Panama decided that China had gained too much influence over one of the most strategically important waterways in the world.

China’s response appears to have been to punish Panama for doing something about it.

Since Panama’s Supreme Court removed a Hong Kong company from control of two critical ports at opposite ends of the Panama Canal, Beijing has unleashed a series of economic pressures against the small Central American country.

Panamanian ships have been detained in Chinese ports. Chinese companies have been told to reconsider investments. Panamanian exports have faced additional inspections. China’s giant state-owned shipping company COSCO stopped using a major Panamanian port. Beijing has even summoned international shipping companies hired to replace the former port operator.

China denies that it is retaliating. The pattern suggests otherwise.

“China’s response was swift and punishing,” Warren Stephens, the U.S. representative to the International Maritime Organization, said.

The confrontation also raises a larger question about China’s economic relationships around the world. If a country makes a sovereign decision that Beijing dislikes, what happens next?

Panama is finding out.

How China Lost the Ports

The dispute centers on Balboa and Cristóbal, container terminals positioned at opposite ends of the Panama Canal. Balboa sits on the Pacific side. Cristóbal is on the Atlantic side. That makes the two ports extraordinarily important pieces of infrastructure surrounding a canal carrying roughly 5 percent of global maritime trade.

Panama Ports Company, a subsidiary of Hong Kong-based CK Hutchison, had operated the terminals since the 1990s. The original 25-year concessions were granted in 1997 and renewed in 2021 for another 25 years. But the arrangement increasingly came under scrutiny.

A lawsuit challenged the legality of the concessions, while an audit reportedly discovered accounting problems and other irregularities. Those problems reportedly cost Panama about $300 million since the concession was extended and an estimated $1.2 billion over the original 25-year agreement.

Then came the constitutional issue.

In January, Panama’s Supreme Court ruled that the laws and agreements supporting the concessions violated Panama’s constitution. Among the problems cited were exclusive privileges and tax exemptions granted to the company. The government subsequently canceled the concessions and took control of the ports.

CK Hutchison has rejected the allegations and is seeking more than $2 billion in damages through international arbitration.

China was furious.

Beijing warned that Panama could pay a “heavy price.” Then the pressure began.

1. Panamanian Ships Suddenly Face Detention

Perhaps the most striking action has involved ships flying Panama’s flag.

Panama operates one of the world’s largest ship registries, with approximately 8,500 vessels sailing under its flag. Registration fees make the industry economically important to the country.

After the court ruling, inspections and detentions of Panamanian vessels in China soared.

Nearly 70 Panamanian-flagged vessels were reportedly detained in March alone. By May, 146 vessels were detained that month. Asia-Pacific inspection data cited by The Wall Street Journal showed nearly 500 Panamanian-flagged ships detained for safety reasons in Chinese ports since January.

Panamanian Foreign Minister Javier Martínez-Acha directly connected the increase to the court decision.

“As a result of the ruling, our commercial shipping fleet, the most important in the world, has seen an increase in inspections and detentions of vessels flying our flag in ports of the People’s Republic of China,” he said.

Some shipowners have reportedly responded by abandoning the Panamanian registry.

2. Ships Can Be Held for Weeks

The inspections are not necessarily minor inconveniences.

Seafarers and a ship manager told The Wall Street Journal that once vessels enter Chinese ports, inspectors board them and identify alleged safety problems. The ship can then be ordered to anchor while the problems are corrected.

Some vessels have reportedly remained detained for more than a month.

China insists its inspections are legitimate and says Panamanian vessels have been involved in a disproportionate number of accidents, deaths and missing-person cases.

But American officials have described the surge differently.

U.S. Federal Maritime Commission head Laura DiBella said the intensified inspections appeared “intended to punish Panama after the transfer of Hutchison’s port assets.”

3. China Targets Panama’s Bananas and Coffee

The pressure has extended beyond ships.

Chinese customs authorities reportedly increased inspections of Panamanian products, including bananas and coffee.

Agricultural exports represent only a fraction of Panama’s total exports to China, limiting Beijing’s leverage. But the message is difficult to miss. When a political dispute emerged over the canal ports, ordinary commercial products suddenly became another potential pressure point.

That is precisely what makes economic dependence on China dangerous for smaller countries.

Trade can become leverage.

4. Beijing Freezes New Investments

China has also reportedly instructed state-owned companies to halt discussions involving new projects in Panama.

Potential investments worth billions of dollars could be affected.

China already has significant infrastructure involvement in Panama, including a $1.4 billion fourth bridge across the canal. Chinese companies have also participated in construction of a cruise terminal and part of a metro line.

Projects already underway could potentially be affected as well.

The message is straightforward: challenge Chinese interests and Chinese investment can disappear.

5. COSCO Walks Away From Balboa

China’s state-owned COSCO Shipping Lines then delivered another blow.

