A Peru court has handed the state full power to oversee the China-run Chancay port, reversing an earlier ruling that had kept regulators out. It is the second courtroom defeat for the Chinese operator in a week.

The decision settles the bigger of two legal fights over who governs one of Latin America’s most important new trade gateways. It tilts firmly toward the state.

For a reader abroad, the case turns on a deceptively simple question. Who makes the rules when private foreign money builds infrastructure that the public relies on?

What the Chancay port ruling decided

Lima’s Second Constitutional Chamber overturned a January decision by a lower court. That earlier ruling had ordered the transport regulator, known as Ositrán, to refrain from supervising the terminal.

The higher court threw out the challenge brought by the operator, Cosco Shipping. It found the company had shown no real threat to its rights that would justify blocking the regulator.

The heart of the reasoning is a category. Because the port is used by the public, the court held, the company running it counts as a service provider and falls under the regulator’s authority.

Crucially, that holds even though Chancay was built entirely with private money and without a state concession. Public use, not ownership, is what triggers oversight.

Why this fight matters more than the last one

An earlier ruling had already handed the state a narrow win on pricing at the port. But this case is broader and weightier.

The earlier decision covered only the regulator’s power to review tariffs. This one settles its full authority to regulate, supervise, inspect and penalise how the terminal operates day to day.

Cosco had argued the opposite with force. It said a privately financed port granted no state concession should sit outside the regulator’s reach, except on tariffs in narrow circumstances.

The court disagreed on the principle itself. That makes the ruling a precedent for every privately built asset that serves the public, well beyond this one terminal.

The geopolitics behind the docket

Chancay is no ordinary terminal. The roughly one-and-a-third-billion-dollar deep-water port opened in late 2024 and can take some of the largest ships afloat, cutting sailing time to Asia to around twenty-three days.

It is majority-owned by a Chinese state shipping group, which is why Washington watches it closely. US lawmakers have warned that the port could serve Chinese spying or future military use, claims Beijing rejects.

The ruling was the second legal blow to Cosco in a week. Days earlier, a court in Chancay upheld a market investigation by the competition agency, rejecting another company challenge.

The forward signal sits with the next government. Peru elects a new president who takes office in late July, and how firmly the state now asserts control at Chancay will test where the country leans between Beijing and Washington.

For investors, the ruling cuts two ways. It removes a cloud over how Chancay will be governed, which brings clarity, yet it also confirms that private builders here cannot escape the state’s reach.

Cosco can still fight specific decisions later. The court left open the ordinary administrative route to challenge any single regulatory act it believes oversteps, once such an act actually exists.

What it lost is the attempt to shut the regulator out in advance. That pre-emptive shield is gone, and the state now sits inside the port’s affairs rather than outside them.

What did the Chancay port ruling say?

A Lima appeals court gave Peru’s transport regulator, Ositrán, full authority to regulate and supervise the Chancay port, overturning a January decision that had ordered it to stand back. It threw out the legal challenge brought by the Chinese operator Cosco Shipping.

Why is the state allowed to regulate a private port?

The court held that because the port is used by the public, the company running it counts as a service provider subject to state oversight. Public use, rather than ownership, is what triggers regulation, even without a concession.

Why does the Chancay port matter globally?

Chancay is a deep-water hub that reroutes South American trade toward Asia and is majority-owned by a Chinese state group. That has made it a focus of the wider contest between China and the United States in Latin America.

The court gave Peru's transport regulator, Ositrán, full authority to regulate, supervise, inspect, and penalize how the Chancay port operates day to day. It overturned a January decision that had ordered the regulator to stand back, and threw out Cosco Shipping's legal challenge entirely.

The court ruled that public use, not ownership, is what triggers state oversight, so because the port serves the public, the company running it counts as a service provider under the regulator's authority. That principle applies even though Chancay was built entirely with private money and without a state concession.

Chancay is a roughly $1.3 billion deep-water port that reroutes South American trade toward Asia, cutting sailing time there to around 23 days. It is majority-owned by a Chinese state shipping group, which is why US lawmakers have been watching it closely and warning about potential security concerns that Beijing rejects.
