DJIBOUTI — The two countries keep dozens of intercontinental nuclear missiles pointed at each other’s cities. Their frigates and fighter jets occasionally face off in the contested waters of the South China Sea.
With no shared border, China and the United States mostly circle each other from afar, relying on satellites and cybersnooping to peek inside the workings of each other’s war machines.
But the two strategic rivals are about to become neighbors in this sun-scorched patch of East African desert. China is constructing its first overseas military base in Djibouti — just a few miles from Camp Lemonnier, one of the Pentagon’s largest and most important foreign installations.
With increasing tensions on China’s island-building efforts in the South China Sea, US strategists worry that a naval port so close to Camp Lemonnier could provide a front-row seat to the staging ground for US counterterrorism operations in the Arabian Peninsula and North Africa.
“It’s like having a rival football team using an adjacent practice field,” said Gabriel Collins, an expert on the Chinese military and a founder of the analysis portal China SignPost. “They can scope out some of your plays. On the other hand, the scouting opportunity goes both ways.”
Established after the terrorist attacks of Sept. 11, 2001, Camp Lemonnier is home to 4,000 personnel. Some are involved in highly secretive missions, including targeted drone killings in the Middle East and the Horn of Africa, and the raid last month in Yemen that left a member of the Navy SEALs dead. The base, which is run by the Navy and abuts Djibouti’s international airport, is the only permanent US military installation in Africa.
Beyond surveillance concerns, US officials, citing the billions of dollars in Chinese loans to Djibouti’s heavily indebted government, wonder about the long-term durability of an alliance that has served Washington well in its global fight against Islamic extremism.
Just as important, experts say, the base’s construction is a milestone marking Beijing’s expanding global ambitions — with potential implications for the United States’ longstanding military dominance.
“It’s a huge strategic development,” said Peter Dutton, professor of strategic studies at the Naval War College in Rhode Island, who has studied satellite imagery of the construction.
“It’s naval power expansion for protecting commerce and China’s regional interests in the Horn of Africa,” Dutton said. “This is what expansionary powers do. China has learned lessons from Britain of 200 years ago.”
Chinese officials play down the significance of the base, saying it will largely support antipiracy operations that have helped quell the threat to international shipping once posed by marauding Somalis.
“The support facility will be mainly used to provide rest and rehabilitation for the Chinese troops taking part in escort missions in the Gulf of Aden and waters off Somalia, U.N. peacekeeping and humanitarian rescue,” the Defense Ministry in Beijing said in a written reply to questions.
In addition to having 2,400 peacekeepers in Africa, China has used its vessels to escort more than 6,000 boats from many countries through the Gulf of Aden, the ministry said. China’s military has also evacuated its citizens caught in the world’s trouble spots. In 2011, the military plucked 35,000 from Libya, and 600 from Yemen in 2015.
As China’s navy has assumed these new roles far from home, its commanders have struggled to maintain vessels and resupply them with food and fuel.
Captain Liu Jianzhong, a former political commissar of a Chinese destroyer plying the Gulf of Aden, said the lack of a dedicated port in the region took a toll on personnel forced to spend long stretches at sea.
“For six months, we didn’t reach the shore, and a lot of sailors had physical and psychological problems,” he told the state-run China Military Online. To that end, the new base will include a gym, the ministry said.
Dutton said Beijing would probably try to “acclimatize” the world by using the facility for commercial purposes when it begins operating this year and then gradually increase the number and variety of warships that dock there.
“It will be relatively incremental in the forward deployment of naval power. You are not going to see a Yokosuka,” he said, referring to the base for the US 7th Fleet in Japan.
In its written answers, the ministry said that China was not budging from its “defensive” military policy and that the base did not indicate an “arms race or military expansion.”
