Key Facts

—The defence. China calls its inspections of Panama-flagged ships routine safety checks.

—The rebuttal. It rejects US and Panamanian claims that it is weaponising shipping.

—The claim. Beijing says such vessels had the highest share of accidents in its waters this year.

—The trigger. Detentions spiked after Panama voided a Chinese-linked canal port concession.

—The fallout. Owners have begun shifting vessels off Panama’s registry to other flags.

China has publicly defended its inspections of Panama-flagged ships as routine safety checks, pushing back against US and Panamanian accusations that it is using shipping as a political weapon.

The statement came from Beijing on Monday. A foreign ministry spokesman said the measures were lawful and meant to protect navigation and the marine environment.

For a foreign investor, the dispute is a warning. It shows how a court ruling over two ports can ripple into shipping costs and global supply chains.

Why China is inspecting Panama-flagged ships

Beijing frames it as safety. It says port-state inspections are a normal tool for any country managing foreign vessels calling at its ports.

It offered a specific reason. Chinese data, the spokesman said, showed such vessels were involved in several serious accidents in Chinese waters this year.

That, Beijing argues, made Panama the flag state with the highest share of incidents, justifying tighter checks under international rules.

China insists it targets no country. It says the inspections comply with its own laws and global conventions and are not aimed at any particular flag.

What critics say about the Panama-flagged ships row

The timing draws suspicion. The surge in inspections began around the time Panama’s Supreme Court voided a Chinese-linked port concession at the canal.

Washington calls it retaliation. A senior US maritime official has described the campaign as a weaponisation of safety inspections aimed at punishing Panama.

The numbers were striking. By independent count, detentions in a two-month spring window exceeded the total for all of the previous year.

Several neighbours backed Panama. A group of Latin American states joined the United States in urging Beijing to respect national sovereignty over shipping.

For an outside reader, the real cost is trust. As detentions mounted, some owners began moving their vessels off Panama’s flag to other registries.

The root of the quarrel is the ports. Panama’s top court struck down a Hong Kong company’s concession to run terminals at both ends of the canal, calling it unconstitutional.

A planned sale sharpened tensions. Those terminals were set to pass to a United States-led consortium, a shift Washington cast as proof of its leverage.

Beijing’s response went beyond ships. A large Chinese state shipping line briefly suspended a container service at one canal port, and new investment was put on hold.

The stakes are global. The canal handles a sizeable slice of world trade, and the United States is by far its biggest single user.

Panama’s flag is a business in itself. It runs the world’s largest ship registry, an open system whose value rests on being cheap and trouble-free to use.

That openness is now a weakness. A flag flown by thousands of foreign owners can be pulled into disputes Panama itself had no part in starting.

The forward signal is the flag flight. Whether owners keep leaving Panama’s registry will show how much lasting damage the standoff has done.

The legal fight is far from over. The former port operator has launched arbitration seeking billions in damages, while Panama prepares a fresh tender for the two terminals.

Frequently Asked Questions

Why is China inspecting Panama-flagged ships?

China says the inspections are routine port-state safety checks, lawful under international conventions and aimed at protecting navigation and the marine environment. It says Panama-flagged vessels were involved in several serious accidents in Chinese waters this year, giving them the highest share of incidents.

Why do the US and Panama object?

They argue the sharp rise in detentions is political retaliation, since it began around the time Panama’s Supreme Court voided a Chinese-linked canal port concession. A US maritime official has called it a weaponisation of inspections intended to punish Panama.

What is the wider impact?

The detentions delayed voyages and raised costs, and some owners began shifting vessels off Panama’s registry to other flags. Because Panama-flagged ships carry a meaningful share of world trade, a sustained squeeze could ripple through global supply chains.
