Panama announced yesterday it will sanction a Chinese consortium for alleged breaches on a canal-related infrastructure project as detentions of Panamanian-flagged vessels in Chinese ports continue. The move comes after a sharp rise in inspections that began in March, when 93 Panamanian ships faced holds in China. Eleven of 20 vessels detained between April 1 and 4 flew the Panamanian flag, or 55 percent of the total in that period.
The actions mark the latest escalation in a standoff triggered by Panama’s Supreme Court ruling that declared unconstitutional the concessions held by Hong Kong-based CK Hutchison for the ports of Balboa and Cristóbal at the entrances to the Panama Canal. Panama took control of the terminals in February and granted temporary operating rights to Danish firm Maersk and Swiss-Italian MSC. China has responded with intensified port state control inspections on Panamanian vessels and, according to the Financial Times, pressed Maersk and MSC to cease operations at the canal ports.
The rise in detentions has drawn international attention because Panama operates the world’s largest merchant ship registry. The flagged fleet carries a significant share of global container traffic, including goods moving through the Panama Canal. Officials in Panama say the inspections far exceed historical norms and appear linked to the port dispute.
President José Raúl Mulino has acknowledged the increase in detentions but stressed Panama wants to avoid open confrontation with Beijing. “We do not want problems with China, but we will not allow these things to continue indefinitely,” Mulino said in early April. The government has pressed Chinese authorities through diplomatic channels while insisting the detentions must end.
Multiple governments have publicly backed Panama. The United States Federal Maritime Commission and Secretary of State Marco Rubio raised concerns that China is using economic tools to undermine the rule of law. Governments of Israel, Ukraine, Honduras, Peru, and Paraguay issued similar statements calling the inspections a threat to global supply chains.
Costa Rica joined the chorus earlier this month. Its Ministry of Foreign Affairs stated that the government “expresses its deep concern and the firmest condemnation for the commercial measures imposed by the People’s Republic of China on Panamanian vessels due to the delays and arbitrary and unjustified inspections in Chinese ports, because they put global trade at risk.”
The statement reaffirmed Costa Rica’s “unconditional support and solidarity with the brotherly people and government of the Republic of Panama” and its commitment to international maritime law under the United Nations Convention on the Law of the Sea.Panama’s Foreign Ministry welcomed the expressions of support, describing them as a defense of free navigation and stable trade routes.
The dispute traces back to long-standing contracts first awarded to CK Hutchison in 1997. Panama’s Supreme Court found the extensions granted in later years violated constitutional requirements on public contracting. After the ruling, Panama seized the terminals and installed temporary operators. China has denied any political motive behind the inspections, calling them routine safety checks under international maritime conventions.
Data from the Tokyo Memorandum of Understanding on port state control show the pattern clearly. In January and February, Panama-flagged vessels accounted for roughly 20 to 23 detentions per month in Chinese ports. The figure jumped to 93 in March and remained elevated in the first week of April, with 18 Panamanian ships held between April 1 and 7.
Shipping industry sources report the holds typically last one to four days and involve additional fire-safety, pollution-prevention, and lifesaving-equipment reviews. No vessels or cargo have been seized, but the delays disrupt schedules and raise costs across supply chains.
Panama’s latest sanction announcement targets a Chinese consortium involved in a major bridge project spanning the canal. Authorities cited alleged labor and contractual violations. Details of the specific penalties remain under review, but the step signals Panama’s willingness to respond on multiple fronts.
What happens next remains unclear. Panama continues diplomatic talks with Beijing while keeping an eye on the detention numbers. Mulino has said the government will not tolerate indefinite holds but prefers a negotiated resolution. Regional observers watch closely to see whether the measures ease or whether further retaliation follows.
The case shows the Panama Canal’s role as a critical chokepoint in global trade and the vulnerability of even the largest ship registries to geopolitical friction.
