On September 8, the US Treasury proscribed 36 aviation-related entities, including 27 Iranian airlines and a network of foreign ticketing agents, ground-service providers, and aircraft-procurement companies. The list includes much of Iran’s remaining commercial aviation sector—Iran Air, Iran Aseman, Kish Air, Qeshm Air, Saha Airlines—alongside Mahan Air, which was already under US sanctions.
The US is casting the move as part of Operation Economic Outcast. However, it is better understood within the framework of Washington’s wider, multi-theatre war to preserve US financial supremacy—and as such Beijing is the real strategic target.
Treasury Secretary Scott Bessent made the intention unmistakable on September 21: “On September 23, all Iranian airlines will be shut down globally.” The threat was brutally explicit: any foreign entity that fuels Iranian aircraft, lands them, or sells tickets for them will be cut off from the dollar system. The blacklisting of Iranian airlines is merely a vehicle for the real weapon: the secondary sanctions against every third party that does business with Iran. This is intended to manufacture a direct confrontation with China.
Beijing’s Dilemma: Compromise Means Surrender, Defiance Means Pretext
China now faces a carefully engineered dilemma meticulously timed to coincide with Xi Jinping’s state visit to the US
If Beijing acquiesces to the pressure from the United States—even quietly, by allowing major banks, state-owned aviation enterprises or large insurers to withdraw from Iranian route services entirely—the cost to China’s credibility will be huge. It will be viewed both internationally and domestically as conceding ground on areas of economic sovereignty, a point Washington understands only too well.
As recently as May, China’s Ministry of Commerce invoked its 2021 Blocking Rules for the first time, formally prohibiting Chinese organizations and individuals from recognizing, implementing or complying with US sanctions against five Chinese refineries accused of purchasing Iranian oil. The move was much more than a technical legal manoeuvre. It was a principled rejection of the US doctrine of universal jurisdiction and of unilateral sanctions—a public declaration of where the bottom line on economic sovereignty lies. If, just months later, China quietly concedes in the aviation sector, that order becomes a dead letter—and Beijing’s entire economic sovereignty narrative is severely undermined.
If Beijing refuses—continuing to accept Iranian flights and maintains connectivity through selected carriers and companies with limited exposure, which looks like the chosen course—Washington will use this as a pretext for escalation. Bessent has already said the US “knows who the enablers are” and is “stopping them.” He specifically mentioned “behind-the-scenes discussions” with People’s Bank of China Governor Pan Gongsheng, describing China as “very much involved in this process.” Bessent is explaining how this situation is being used to exert leverage over Beijing.
This is the impossible position: agree, and lose credibility by conceding sovereignty; refuse, and provide the political justification for escalation. Both roads lead to the same destination—Washington constructs a point of conflict through which it can escalate economic pressure in whichever direction. It can use weakness to force greater concessions, or strength as a pretext to increase economic pressure.
Calibrated Defiance: China Keeps the Flights Flying
So far, China has openly challenged Washington’s ultimatum. Although the September 23 sanctions deadline prompted cancellations across several US-aligned or financially exposed jurisdictions, Mahan Air flights have continued operating to Guangzhou and other Chinese destinations. Chinese airports are still providing the landing, handling and refuelling services needed to keep those flights in the air.
As yet, Beijing has not issued an aviation-specific blocking order as it did following the US sanctions against five Chinese refiners accused by the US of dealing with Iran. But its behaviour is starting to form a pattern: a policy of calibrated defiance. China has rejected Washington’s authority to dictate relations with Tehran and has preserved essential transport links, but at the same time is limiting the exposure of its largest banks and internationally connected companies. The immediate US claim that Iranian airlines would be grounded worldwide has therefore failed. The longer-term test will be whether China can sustain these routes against mounting pressure.
Beijing’s stance of calibrated defiance is symbolically extremely important but it also shows why these secondary sanctions are so dangerous. They force Beijing to expose the limits of its tolerance for risk. It shows that Beijing is willing to absorb some risk, but not unlimited risk. And every route it keeps open, every airport that continues servicing Iranian carriers, every financial institution that quietly facilitates the arrangement, reveals a data point about where China’s red lines actually are. And Bessent is taking notes.
The Real Target of Aviation Sanctions: Pre-Positioning Leverage for a Financial Showdown
Why is the United States expanding sanctions from oil to aviation now? Why has air transport become the newest front in Operation Economic Outcast?
