A large wooden barge, named MSV Haji Ali, was rocked by a huge explosion somewhere off the coast of Oman on Wednesday evening. The 175-foot-long Indian-flagged cargo ship carrying livestock to the UAE from Somalia's port of Berbera was lost within hours. The Omani Coast Guard rescued all 14 crew members but the ship sunk with its cargo, probably carrying the animals. Officials in India and Oman refused to immediately identify the attacker. Nobody needed to.

Haji Ali is not the first ship which has been lost in the waters since February 28. It will by no means be the last. Its sinking, on the day Trump met Xi in the Great Hall of the People in Beijing to discuss the reopening of the Strait of Hormuz, encapsulates something fundamental about the world in which we live: the disconnect between what diplomats say in gilded rooms and what's happening on the water.

How a blockade came together, and how it came apart.

Since 28 February 2026, Iran's shipping traffic through the Strait of Hormuz has been largely disrupted following the air operations conducted by the United States and Israel and threats from the IRGC to close the strait to all vessels, including boardings and attacks on merchant vessels and the deployment of sea mines in the main shipping lanes. The magnitude of the numbers makes this the most significant disruption in modern maritime history. Prior to the war, some 20 million bpd of oil passed through the strait, accounting for around 20% of world oil shipping movements and 20% of world LNG shipping movements. The Persian Gulf region also generates almost 30-35% of world's urea export — a fertilizer used to crop cultivation from South Asia to West Africa.

Iran has used four layers of strategy to keep the strait closed, including making navigation difficult with satellite spoofing and GPS jamming, and using sea mines as a hidden and long-term threat, but most importantly, physical assault by boats, drones and missiles. The mix has proven to be extremely effective. The volume of commercial traffic fell by over 90% compared with pre-war levels. The cost of insurance for ships trying to pass through the strait went up four to six times higher than before, and even when Iran wasn't actually shooting at ships, it was not financially feasible for most shipowners to make the attempt.

Trump's stated intention was to be in Beijing when Iran has capitulated, with Iran's nuclear stockpile handed over, the Strait reopened and the mullahs humbled. All of this didn't occur. The Iran war was inconclusive, and the Strait was largely controlled by Iran. As Air Force One was parked on a Beijing tarmac, the sinking of the MSV Haji Ali came, almost on cue.

The selective passage game — and what it reveals is that the words chosen for it are very specific.

Maybe the most significant move in the Hormuz crisis is what Iran has not blocked. The Islamic Republic started accepting some Chinese ships to pass through the Strait with an understanding about Iranian management mechanisms in the waterway, Iranian state media reported, as Trump and Xi held talks in Beijing. It was almost certainly a carefully-timed message from Tehran. China gets through. America's allies don't.

Iran's Revolutionary Guards have exempted about 30 ships, including a couple of Indian and several Chinese ships from passing through the Strait following a request by the Chinese Ambassador to Iran and the Chinese Foreign Minister, citing the current China-Iran Strategic Partnership as the reason for the exemption. Despite the diplomatic wrangling, India managed to get two tankers carrying LPG through, a small consolation to a nation which imports approximately 90% of its oil and relies on the Strait for around half of its normal crude imports.

The selective passage is the most efficient geopolitical mechanism of Iran. The effect of Tehran's approach is that by granting access on the basis of diplomatic alignment, and not necessarily on commercial need, Tehran has effectively created a loyalty test – a way of helping the world to categorize itself into those who are willing to stand with the “US-led order,” and those willing to deal with Iran directly. Beijing is given preferential access. The MSV Haji Ali is the ally of Washington.

Under diplomatic agreements with Iran, some vessels from China, Iraq and Pakistan have been transiting through. Tehran has also been charging a toll on ships that want to pay for its control of the strait, even if any conflict is resolved, a condition it has never imposed prior to February 2026. This is not a stopgap for the war. Iran has made a concerted effort to put in place its grip on the most important energy choke point.

Rubio's Taiwan warning and the Indo-Pacific dimension.

The Strait was all over the news, but another strategic drama was unfolding in Beijing over Taiwan. Secretary of State Marco Rubio emphatically reiterated that “US policy toward Taiwan is unchanged” after Xi's summit threat and that “it would be a terrible mistake” if China tried to take Taiwan by force. Taiwan was mentioned in the discussions, as it always is, but he said both sides voiced their views and went on.

