April 25, 2026: Desert Storm made the modern Chinese military. What is the Iran War doing to it? In January 1991, Chinese military officers watched CNN recordings of the United States dismantling the Iraqi Army and experienced what one Chinese military analyst later called a disturbing nuclear attack. Desert Storm displayed every capability the Chinese military lacked, and China had no choice but to begin remaking its military from the ground up.

Two years later, China’s Central Military Commission codified these lessons in the Military Strategic Guidelines centered on Local Wars Under High Technology Conditions and acknowledged the Chinese military had been preparing for the wrong war. The Gulf War didn’t just scare China; it gave it direction.

Thirty-five years later, the classroom has reopened. The United States and Israel are engaged in a military campaign against Iran, and the Persian Gulf is once again the center of a maritime crisis. The Strait of Hormuz is temporarily closed. Not by minefields or naval blockade, but by the withdrawal of maritime insurance and the cascading commercial decisions that followed.

Tanker traffic dropped first by approximately 70 percent with almost 150 vessels loitering outside the Strait. Transit has since collapsed to nearly zero within the first week, disrupting roughly 20 percent of the world’s daily oil supply and significant volumes of liquefied natural gas. Roughly 750 vessels were stranded inside the Persian Gulf, and the Chinese military paid very close attention.

Immediate intuition is to assume that China is enjoying the turmoil: a distracted America, its military tied down in the Middle East, and precision munitions being expended far from the Pacific. That instinct is wrong.

What the Chinese military's most attentive analysts are likely doing is war-gaming a Taiwan scenario in real-time using the Hormuz crisis as a live stress test for assumptions they have been modeling for decades. Some of what they are finding is profoundly uncomfortable. The tactical lessons are significant but broadly familiar. However, the deeper strategic lessons, the ones that will reshape Chinese planning for the Taiwan Strait and South China Sea, are maritime.

In 1991, China’s Desert Storm lesson was almost entirely about its capability gap. The maritime domain barely registered because the Gulf War was largely a land-air campaign. The 2026 crisis is fundamentally a maritime crisis, and China is learning a new lesson: chokepoints do not just threaten an enemy, they threaten anyone who depends on them.

Approximately 84 percent of the oil transiting through the Strait of Hormuz flows to Asian markets. China alone imported roughly five million barrels per day through the Strait, representing approximately 40 to 45 percent of its total crude imports. The Hormuz closure does not primarily threaten Houston or Rotterdam. It throttles the Chinese ports of Tianjin, Qingdao, and Zhoushan.

Prolific naval strategist Alfred Thayer Mahan understood this. He spent much of his groundbreaking work, The Influence of Sea Power Upon History, explaining not just how navies project power but how dependence on sea lines of communication creates strategic vulnerabilities. A nation that does not control its own supply lines does not truly control its own strategic fate.

The Chinese military absorbed this lesson from Mahan and filtered it through the lens of Desert Storm’s demonstration of American power projection. In response, China has been building a blue-water navy and acquiring global port access in response.

However, the Hormuz crisis is forcing China to confront a gap that was not illuminated by Desert Storm nor discussed in any specificity by Mahan: China remains critically dependent on chokepoints it cannot protect and does not control. The Strait of Hormuz is the immediate problem, but the Strait of Malacca, through which 80 percent of China’s oil imports transit, is the permanent one.

China’s Foreign Ministry has been reduced to urging all parties to keep the shipping routes in the Strait of Hormuz safe, and reports that China has opened direct talks with Iran to negotiate safe passage for energy shipments underscores that vulnerability. A nation that must ask permission to use a chokepoint does not command it. For Chinese military planners war-gaming a Taiwan contingency, the lesson is immediate: any conflict that triggers a disruption at the Malacca Strait could strangle China’s economy before a single shot is fired. In that regard, Indonesia and the United States have recently made an agreement for their military forces to be interoperable, which has been critical for NATO’s military efficiency. The Indonesian Navy also sinks intruding Chinese fishing vessels outright rather than taking them into port. Indonesia controls the entire eastern coast of the Malacca Strait.

If the choke point lesson is uncomfortable, the insurance lesson may be worse. Within 72 hours of the start of Operation Epic Fury, multiple members of the International Group of Protection and Indemnity Clubs, which collectively insure roughly 90 percent of the world’s ocean-going tonnage, issued formal cancellation notices for war-risk coverage in the Gulf. Major container lines suspended operations. Lloyd’s Market Association confirmed that roughly 1,000 vessels with a hull value of over $25 billion sat anchored in the area. The choke point was not closed by missiles. It was closed by spreadsheets.

