COSCO Rejects U.S. Spy-Ship Claims as “Totally Unforeutunded” as Security Scrutiny Deepens Around Chinese Merchant Fleet

COSCO SHIPPING has issued an unusually forceful denial of U.S. allegations that some of its commercial vessels carry concealed signals-intelligence equipment capable of intercepting military communications. The accusations first surfaced September 1, when two anonymous senior U.S. administration officials told Reuters that COSCO had a long-running intelligence relationship with Beijing and that specialized equipment aboard its ships was being used near coastlines in North America, Europe and Asia. The officials did not identify any individual COSCO vessels, disclose the equipment involved or release public evidence supporting the claim. COSCO responded September 3 by calling the allegations “totally unfounded,” saying every communications, navigation, safety and operating system aboard its ships serves legitimate commercial purposes and that none is used to intercept military communications or gather intelligence. The state-owned shipping group also reserved the right to pursue legal action to protect its reputation.
COSCO Security Dispute Snapshot
Washington has made a serious intelligence allegation against one of the world's largest shipping groups, but the public record still contains a large gap between the accusation and evidence available to the maritime industry.
Two anonymous senior U.S. officials say some COSCO vessels collect military communications intelligence.
COSCO says onboard systems are used solely for commercial navigation, communications, safety and emergency response.
No vessel names, equipment models, photographs or technical evidence were released with the allegation.
COSCO SHIPPING and two related entities were added to the Pentagon list in January 2025.
COSCO SHIPPING Holdings reported approximately 3.66 million TEU of operated container capacity.
The Public Record So Far
Several separate security issues now surround COSCO. They are related politically, but they should not be treated as proof of one another.
| Issue | Public Status | U.S. Position | COSCO / China Position | Evidence Available Publicly | Commercial Significance |
|---|---|---|---|---|---|
| Concealed SIGINT Equipment | ALLEGATION Not independently established | Two senior U.S. officials say COSCO ships use sophisticated concealed systems to collect military communications. | COSCO says no onboard equipment is used to intercept military communications or gather intelligence. | No ship names, equipment types, imagery, technical characteristics or intelligence documents were publicly released. | Could increase scrutiny of COSCO vessels, port access, inspections, contracts and terminal relationships if supporting evidence emerges. |
| COSCO Corporate Response | CONFIRMED RESPONSE Sept. 3, 2026 | Original allegation was made through anonymous administration officials speaking to Reuters. | Company calls the allegations totally unfounded and reserves its legal rights. | COSCO issued a formal public statement denying the central allegation. | A categorical denial raises the stakes if U.S. authorities later publish vessel-specific evidence. |
| Pentagon 1260H Listing | CONFIRMED January 2025 | Pentagon designated COSCO SHIPPING and related entities as Chinese military companies operating directly or indirectly in the U.S. | The designation has been rejected by Chinese authorities as part of broader U.S. pressure on Chinese companies. | COSCO SHIPPING, COSCO SHIPPING North America and COSCO SHIPPING Finance appear on the published 1260H list. | Carries procurement, compliance and reputational consequences but is not itself the same thing as OFAC sanctions. |
| Merchant-Fleet Intelligence Research | SECURITY CONTEXT U.S. Naval War College | A 2025 study argued the PLA has incentives to exploit distant-water fishing and merchant vessels for overseas ISR. | COSCO denies that its commercial ships perform the intelligence activity alleged this week. | The study cites Chinese military writings and maritime-militia structures, but does not publicly prove the new COSCO SIGINT allegation. | Helps explain why commercial Chinese vessels are receiving greater defense and intelligence scrutiny. |
| Long Beach Terminal Divestment | CONFIRMED HISTORY $1.78B Sale | National-security agreement tied to COSCO's acquisition of OOIL required divestment of Long Beach Container Terminal. | OOCL remained a long-term commercial customer after the terminal changed ownership. | Sale closed pursuant to a formal agreement involving DHS and DOJ. | Demonstrates that U.S. security concerns can ultimately reshape terminal ownership without removing the shipping service itself. |
| Section 301 Vessel Fees | SUSPENDED Through Nov. 9, 2026 | USTR created fees targeting Chinese vessel owners/operators and Chinese-built ships as part of its maritime and shipbuilding action. | COSCO has previously argued the measures distort competition and disrupt global shipping. | USTR formally suspended the action for one year. No fees currently accrue. | If the suspension is not extended, COSCO's U.S. network could again face potentially large per-voyage exposure. |
| September U.S.-China Talks | POLICY WINDOW Before November Deadline | Shipping, trade restrictions and national security sit within a wider U.S.-China negotiating relationship. | Beijing continues to oppose what it describes as politicisation of Chinese commercial companies. | No public announcement links the COSCO intelligence allegation directly to a new shipping restriction. | Security accusations arriving shortly before the vessel-fee suspension deadline increase uncertainty for 2027 freight contracting. |
