Beijing has transformed the Red Sea into a dangerous surveillance hub, a former Pentagon official warned Sunday, after a new report revealed upgrades to China’s military footprint just six miles from a key $66 million-a-year U.S. military base in Djibouti, Africa.

The report by the Washington-based Chinese President Xi Jinping's visit to the White House on Sept. 24. Beijing's intelligence-gathering capabilities are already under renewed scrutiny.

"What China is clearly doing is building eavesdropping capabilities. That seems to be their aim," said Camp Lemonnier — the primary U.S. counterterrorism hub in Africa — and near French, Italian and Japanese installations, the site has a history of friction with U.S. forces.

"We are just right around the corner from China, and yet it's not a cooperative relationship," Murphy explained.

"Back in 2018, they lasered two of our C-130 pilots' eyes who suffered lasting damage from that incident. Beijing denied it, of course, but we know the truth."

During the 2018 incident, the Pentagon had formally complained to China after military-grade lasers were pointed at American pilots attempting to land at Camp Lemonnier, causing minor injuries.

While Beijing dismissed the allegations as "groundless accusations," the confrontation underscored the potential for friction between military forces operating from nearby bases.

"China has one overseas base. The United States has more than 128 — by some counts, over 700 installations around the world," Murphy said.

"So it's significant that China has chosen to place its only overseas base six miles from ours in Djibouti. It is hugely strategically important, which is why, of course, we're there."

"It's our only base on the continent of Africa," he said, noting that it shares a "parking lot" with Japanese and Italian bases.

"At $66 million a year, it's the best money Americans spend on our defense budget, full stop."

The Bab el-Mandeb Strait is a choke point for nearly 16% of global maritime trade and, with significant crude shipments, Houthi attacks and pipeline disruptions have fueled a regional military buildup.

"Interference by China is in their strategic interest. They don't want to see the United States able to control their oil supply," Murphy said.

"China is far more reliant on Middle Eastern oil than the United States. China imports a huge portion — around 33% or more — of their daily oil needs and is highly reliant on long sea lines. You are seeing this muscle-flexing because they are far more reliant on Middle Eastern oil than we are."

"Having intelligence is one thing, but you must have the ability to act on it. You need assets in the region," Murphy said.

"China doesn't have major combat assets outside their region because they lack a blue-water navy to project power outside the first island chain yet.

"That is coming, and they are working towards it quickly. Americans can take comfort in the fact that they don't have that capacity today, but we must stay alert because the only thing that subdues a threat is a ready posture," he concluded.
