On April 28 the State Department issued a joint statement expressing solidarity with Panama after an increase in detentions of Panama-flagged vessels at Chinese ports, calling the detentions an attempt to politicize maritime trade. The statement followed a sustained campaign of legal and political pressure that helped displace Chinese logistics operators from the Balboa and Cristóbal terminals, and it arrives amid a wider U.S. maritime posture that includes actions in the Strait of Hormuz, a new defense partnership with Indonesia, and pointed U.S. commentary about Peru’s Port of Chancay.
The five countries that cosigned the Panama declaration—Costa Rica, Bolivia, Paraguay, Guyana, and Trinidad and Tobago—may seem disparate, but each aligns with U.S. economic and security priorities in the hemisphere. Guyana is rapidly emerging as a light crude producer attracting downstream investment. Trinidad supplies petrochemical feedstocks such as urea and ammonia. Costa Rica runs one of the most technologically advanced Caribbean ports. Paraguay remains one of the few South American states that recognizes Taiwan. And Bolivia, though landlocked, matters for its vast lithium reserves.
The Panama episode caps months of U.S. pressure: bilateral security dialogues, politically charged audits of Chinese port concessions, and a Panamanian Supreme Court decision that removed Hong Kong–based CK Hutchison from operations and left terminals to a Maersk subsidiary. Those moves, together with earlier threats under the previous administration to intervene in canal affairs, complicate Washington’s current posture of defending Panama’s sovereignty and opposing the politicization of trade.
Bolivia’s presence in the statement is especially revealing. The Salar de Uyuni and other salt flats hold vast lithium reserves, but extraction is costly and technically demanding because of high magnesium-to-lithium ratios. Moving large quantities of lithium to Pacific ports and then through the Panama Canal adds further logistical cost. Bolivia’s new president, Rodrigo Paz, has replaced the state lithium company’s CEO, a sign he may be willing to revisit deals made with Chinese and Russian partners if Western capital can assure buyers and logistics. For Bolivia, signing a U.S.-led statement that elevates Panama as central to maritime trade is a low-cost diplomatic signal of alignment with Western market and logistics networks.
Taken together with U.S. measures in West Asia to restrict certain flows from the Persian Gulf, Washington’s diplomacy in the Caribbean points to a coherent strategic objective: redirecting energy, mineral, agricultural, and logistics flows away from Chinese influence and toward U.S.-aligned routes and partners. The so-called Donroe Doctrine reads less like benign regional integration and more like an effort to rewire supply chains, drawing capital and transport circuits away from Eurasian nodes and back to the Western Hemisphere.
Whether that effort will succeed is uncertain. It is notable, however, that the State Department is actively cultivating a maritime consensus among Latin American producers of energy feedstocks, agricultural commodities, and green metals—many of which have recently resisted Chinese investment. At the same time, U.S. naval deployments and diplomatic pressure signal that America is no longer projecting itself as a neutral guarantor of a global maritime commons. The older notion of universally free sea lanes is fraying as Washington reframes maritime order to serve strategic and commercial priorities.
In the short term this shift creates friction and instability in maritime governance and trade. That turbulence could be exploited by coastal states and other global powers, including China, able to leverage new chokepoints or regional influence. For now, however, the United States appears prepared to exploit the flux to secure reliable access to critical inputs and logistics for American energy, agricultural, and mining interests—using diplomatic leverage, legal measures, and military presence to reshape maritime trade across the Americas.
