Key takeaway

Beijing protests the blockade in public and uses it in private, and the carve-out keeps both true.

Guo Jiakun, spokesman for the Chinese Foreign Ministry, called the US blockade 'dangerous and irresponsible' on Monday and said it 'will only exacerbate tensions and undermine the already fragile ceasefire agreement.' A second statement the following day repeated the language. Beijing, Guo said, would 'make efforts to help restore peace and stability.' Between the two statements, the Chinese-owned, US-sanctioned tankers Rich Starry and Elpis transited the strait of Hormuz under CENTCOM's non-Iranian-port carve-out without incident. China has filed no formal sanctions challenge.

Beijing's annual oil imports from Iran are roughly a sixth of total crude purchases, the volume that would have given a formal legal challenge both motive and standing. The diplomatic protest and the commercial transit are the same event from different angles. Beijing is arguing against the blockade in public while its tankers use the operational order's gaps in private. The rhetorical register is escalating; the operational register is not. China's leverage sits in what moves, not what is said.

The dual posture is stable only while the carve-out holds. If CENTCOM widens its operational order to include non-Iranian-port traffic, Beijing's quiet mode ends. A formal Chinese challenge at that point would move from press briefing to UN procedural filing and would test the blockade's legality in a way the unsigned presidential posture cannot defend. The same ambiguity that currently lets Chinese crude cross freely is the ambiguity that keeps Beijing's response below the threshold that would force a reckoning over the Pacific. Both sides benefit from the fog, for now.

Deep Analysis

In plain English

China's government publicly called the US blockade 'dangerous and irresponsible' two days running. Across the same two days, two Chinese-owned tankers that the US had already sanctioned for carrying Iranian oil sailed straight through the Strait of Hormuz; because the US military's written order only blocked ships going to Iranian ports, not all Chinese-owned ships. So China is doing two things at once: complaining loudly about the blockade in public, while quietly using the gap the US military left open to keep buying discounted Iranian oil. This is not contradictory from Beijing's perspective; protesting the principle while exploiting the practice is a consistent Chinese foreign policy approach. The tanker transits are the more important signal: they demonstrate that US secondary sanctions, without matching naval enforcement, have no coercive weight over Chinese commercial operations.

Deep Analysis

Root Causes

The structural condition enabling China's dual-register response is CENTCOM's non-Iranian-port carve-out, which was written precisely to avoid triggering Chinese-flag-state incidents. CENTCOM's lawyers understood that boarding a PLA-connected tanker in international waters without a presidential directive or UNSC mandate would create a bilateral incident with no legal defence. By excluding non-Iranian-port traffic, CENTCOM preserved the status quo on China while appearing to execute a blockade.

China's structural incentive is straightforward: Iranian oil at a discount provides roughly 15 per cent of its total crude imports. The dark-fleet architecture Beijing developed since 2022; sanctioned vessels operating outside Western insurance and financial systems; was specifically designed to absorb this kind of commercial environment. The blockade's carve-out is an accidental gift to a supply chain China has been building for four years.

Source Landscape

This story draws on neutral-leaning sources

Primary parallel: During the 1980-88 Iran-Iraq War, China supplied both sides simultaneously while maintaining neutral diplomatic positions with both Tehran and Baghdad. Chinese state arms companies (Norinco, CATIC) sold weapons to Iran while China's government called publicly for peace; the commercial and diplomatic registers were independently managed. The current pattern; tankers transit while spokespersons condemn; replicates this dual-register tradition with contemporary instruments.

Counter-parallel: In 2010-12, when the Obama administration imposed secondary sanctions on Chinese banks doing business with Iran, Beijing initially protested and then quietly complied: Bank of Kunlun was designated, Chinese financial institutions withdrew from Iran transactions, and oil import growth slowed.

The secondary-sanction mechanism worked. The difference now is that China's Iran imports are conducted through a sanctioned dark fleet operating outside the formal financial system; the SWIFT-based pressure point that worked in 2012 does not reach these vessels.

Consensus view: Fudan University's Zhao Mingsheng and the Shanghai Institutes for International Studies (SIIS) both characterise Beijing's dual-register response; diplomatic condemnation plus commercial transit; as 'strategic ambiguity with Chinese characteristics': Beijing extracts maximum economic benefit from the CENTCOM carve-out while maintaining the diplomatic posture of opposition.

The key mechanism is that Beijing has filed no formal sanctions challenge against the CENTCOM operational order, meaning the dual tanker transit is legally unchallenged and commercially exploitable. China's leverage sits entirely in what moves, not what is said.

Counter-view: Tsinghua University's Yan Xuetong, China's most hawkish international relations theorist, argues that Beijing's rhetorical register is not merely performative; it is a sovereignty signal.

By publicly condemning the blockade twice in 48 hours while transiting the carve-out, China is communicating that it will not accept secondary sanctions on its tankers without retaliation, while simultaneously demonstrating that the CENTCOM order is inadequate to actually stop Chinese commercial interests. The condemnation is a soft enforcement boundary; the transit is the test of it.

Key tension: Whether Beijing's current posture; loud protest, quiet commercial exploitation; is stable if CENTCOM widens its operational order to include non-Iranian-port sanctioned traffic (which would stop Rich Starry-class transits), or whether that scenario triggers Chinese measures against US commercial interests in the Pacific.

This Event

China condemns the blockade it uses

Beijing's rhetorical escalation is running in the opposite direction from its operational posture, because the carve-out CENTCOM wrote lets Chinese tankers transit without any commercial cost to contesting it.

Different Perspectives

Shipping and insurance industry

UKMTO counted about 20 US-facilitated Hormuz transits a day to 11 September against only 6 visible on AIS, with traffic still around 90% below the 138-a-day pre-war baseline. War-risk underwriters cannot price hulls they cannot see, or resolve whether the tanker El Gaia hit a mine, as Iran claims, or a missile and drone, as CENTCOM says.

European refiners

European refiners, including Poland's Orlen, absorbed a roughly $26 gap between Dated Brent at $130.80 on 15 September and ICE Brent futures settling at $103.87 on 18 September, a spread that widened from $13.45 on 9 September rather than newly opening. Their futures hedges no longer cover what they now pay for physical barrels.

Saudi Arabia

Saudi Aramco zeroed European term customers' October allocations and rerouted roughly 60 million barrels to Asia through Ras Tanura and Sohar, using Red Sea and Gulf terminal capacity built years ago to cut Hormuz exposure. Riyadh reallocated existing supply rather than negotiating a shortfall with Europe.

Qatar

Qatar's energy minister Saad al-Kaabi told Bloomberg at the Qatar Economic Forum on 20 September that Bessent's two-year Hormuz-obsolescence forecast is wrong, and that Doha has deliberately built no bypass pipeline. Qatar's gas exports run through one waterway by choice, not oversight.

Iran (foreign ministry and Majlis)

Iran's foreign ministry and 130 Majlis deputies moved toward NPT withdrawal this week, with lawmaker Hossein-Ali Haji Deligani filing a triple-urgency bill on 20 September that Speaker Qalibaf has not yet scheduled. Tehran treats treaty membership as leverage still on the table, not yet spent.

Russia and China

Moscow and Beijing vetoed the Panel of Experts' renewal, maintaining Resolution 2231 lapsed in October 2025 and the 2025 snapback was never validly triggered, so the sanctions architecture the Panel enforces has no current legal standing. Both governments frame the veto as upholding law, not shielding Tehran.