The Chinese military is likely studying this closely because it maps directly onto a Taiwan scenario. Beijing has long assumed that the critical question in a cross-strait contingency would be whether the Chinese navy could establish sea control. The Hormuz crisis suggests a different question entirely: would commercial shipping continue to flow through the Strait of Malacca and South China Sea once insurers withdraw coverage and container lines suspend service?

The same insurance mechanism that shut Hormuz in 72 hours could shut the commercial sea lanes on which China’s economy depends. Unlike a naval blockade, an insurance withdrawal cannot be stopped by force. No navy can compel an underwriter to write a policy.

China has been building state-backed maritime insurance mechanisms and positioning its commercial fleet to operate under sovereign-risk coverage precisely to insulate itself from the kind of Western-backed market dependency that has strangled Gulf shipping. The Hormuz crisis validates that investment.

On the other hand, it also reveals how far Beijing needs to go. China’s maritime insurance ecosystem does not yet have enough depth or international credibility to underwrite the scale of coverage that a Taiwan-related disruption would demand. A harder problem still is even if China can ensure its own flag vessels, it cannot compel foreign-flagged ships to continue sailing into a warzone.

The roughly 750 vessels stranded in the Persian Gulf were a preview of what the South China Sea could look like 48 hours into the Taiwan crisis. Commercial shipping was frozen, supply chains severed, and the Chinese navy unable to restart them regardless of how many ships it deploys.

The Hormuz crisis is also teaching China a lesson about commercial shipping as a military instrument. When the United States declared a maritime warning zone in the Persian Gulf, it came with an unusual public admission: it could not guarantee the safety of merchant shipping. The major container lines made their own risk calculations and suspended operations. The financial architecture of global trade enforced a blockade more completely than any naval minefield.

Sinokor, a South Korean shipping conglomerate, began asking the equivalent of roughly $20 per barrel to transport oil to China. This was an extraordinary premium compared to the nominal $2.50 per barrel, and this illustrates how quickly commercial sealift becomes a strategic weapon when maritime risk spikes.

China has been preparing for exactly this scenario. Over the past two decades, Beijing has expanded its merchant fleet to over 4,000 internationally trading ships, captured over 46 percent of global commercial shipbuilding, and invested in the mariner training pipeline to crew those vessels. Critically, the Chinese military has also been integrating commercial shipping into military logistics planning. China’s national defense mobilization laws allow the requisitioning of civilian vessels, and its merchant fleet has been designed with dual-use capability in mind.

The Hormuz crisis is validating China’s investment in a state-linked merchant marine fleet while simultaneously demonstrating the cost of America’s failure to maintain one. However, it is also exposing a gap in China’s own planning: a fleet that can be mobilized for war is also a fleet that can be commercially paralyzed by insurance withdrawal, sanctioned by coalition financial instruments, or stranded at foreign ports. In a Taiwan contingency, the Chinese military’s ability to move troops across the Strait may matter less than whether China’s commercial fleet can continue to feed, fuel, and supply the mainland economy under wartime conditions. The Hormuz crisis is the first live demonstration of how quick commercial architecture can collapse.

Desert Storm inspired China to spend 35 years building the military it now has. Operation Epic Fury will not trigger the same kind of wholesale structural overhaul – the Chinese military has already done that work. What the 2026 crisis is doing is stress-testing China’s maritime strategy against live data and finding specific, uncomfortable gaps: chokepoint dependency that blue-water naval investment has not yet solved, an insurance architecture that can impose a blockade no navy can break, and a commercial fleet that can be mobilized for war but paralyzed by the financial instruments.

Each lesson applies directly to the Taiwan Strait and South China Sea. Chinese military planners are not watching the Hormuz crisis as a distant curiosity. They are watching it as a dress rehearsal, and they are taking notes on themselves as much as on the United States.

Mahan argued that sea power rests on two pillars: naval force and commercial maritime enterprise. China has been absorbing both halves of that doctrine. The Strait of Hormuz crisis is revealing that even both halves may not be enough. The question is whether the United States, which builds less than one percent of the world’s commercial ships, fields fewer than 80 vessels in international trade, cannot crew the sealift fleet it already has, and had no war risk insurance mechanism ready when the crisis broke, is learning it too.
