China's First Naval Visit to Uruguay Brings Hospital Ship Diplomacy Into US Rivalry

A Four Day Stop in Montevideo Carries a Wider Message

The Chinese naval hospital ship Silk Road Ark arrived in Montevideo last Tuesday for a four day technical stop, making the first visit by a Chinese naval vessel to Uruguay. The stop brought Beijing's military outreach to a country between Brazil and Argentina at a sensitive moment in the competition between China and the United States for influence in Latin America.

The vessel's immediate business was replenishing supplies. Its arrival also came barely two weeks after US forces captured Venezuelan leader Nicolas Maduro earlier in January, as President Donald Trump sought to restore Washington's strategic sway in the region. A ship equipped to provide medical care has therefore become part of a much larger story about naval access, trade and the freedom of Latin American governments to choose their international partners.

Cui Shoujun, a professor and deputy director of the Institute of International Development Studies at Renmin University, interpreted the visit as evidence that Beijing was continuing its regional military exchanges despite the American operation in Venezuela. He said:

The port call indicates that China's naval exchanges with South American countries remained unaffected.

As of January 26, 2026, the Montevideo visit fits into two parallel developments: China is building relationships through trade, infrastructure and military contacts, while the Trump administration is seeking to limit the presence of powers from outside the Western Hemisphere. Uruguay's ties with Beijing give this brief naval stop a diplomatic setting that extends well beyond the port itself.

Why Uruguay Matters to Beijing

Uruguay's position between Brazil and Argentina, South America's two largest economies, gives it economic and geopolitical importance. China has deepened its relationship with the country through the Belt and Road Initiative and what Beijing describes as a "comprehensive strategic partnership." The partnership provides a political framework for closer cooperation alongside the economic relationship.

President Yamandú Orsi met Chinese Vice Premier Ding Xuexiang last November and expressed readiness to deepen coordination with China. Orsi described the principles he wanted that cooperation to support as:

free and open international trading system and multilateralism.

Multilateralism means countries working through shared institutions and agreements, rather than leaving decisions to a single powerful government. For Uruguay, Orsi's statement places the relationship with China within a wider commitment to international trade and cooperation.

Trump's approach puts a different priority at the center of American policy: US dominance in the Western Hemisphere. His national security strategy explicitly calls for limiting the presence of countries from outside the region. Uruguay's closer relationship with Beijing therefore sits alongside an American policy seeking to restrict the strategic reach of outside powers.

How the Hospital Ship Mission Developed

Silk Road Ark is one of China's three hospital ships of 10,000 tons. China's hospital ship deployments have regularly provided medical care on "Harmony" missions across Africa, the Americas, Asia and the Pacific since 2010. These voyages combine a practical service with contact between the Chinese military and the countries it visits.

The current deployment, "Harmony 2025," began last September. Its arrival in Uruguay continues a mission that was already under way before the US operation in Venezuela. Hospital ship diplomacy is a form of soft power: a country seeks goodwill and stronger relationships through useful services and cooperation.

The sequence leading to the Montevideo stop brings the diplomatic and military developments into focus:

• Since 2010: Chinese hospital ships have regularly undertaken Harmony missions across several regions.
• September 2025: The Harmony 2025 deployment began.
• November 2025: Orsi met Ding and expressed readiness for closer coordination with China.
• December 2025: China released its Policy Paper on Latin America and the Caribbean, including plans for stronger military ties.
• January 2026: US forces captured Maduro earlier in the month.
• Last Tuesday before January 26: Silk Road Ark arrived in Montevideo for a four day technical stop, barely two weeks after the US operation.

After replenishing supplies in Montevideo, the ship was expected to continue to further destinations, likely Peru and Chile before traveling to Papua New Guinea. Those next stops were described as likely, with no dates given.

Beijing Sets Out Its Military Plans for the Region

China's Policy Paper on Latin America and the Caribbean, released last December, explicitly calls for deeper military relationships. The document sets out a program of contact between senior officials, policy discussions and regular mechanisms for meetings.

The Chinese government described its intended military cooperation in the policy paper as follows:

China will actively carry out military exchanges and cooperation with [Latin America and the Caribbean] countries, expand friendly exchanges between defense and military leading officials of the two sides, strengthen policy dialogue and set up working meeting mechanisms.

The document also described the relationship between China and Latin America as:

not subjugated by any third party,

Beijing's wording directly challenges the interpretation of the Monroe Doctrine that places the hemisphere within Washington's sphere of influence. In practical terms, China is presenting its relationships with Latin American governments as decisions for those governments and Beijing, rather than arrangements subject to American approval.

Silk Road Ark's visit gives a concrete example of the military contact described in that policy. A port call brings a naval vessel into a country's harbor, while the broader policy seeks sustained exchanges between defense establishments. Together, those activities form part of China's effort to develop lasting regional relationships.

A Hospital Ship Within a Much Larger Navy

China's navy has more than 370 vessels and is the world's largest by hull count. That measurement counts ships. The hospital ship mission is one part of a broader modernization effort under President Xi Jinping to give the People's Liberation Army the ability to operate globally.

Xi has instructed the PLA to become a "world-class military" by 2049. Intermediate targets include achieving capabilities for reunification with Taiwan by 2027 and full modernization by 2035. These goals link nearer military development to a longer ambition for global reach.

Under Xi, China's military priorities have shifted from a predominantly land based focus toward operations at sea and in the air, space, cyber and electromagnetic domains. The last two involve computer networks and the signals used by military systems. The naval component seeks a "blue water" capability, meaning the ability to operate far from China's coastal waters.

