an intelligence mission, in addition to its established logistics and support role.

The newest infrastructure is concentrated in two communications facilities at opposite ends of the base. According to the September 2026 CSIS report Extended Range: China Upgrades Its Military Base in Djibouti, the larger site contains several types of antennas capable of communicating over different distances, three mobile satellite dishes and four towers believed to support 5G communications. A second site adds another set of communications equipment.

The systems give the PLA multiple ways to communicate with ships and aircraft and maintain secure links with military headquarters in China, reducing its dependence on any single communications channel.

But the same infrastructure could also allow China to gather information about other military activity in the region.

According to CSIS, some equipment could support signals intelligence by intercepting or tracking other militaries’ communications. Even when encrypted, a signal’s origin, destination and frequency can provide clues about military locations and activity.

A base beside the chokepoint

The geography surrounding China’s Djibouti base is central to what Beijing can do from it. The Bab al-Mandab connects the Red Sea with the Gulf of Aden and ultimately the Indian Ocean, forming a critical link in the maritime route between Europe and Asia.

For China, whose economy remains heavily dependent on seaborne trade, access to that corridor offers more than proximity to commercial shipping. It also gives Chinese forces a foothold near waters that have become an active theater of military operations.

Since late 2023, Houthi attacks on commercial vessels have forced shipping companies to divert around southern Africa and prompted repeated U.S. and allied military operations in and around the Red Sea. More than two years later, traffic has yet to fully recover. Ship passages through the Bab al-Mandab remained at roughly half their 2023 level as of April 2026, according to the International Monetary Fund.

“The Djibouti base gives the PLA a crucial foothold beside one of the world's most important maritime chokepoints,” Powers-Riggs said.

Having a support base there allows China to maintain a consistent military presence in the region that can quickly respond to situations.

The same geography puts China unusually close to other militaries. The United States, France, Italy, and Japan all operate bases within 10 miles of the Chinese facility, according to CSIS, placing considerable foreign military activity within reach.

But Djibouti is not only giving China a vantage point on other forces. It is also helping the PLA sustain its own presence in the region for longer.

Powers-Riggs pointed to the PLA Navy’s Gulf of Aden Naval Escort Task Force, whose deployments have increased from roughly four months to around 10 months since 2024.

Longer rotations do not by themselves demonstrate a change in the base’s mission, but they indicate a greater capacity to keep Chinese naval forces operating far from home. 

A wider military footprint

Although Djibouti remains unusual in China’s overseas military presence, it is becoming less isolated.

Beijing has spent years securing access to ports abroad without necessarily turning them into conventional Chinese military bases. Chinese companies have developed or operated facilities including Gwadar in Pakistan and Hambantota in Sri Lanka, while the PLA Navy has used foreign ports to resupply during distant deployments.

This approach has allowed China to expand the infrastructure available to its navy while remaining cautious about facilities explicitly identified as Chinese military bases, which can carry greater political costs for host governments and attract scrutiny from Washington.

There are signs, however, that the geography of China’s military access is widening.

“Just last week China opened its first overseas air base in Laos, only its second formally acknowledged overseas military facility after Djibouti,” Powers-Riggs said. China also has access to Cambodia’s Ream Naval Base, where Chinese warships have maintained a recurring presence.

China is clearly looking to gradually expand its overseas military footprint, although Beijing is likely to proceed cautiously to avoid scrutiny and pushback from Washington.

Djibouti offers a glimpse of what such an expansion may look like in practice. China does not need a network approaching the size of America’s overseas basing system for individual facilities to become more consequential. A small number of well-positioned bases capable of sustaining forces, maintaining secure communications and gathering information can give the PLA considerably greater reach than their number alone would suggest.

As China sends its forces farther from its own shores, Djibouti shows how much more valuable an overseas base can become without China having to build another one.