COSCO suspended operations at Balboa, the former Hutchison terminal on the Pacific entrance to the canal.

The company told customers there would be no additional incoming or outgoing traffic through its Balboa operation. Bookings were canceled and empty containers were directed toward other terminals.

COSCO did not publicly connect the decision to Beijing.

But the timing was remarkable.

The suspension came just 15 days after Panama removed Panama Ports Company.

Henry Ziemer of the Center for Strategic and International Studies said there was no definitive proof Beijing ordered the action, but added that “the circumstantial evidence overwhelmingly points to a state hand.”

6. China Pressures Hutchison’s Replacements

Panama appointed subsidiaries of two of the world’s largest shipping companies to temporarily operate the terminals.

APM Terminals, part of A.P. Moller-Maersk, took over Balboa. Terminal Investment Ltd., connected to Mediterranean Shipping Company, took over Cristóbal.

China’s Transport Ministry summoned representatives of Maersk and MSC for discussions.

The reported message was essentially a warning not to harm the interests of Chinese companies.

That means China’s pressure campaign was no longer directed only at Panama.

Companies willing to help Panama operate the ports were apparently being put on notice as well.

7. China Encourages Ships to Go Somewhere Else

Beijing has reportedly asked shipping companies to consider routing cargo through other ports when doing so would not impose significant additional costs.

That strikes directly at Panama’s ambition to become an even larger global logistics hub.

The Panama Canal is the country’s greatest strategic and economic asset. Canal revenue represented more than 7 percent of Panama’s GDP in 2025, while dividends from canal operations reportedly generated more than 20 percent of government revenue during the previous fiscal year.

Driving business away from Panama therefore strikes near the heart of its economy.

Panama Had Already Started Pulling Away

The port confrontation did not occur in isolation. Panama withdrew from China’s Belt and Road Initiative in 2025.

The country had joined the massive Chinese infrastructure program as Beijing expanded its economic presence throughout Latin America.

But Washington had become increasingly concerned that Chinese commercial investments were giving Beijing influence over strategically important infrastructure in the Western Hemisphere.

President Donald Trump made the Panama Canal one of the earliest foreign-policy issues of his second administration. He argued that China was effectively gaining control around the canal and demanded that Chinese influence be reduced.

Panama and China rejected Trump’s characterization, but Panama nevertheless began pulling away from Beijing. Leaving Belt and Road was one step. Removing CK Hutchison from Balboa and Cristóbal was a much bigger one.

The Strategic Problem Was Impossible to Ignore

Whether CK Hutchison should technically be described as “China” is less important than the strategic reality Panama and Washington were confronting.

A Hong Kong company had control of major container terminals located at both ends of the Panama Canal. The United States is the canal’s largest user. China is the second largest.

The canal connects the Atlantic and Pacific oceans and carries a substantial portion of world maritime commerce. Allowing a company vulnerable to Beijing’s influence to occupy such strategic positions was therefore never simply an ordinary commercial arrangement from Washington’s perspective.

Ironically, China’s reaction may be strengthening that argument.

Ziemer noted that Beijing’s response appears to suggest that Hutchison’s position was regarded as a Chinese strategic asset rather than simply a private commercial investment. If the ports were merely a business investment by an independent Hong Kong company, why would China’s government threaten Panama with a “heavy price” after the company lost its concessions?

Why would Chinese state-owned companies reconsider investments?

Why would Panamanian ships suddenly face extraordinary scrutiny?

Why would China’s state-owned shipping giant abandon Balboa?

And why would Beijing summon the international companies replacing Hutchison?

Those are uncomfortable questions for China.

What Comes Around Goes Around

There is considerable debate over how much credit Trump deserves for what happened.

Panama’s Supreme Court made the decision, and the ruling was based on Panamanian constitutional law. The case involved allegations and irregularities that existed independently of Trump. It would therefore be difficult to claim that Trump simply ordered China out of the canal and Panama complied.

But there is little doubt that Trump put enormous public pressure on Panama over Chinese influence, and he is probably enjoying what happened next.

China lost control of two extraordinarily strategic port facilities. Panama pulled away from Belt and Road. Beijing’s influence around the canal has been weakened.

China then responded in a way that may demonstrate exactly why Panama had reason to worry about becoming too dependent on Beijing in the first place.

A large country does not demonstrate that it is a trustworthy economic partner by threatening a much smaller country for exercising its sovereignty.

It does not prove its peaceful intentions by disrupting ships, threatening investment, pressuring exporters and intimidating companies that step in after it loses a commercial dispute.

Panama is now getting an unusually clear demonstration of what Chinese bullying looks like.

And in trying to punish Panama for escaping its economic grip, Beijing may ultimately provide other countries with one more reason to make sure they never fall too deeply into that grip themselves.