Between 2014 and 2018, China launched naval vessels whose total tonnage exceeded that of the entire fleets of many major world navies combined. Tonnage measures the size of vessels, giving another view of the scale of shipbuilding alongside the count of individual ships.

Long voyages such as Harmony 2025 fit into this outward movement. They bring Chinese naval personnel and ships to distant ports while using medical diplomacy to build international relationships. The Montevideo stop connects that global naval ambition with Beijing's specific plans for Latin America.

Washington Revives Its Hemisphere Strategy

The United States has responded to China's expanding regional presence through diplomatic pressure, economic initiatives and military posturing. US officials describe the renewed focus as following years of neglect in Latin America.

The Trump administration's National Security Strategy states an intention to:

reassert and enforce the Monroe Doctrine to restore American preeminence in the Western Hemisphere.

The same strategy sets out the restrictions Washington wants to place on competitors from outside the region:

We will deny non-Hemispheric competitors the ability to position forces or other threatening capabilities, or to own or control strategically vital assets, in our Hemisphere.

The strategy connects military presence with ownership or control of important infrastructure. Washington's concerns therefore extend beyond visiting ships to assets such as ports that can matter for trade and strategic access.

The Pentagon has announced a potential sale worth $1.5 billion to upgrade facilities near China's megaport in Peru, as part of plans for military base upgrades near growing Chinese infrastructure projects in the region. Officials described the proposed sale as one that:

would not alter the regional military balance

The proposed upgrade places American security activity close to a major Chinese infrastructure project. It illustrates how competition over commercial connections and competition over military access are developing in the same places.

Technology and Naval Access Extend the Competition

US officials have also expressed concern about China's Military-Civilian Fusion strategy. The strategy integrates civilian technology with military applications, connecting developments in the commercial economy with the needs of China's armed forces.

A former US official, whose name was not given, described the strategic objective attributed to the Chinese Communist Party, or CCP, in these terms:

Chinese strategic writings make clear that the objective of the CCP's strategy is not merely to acquire power and influence for China on the world stage, but in fact to displace U.S. power and influence so as to reclaim the central geopolitical status and role of which China believes it was robbed by Western imperialism.

Competition over naval relationships also reaches Southeast Asia. USS Cincinnati recently made a friendship visit to Cambodia's Ream Naval Base, becoming the first US Navy warship to dock there since completion of a renovation funded by China.

The Philippines, meanwhile, continues to strengthen its military capabilities with new patrol vessels designed to counter China's assertive behavior in the South China Sea. These developments show the geographic breadth of the rivalry: military cooperation, infrastructure and access to ports are matters of competition in both Asia and Latin America.

Trade and Infrastructure Supply the Economic Foundation

Xi launched the Belt and Road Initiative in 2013. It has expanded from an initial focus on Asia to include Africa, Oceania and Latin America, widening China's economic and political influence through projects such as ports, railways, energy pipelines and telecommunications networks.

David Sacks, an expert on US and China relations at the Council on Foreign Relations, described the effect on international commerce:

China has had a fair amount of success in redrawing trade maps around the world, in ways that put China at the center and not the U.S. or Europe,

A total of 147 countries, accounting for two thirds of the world's population and 40 percent of global gross domestic product, have signed on to Belt and Road projects or indicated interest. Gross domestic product, or GDP, measures the value of goods and services produced in an economy.

China has spent an estimated $1 trillion on Belt and Road efforts worldwide. Estimates of spending over the initiative's lifetime reach as much as $8 trillion. The projected total is eight times the estimated spending so far, illustrating the scale of the ambitions attached to the program.

For Beijing, the initiative serves several economic purposes: building trade links, cultivating export markets, increasing Chinese incomes and finding overseas uses for excess productive capacity. That last term refers to the ability of Chinese industries to produce more than their existing markets can absorb.

The initiative also helps develop western parts of China that have historically received less attention than the eastern seaboard. Energy links from Central Asia and the Middle East support access to supplies through routes that the US military cannot easily disrupt.

Infrastructure ties can create dependence as well as commercial opportunities. Ports, transport routes and communications networks connect economies over many years, giving the relationships behind them a strategic role alongside their everyday economic function.

Latin American Governments Seek Room to Choose

The United States has tried to answer Chinese infrastructure investment with initiatives of its own. President Joe Biden and the Group of Seven launched the Build Back Better World Initiative, known as B3W, which was later renamed the Partnership for Global Infrastructure and Investment.

One year after B3W was announced, commitments totaled only $6 million. That figure illustrates the difficulty of building an alternative to China's financial resources and extended investment plans. It refers to commitments at that stage of the American backed initiative, while the $1 trillion figure describes estimated Chinese Belt and Road spending worldwide.

Latin American governments are pursuing their own interests while managing relationships with both powers. Brazil, an emerging economy and a member of the BRICS group of developing nations, maintains close ties with China and the United States.

Celso Amorim, chief adviser to Brazilian President Lula, described Brazil's approach to Washington:

We are very much interested in maintaining good relations with the United States, let that be clear,

Amorim also set out the terms Brazil seeks for that relationship:

But those relations must be based on mutual respect; they must be conducted through dialogue.

In Mexico, Ricardo Monreal, parliamentary leader for the ruling Morena party, challenged the assumption that proximity to the United States automatically determines political alignment:

The United States believes that Mexico's alignment with the American empire is automatic. I don't think it's that simple,

Uruguay's partnership with China, Brazil's insistence on dialogue and Monreal's comments reflect a shared regional concern with preserving room for national decisions. Silk Road Ark's arrival brings that concern into a visible setting: a Chinese naval vessel making its first call in Uruguay while Washington presses for renewed primacy in the hemisphere.