It's the asymmetry that analysts noted that's the big deal here, not the substance. “There appears to be a seriousness in Xi's statements that Trump and his team have not demonstrated so far," said one security researcher. “That disconnect between the two will impact perceptions in Taipei, throughout the Indo Pacific and beyond: Xi's comfort in raising the Taiwan question directly with Trump is an indicator of how ready the United States side was for Beijing's hardball approach.

In recent years, China's military has exercised itself for a blockade, with warships forming up in what the US Indo Pacific commanders have called "blockade rehearsals," both looking to establish a quarantine of the island and a siege. Taiwan's own spokesperson was reacting to Xi's warning, saying the military stance of China is "the only source of insecurity in the Taiwan Strait and the wider Indo Pacific region. That talk in Beijing was on trade, not an end to PLA exercises, around Taiwan. At least, the U.S. being spread thin in the Middle East has changed the strategic outlook for all the actors in the Indo-Pacific.

The Trump administration has approved an $11 billion arms package for Taiwan, but has yet to begin fulfilling it. The delay between approval and delivery is a message in itself – and Beijing knows how to read one.

India's strategic tightrope

India's role in all this should be looked at in greater detail than is the case. Through diplomatic dialogue with Tehran, New Delhi has won some passage rights through the Strait, a tacit recognition of the economic value of maintaining a back channel to Iran even while the United States is waging war against it. Meanwhile, Modi also started a five-country visit to boost energy security, inking oil and gas deals with the UAE and strategic defence cooperation deals. The UAE, meanwhile, said it was speeding up work on a pipeline that will ultimately be able to operate fully without passing through the Strait of Hormuz – which is scheduled to be in use in 2027.

India is also being provided with Iranian oil concessions, strengthening ties with UAE (which is behind the scenes behind the strikes against Iran), managing its energy exposure, and hosting a foreign ministers meeting of the BRICS bloc where Iran's own Foreign Minister Abbas Araghchi was in attendance. It's an extraordinarily complex balancing act and it's indicative of where India placed itself — in between the Iran-China-Russia axis and the US-led order, while always putting Indian interests first.

That's a risky stance, especially given the ongoing Strait crisis. Iran's foreign minister, in a confrontational statement on Indian soil, publicly accused the UAE of participating in military operations against Iran at the very BRICS meeting hosted by India.

The Obama framing and the domestic US politics angle are clearly interwoven.

There is another aspect of this crisis that is unfolding in American domestic politics, and which underpins everything else. In a candid moment on Fox News, Rubio admitted that every president over the last two decades had been concerned about the Iranian nuclear programme, which Obama made a nuclear deal with because of, and which Trump scrapped and Biden attempted to re-enter. The current government faced something qualitatively different, Rubio claimed, in that Iran was developing such a superior conventional missile and drone capability that it could easily overwhelm the defense of six Gulf nations at once and behind which a nuclear weapon, in theory, could be developed without consequence. The Iran war, according to this reading, was not reckless escalation, but a strategic necessity that was kicked down the road by previous administrations.

On that basis alone, that argument has merit. What it does not really discuss is the execution problem – that the war has gone well beyond the four to six weeks that the administration had privately envisioned, the Strait hasn't been liberated from Iranian control, and Trump has not arrived in Peking with the leverage he thought he would have. Despite the shortcomings of the Obama-era nuclear deal, it helped maintain the Strait's openness. Its lack and the military campaign that brought only a partial success led to the formation of the MSV Haji Ali.

The world is watching Iran get away with.

But there is a larger question that is quietly nursed by maritime strategists, energy traders and governments from Tokyo to Nairobi in this crisis. What does this say about the enforcement of freedom of navigation as a principle if Iran can sink an Indian cargo ship in international waters, seize a ship anchored off Fujairah, grant Chinese ships favored passage and charge tolls to other ships while the world's most powerful military is active in the same waters?

Rubio said as much: "If we're going to live in a world where countries can seize the shipping lanes, that will have a direct impact on Americans in the short term and the long term, and it's not going to begin with Iran doing it. The issue is that at the moment it has already begun. According to analysts and international observers, the 2026 Hormuz crisis is one of the most dangerous challenges to global energy transportation in decades. Maybe the most important question to ask in the coming year is whether that menace is thwarted or accepted – whether the toll Tehran is going to levy on the world's oil supply is permanent or it is dismantled.

The MSV Haji Ali is at the bottom of the sea off Oman. Its cargo is gone. Fourteen people on the ship are alive. The channel through which one-fifth of all the oil in the world goes, is still in the hands of Iran, in any real sense of the word.
