The Persian Gulf has been pushed into uncharted, high-risk territory following the Trump administration’s decision to impose a naval blockade on the Strait of Hormuz, a strategic chokepoint that carries roughly one-fifth of the world’s daily oil shipments. The controversial measure was announced by former President Donald Trump after ceasefire negotiations with Iran collapsed on April 11, with the breakdown rooted in Iran’s refusal to relinquish its claimed control over the strait. Washington’s blockade is explicitly framed to counter two Iranian moves: Tehran’s plan to block passage for vessels it considers hostile, and its proposal to implement a new transit toll system for all commercial ships passing through the waterway.
Beyond its stated goal of countering Iran, the blockade marks a deliberate show of force by the Trump administration that directly challenges Beijing. In recent years, China has emerged as the largest buyer of Iranian crude oil, and it is one of the only countries whose commercial shipping has been able to transit the strait without interference from regional forces. This special status was put to an early test on April 14, when the Rich Starry, a Chinese-owned and operated tanker already under US sanctions for carrying Iranian oil, prepared to make the passage. While many observers expected a direct confrontation between the tanker and US naval forces deployed to the region, the vessel ultimately reversed course in the Gulf of Oman and turned back. US officials have since confirmed that six vessels attempting to transit the strait have been turned away under the blockade.
The Rich Starry’s decision to avoid confrontation has been widely interpreted as a signal that Beijing is not yet willing to directly challenge Washington’s stated red lines in the region, particularly ahead of a planned US presidential state visit to China scheduled for next month — a trip that was originally postponed from March 31 amid escalating tensions with Iran. Beijing has already publicly condemned the US blockade, labeling it a “dangerous and irresponsible act” that threatens global energy security. Even so, the decision to step back from a direct clash may be read by Washington as a sign of Chinese reluctance to escalate, a perception that analysts warn could embolden the Trump administration to take more aggressive action against Chinese shipping in the region going forward.
Any attempt by the US to seize a Chinese-flagged or Chinese-owned tanker carries severe escalation risks. If Washington moves to seize a vessel, Beijing could easily characterize the action as an act of war, framing it as a deliberate attempt to disrupt the Chinese economy by cutting off critical energy supplies. While a direct armed confrontation between the United States and China in the Persian Gulf remains unlikely at this stage, the crisis has already spurred speculation that Beijing could deploy its 48th Escort Group, based at its military facility in Djibouti, to the region. The unit has long conducted anti-piracy patrols and escort missions for Chinese commercial ships in the Gulf, and its deployment would raise a pressing new question: would Washington be willing to open fire on Chinese naval vessels to enforce its blockade?
Beyond direct naval confrontation, China has multiple indirect options to respond to the US move. One widely discussed path is increased military support for Iran. Unconfirmed intelligence reporting from The New York Times has alleged that Beijing has already shipped shoulder-launched anti-aircraft missiles to Tehran, a claim that Chinese officials have repeatedly and forcefully denied. China’s Beidou satellite navigation system is already known to provide positioning support for Iran’s existing missile arsenal, which is targeted at US and Israeli assets in the region. Additional transfers of advanced weapons, including long-range missiles and attack drones, would allow Beijing to counter the US blockade without direct engagement.
Alternative, Beijing could choose to retaliate against US interests outside the Middle East, targeting American economic and strategic assets in the Asia-Pacific. The current context plays into this possibility: the US has already redeployed key missile defense systems from South Korea to the Middle East, leaving American allies in the Asia-Pacific more exposed. At the same time, fuel shortages sparked by strait disruptions have already put additional economic strain on regional powers, creating more openings for Chinese action if Beijing chooses to escalate.
Despite Beijing’s stated preference for a stable Middle East and open global trade — a status quo from which China has benefited enormously from decades of globalization — the crisis also creates unique strategic and economic opportunities for China to advance its long-term goals. One of the most significant is the expansion of the renminbi’s role in global energy markets. Iran already conducts nearly all of its oil trade transactions in renminbi, accelerating the rise of the so-called petroyuan as a challenger to the decades-long dominance of the petrodollar in global energy trade. Combined with China’s position as the leading supplier of aviation fuel across the Asia-Pacific, the current crisis has already cemented China’s larger role in the global energy economy.
Another potential beneficiary of prolonged energy market disruption is China’s electric vehicle (EV) industry. A sustained oil shortage would likely push more consumers and governments to accelerate the transition to EVs, a market where Chinese manufacturers like BYD already hold a dominant global market share. Analysts draw a parallel to the 1970s OPEC oil crisis, when fuel-efficient Japanese vehicles outcompeted larger, less efficient American and European models, capturing massive global market share. A prolonged oil crisis today could similarly turn Chinese EV brands into global household names, expanding the global influence of “Brand China.”
Finally, the crisis reinforces China’s ongoing narrative that it is a more reliable and stable global partner than the United States, amid widespread perceptions of unpredictability from the Trump administration over the past 15 months. China already holds a more favorable global public image than the US in most international polling, and a wider regional conflict stemming from the blockade would likely widen that gap further. In the end, the course taken by the Rich Starry may end up charting the future trajectory of US-China great power competition, and the shape of the global order that competition will produce.
