China detains surge of Panama-flagged ships as Hutchison port tensions escalate

Chinese Port State Control (PSC) authorities sharply increased detentions of Panama-flagged ships in March 2026, raising industry concerns about possible political pressure on inspections, according to The Maritime Telegraph . Data from the Tokyo MOU show 179 vessel detentions across the Asia-Pacific region last month, including 123 in Chinese ports. Of these, 91 sailed under the Panama flag, an unusually dominant share that has drawn attention from regulators and shipping executives.

 

The spike contrasts with earlier months. In January and February combined, Panama-flagged vessels accounted for far fewer detentions than ships under other registries. The sudden shift followed controversy around the transfer of port concessions at Balboa and Cristobal operated by CK Hutchison, fueling speculation that inspections may now carry geopolitical weight.

 

Laura DiBella, chair of the Federal Maritime Commission, warned that the trend appears to target vessels that move a large share of U.S. containerized cargo. She said the pattern could create strategic and commercial risks for global shipping flows.

 

Detained ships included containerships, tankers, and bulk carriers. Even some operated by Chinese owners under the Panama registry. Beijing did not confirm any link between inspections and the port dispute but rejected U.S. criticism tied to canal-related developments.

 

For shipping CEOs, the message is clear: inspection patterns in key Asian ports may now reflect broader strategic friction, not only technical compliance risk.