The answer lies in the manufacture of leverage. Iran’s oil exports have been covered by sanctions for years. China continues to purchase Iranian crude through renminbi settlement, independent refineries and a “shadow fleet”—a channel that is now relatively mature. But aviation is different. Aviation services—fuel, landing, maintenance, insurance, ticketing—are deeply dependent on international financial infrastructure. The clearing systems of the International Air Transport Association, dollar-denominated aircraft leasing, and the reinsurance networks of aviation insurance are heavily embedded in the Western-dominated financial architecture. By threatening secondary sanctions against service providers, Washington is effectively testing: how much is China willing to pay for Iran’s aviation connectivity, and, by extension, how much China’s middle-class travellers are willing to pay. Which institutions, which channels, which companies will Beijing deem expendable, and which are vital?
This testing process is itself part of the manufacture of leverage. Every time China chooses who to protect and who to sacrifice, it reveals the boundaries of its risk tolerance. And that information is priceless in the larger financial confrontation that is coming. It is also designed to put China off-balance. The timing of Bessent’s announcement—immediately prior to Xi Jinping’s state visit—is by no means coincidental.
This is the core logic of the Petroyuan Trap: the US war against Iran, and the accompanying “permanent disruption” of the Strait of Hormuz, are fundamentally about manufacturing the conditions for economic containment of China. The closure of Hormuz is not an accident—it is a planned outcome. Bessent himself has acknowledged the strait “will never go back to the way it was.” This means global energy prices will be structurally driven higher and China—as the world’s largest energy importer—will face a simultaneous squeeze from soaring import costs and shrinking export demand.
Within this framework, the aviation sanctions are a tactical node. Their function is—before the economic shock fully materializes and before the financial confrontation begins to escalate seriously—to create an economic punishment lever that US can escalate and de-escalate at will.
The Broader Architecture: Economic Chemotherapy and the Weaponization of Finance
The Trap posits that the US war against Iran and the subsequent disruption to the Strait of Hormuz are designed to shape the economic landscape for an economic and financial trap. This is a trap intended to manufacture the leverage necessary to economically contain China, fracture BRICS, and consolidate financial hegemony over the Global South through a form of Economic Chemotherapy and weaponization of the global financial architecture.
The aviation sanctions fit this architecture perfectly. They are not designed to achieve a definitive outcome—Iran’s airlines will not disappear simply because they are blacklisted. They are designed to create a permanent, escalatory pressure point. A point at which China must repeatedly balance credibility and risk. A point at which every choice reveals more about Beijing’s limits and vulnerabilities. A point at which the United States can calibrate its next move based on what it learns.
The ultimate target is not Iran’s aviation sector. The ultimate target is the financial architecture that China is trying to build as an alternative to the dollar system—the renminbi settlement channels, the BRICS payment mechanisms, the protected economic corridors that allow trade to continue outside Western control. Every one of these is a threat to dollar hegemony. And every one of them depends, at least in part, on the willingness of Chinese institutions to absorb risk.
The aviation sanctions are an economic punishment lever but they are also a stress test. They are designed to determine how much risk China will absorb—and to weaken the alternative architecture before it can fully mature either through Beijing’s retreat or Washington’s force.
Conclusion: A Game of Who Blinks First
US sanctions on Iranian aviation are of far greater strategic significance than mere economic impact. They do not expect to completely sever Iran’s international aviation links—as long as China continues to accept Iranian flights, that goal cannot be achieved. Their real function is to create a sustained, escalatory pressure point that forces China to repeatedly weigh credibility against risk, and each time it makes this calculation it exposes its bottom line and its vulnerabilities.
Beijing has already demonstrated its response pattern: publicly reject the legitimacy of sanctions while quietly protecting core financial institutions from direct exposure. This is a carefully calibrated strategy of semi-confrontation. It maintains a minimum level of Iranian connectivity while avoiding a frontal assault from the dollar system.
The question is therefore: How long can China keep walking this thin line? How long can China sustain this degree of ambiguity? Most likely, it is until the energy shock generated in the Strait of Hormuz arrives in full force and the threat of secondary sanctions and tariffs expands from aviation to the entire trade domain. At that point the space for ambiguity will have ceased to exist—possibly long before then.
The Iran war is aimed, ultimately, at China. The aviation sanctions are the bridgehead that allows the war to move from a kinetic domain in the Strait of Hormuz to a financial domain in Shanghai. The door of the trap is closing. The question is not whether Beijing can see it—it can. The question is whether, when the Trap closes, it will have constructed the economic, financial, and political space it needs to slip through.
