On April 28 the State Department issued a joint statement “in solidarity with Panama” after a spate of detentions of Panama‑flagged vessels at Chinese ports, calling Beijing’s actions “a blatant attempt to politicize maritime trade.”
That diplomatic note did not come out of nowhere. It follows a targeted campaign by U.S. and Panamanian officials to push Chinese logistics operators out of the Balboa and Cristobal terminals and sits alongside a broader maritime posture that has included a U.S. blockade in the Strait of Hormuz, a new defense partnership with Indonesia, and public pressure over Peru’s Port of Chancay.
The five co‑signatories on the Panama statement—Costa Rica, Bolivia, Paraguay, Guyana, and Trinidad and Tobago—may look like an eclectic grouping, but their inclusion maps tightly onto long‑term American economic and strategic priorities in the hemisphere. Guyana is rapidly becoming a major light‑crude producer and attracting downstream investment as Washington tightens links with West Asian suppliers. Trinidad provides petrochemical feedstocks such as urea and ammonia. Costa Rica hosts one of the region’s most technologically advanced ports. Paraguay remains one of the few South American states that recognizes Taiwan. And Bolivia, landlocked though it is, sits on the world’s largest lithium reserves.
Washington’s pressure on Panama followed a politically charged Panamanian audit and court decision that removed Hong Kong‑based CK Hutchison from port operations and resulted in a Maersk subsidiary taking over terminals—an outcome that dovetailed with prior U.S. warnings about preventing Chinese influence near the Canal. Given that context, State Department appeals to Panama’s “sovereignty” and cautions against “politicization” ring hollow for many observers.
Bolivia’s appearance on the list is especially telling. Its lithium-bearing brines have some of the world’s largest reserves, but high magnesium‑to‑lithium ratios mean extraction and refining are capital‑intensive and technically challenging. Moving bulk lithium over difficult terrain to Chilean ports and then through the Panama Canal adds significant logistical costs to every ton destined for EV batteries and grid storage. Bolivia’s new president, Rodrigo Paz, has signaled a willingness to reassess deals made with China and Russia under his predecessor; replacing the head of the state lithium firm Yacimientos de Litio Bolivianos was an early sign of that pivot. For Bolivia, endorsing a U.S.‑led statement that calls Panama a “pillar of our maritime trading system” is a low‑cost diplomatic signal that it will play by Western‑oriented rules in exchange for access to buyers and logistics support.
Seen alongside U.S. operations in the Persian Gulf—where American forces have constrained flows of certain crude grades to Asia—the State Department’s moves in the Caribbean point to a coordinated effort to redirect trade and capital. This pattern looks less like a pure defense of freedom of navigation and more like an attempt to reconfigure maritime routes and partnerships so that energy, agricultural, and critical‑mineral inputs flow more reliably to Western markets and allied firms and less to Chinese networks.
This strategic reorientation—labeled by some commentators the “Donroe Doctrine”—is not merely about benign economic integration. It is an attempt to compel capital back to the Western Hemisphere by building alternative maritime corridors, logistics dependencies, and regulatory alignments. U.S. diplomacy is actively encouraging Latin American producers of oil, petrochemicals, port services, and “green” metals to adopt policies and partners compatible with American rules and markets; many of those producers have recently spurned Chinese investment offers.
Anyone still treating the United States as an impartial guarantor of a neutral maritime commons is overlooking how military and diplomatic tools are being wielded in parallel. While Washington accuses China of politicizing trade in the Americas, U.S. naval actions in West Asia—including seizures of vessels—and sustained diplomatic pressure across the Caribbean and South America illustrate a reciprocal politicization of maritime access.
The shift has deeper roots. When U.S. policy signaled a reduced commitment to policing the Persian Gulf—undermining the post‑Carter Doctrine idea of a universally protected maritime commons—that weakened the norms supporting an open, global shipping order. Over time that erosion may benefit regional coastal powers, including China. In the near term, however, it has introduced instability into the maritime system—instability the State Department appears ready to exploit to secure American energy, agricultural, and mining interests by reconfiguring trade routes and partnerships across the Americas.
Seen in this light, recent statements and maneuvers are best understood as strategic maneuvering: a concerted effort to reshape where and how goods move, who controls critical logistics nodes, and which markets and currencies dominate regional trade—not simply a neutral defense of maritime law.
