The Trump administration is escalating its warning to Peru, arguing that China’s growing control over a massive Pacific port could undermine the country’s sovereignty.

After a Peruvian court restricted the government’s regulatory oversight of the Chinese built Port of Chancay, U.S. officials responded with unusually direct language.

The State Department’s Bureau of Western Hemisphere Affairs said it was “concerned about latest reports that Peru could be powerless to oversee Chancay, one of its largest ports, which is under the jurisdiction of predatory Chinese owners.”

The bureau did not stop there. “We support Peru’s sovereign right to oversee critical infrastructure in its own territory,” the statement said. “Let this be a cautionary tale for the region and the world: cheap Chinese money costs sovereignty.”

A Court Ruling That Changed the Equation

On Jan. 29, a lower court judge ordered Peruvian authorities to refrain from exercising “powers of regulation, supervision, oversight and sanction” over the port in Chancay.

That ruling effectively limited the ability of Peru’s regulator, Ositran, to supervise the $1.3 billion deep water facility, which is majority owned by China’s state owned shipping giant Cosco.

For Washington, this was more than a legal technicality. It raised fundamental questions about who ultimately controls one of Peru’s largest and most strategic infrastructure projects.

The Associated Press described the U.S. response as a “blunt warning” that China was costing Peru its sovereignty by “solidifying control over the South American nation’s critical infrastructure.”

A Strategic Asset, Not Just a Port

Chancay is Latin America’s deepest port and covers about 445 acres of Peruvian territory. It can berth some of the world’s largest cargo ships traveling between Asia and South America.

Analysts say it could redirect trade across the South Pacific.

Asia analyst Gordon Chang warned that the issue is not simply commercial. “We know Beijing considers ports to be dual use and strategic,” he said.

He also cautioned about what that could mean in a crisis. “In times of war, China will not allow its port operations to load, unload, or service American ships or ships coming from or going to U.S. ports.”

That kind of leverage, critics argue, is precisely why Chinese infrastructure investments raise alarms in Washington.

China ‘Grasping the Sinews’ of Infrastructure

Jack Burnham, senior analyst in the China program at the Foundation for Defense of Democracies, described the port as central to Beijing’s regional strategy.

“The Chancay port is a keystone in China’s investment in Latin America,” he said, noting that its size and proximity provide “a bridge across the Pacific and access to another market to fuel Beijing’s export driven economic engine.”

Burnham added that “China’s investment in Peru is predicated on Beijing grasping the sinews of Lima’s critical infrastructure to gain influence.”

With the lower court ruling limiting effective oversight, he warned that China gains access to one of the region’s largest critical infrastructure projects “from which it could exercise significant control.”

From this perspective, the U.S. warnings are not exaggerated. They are a recognition of how economic footholds can evolve into strategic leverage.

Peru’s Regulator Fights Back

Peru’s transport infrastructure regulator, Ositran, has said it will appeal the ruling.

Verónica Zambrano, president of Ositran, pointed out that if the ruling stands, “(Cosco Shipping) would be the only company providing services to the public that could not be supervised.”

She emphasized that although the port is privately owned, it occupies Peruvian territory and should be subject to national oversight and user protection standards.

The court’s restriction on “regulation, supervision, oversight and sanction” is precisely what has alarmed U.S. officials, who argue that no sovereign nation should lose the ability to monitor such a critical asset.

China Rejects the Accusations

Beijing strongly rejected the U.S. statements.

Foreign Ministry spokesperson Lin Jian said, “China firmly opposes and strongly deplores the U.S.’s blatant rumor mongering and smearing of Chancay port.”

Cosco also insisted that the ruling “in no way involves aspects of sovereignty” and that the port remains “under the jurisdiction, sovereignty and control of Peruvian authorities, subject to all Peruvian regulations.”

Chinese officials argue the project will cut shipping times to 23 days, reduce logistics costs by more than 20 percent, generate billions of dollars annually for Peru, and create more than 8,000 direct jobs.

A Warning to the Entire Region

The Trump administration sees the issue as part of a broader competition for influence across Latin America.

The State Department’s language was not subtle. It described the port as being “under the jurisdiction of predatory Chinese owners” and repeated its support for “Peru’s sovereign right to oversee critical infrastructure in its own territory.”

By calling it a “cautionary tale for the region and the world,” Washington made clear that this warning extends beyond Peru.

Supporters of the administration argue that China’s model is consistent. Offer large loans. Build strategic infrastructure. Gain majority ownership. And when legal or political conditions allow, limit local oversight.

From that standpoint, the warning is justified. Sovereignty is not lost overnight. It erodes step by step when control over critical infrastructure shifts away from national authorities.
