U.S. and China Agree to Keep Hormuz Toll-Free Amid Iran War
On 13 May, the U.S. State Department announced that Washington and Beijing agreed no country should levy shipping tolls in the Strait of Hormuz. The understanding followed talks between U.S. Secretary of State Marco Rubio and Chinese Foreign Minister Wang Yi ahead of a planned Trump–Xi summit in Beijing.

The United States and China have reached a significant, if narrowly framed, understanding on maritime traffic through one of the world’s most sensitive waterways. On 13 May 2026, the U.S. State Department announced that both countries agreed no nation should impose shipping tolls in the Strait of Hormuz, a critical chokepoint for global oil and gas flows. The agreement followed discussions between U.S. Secretary of State Marco Rubio and Chinese Foreign Minister Wang Yi, held in advance of a scheduled summit in Beijing between U.S. President Donald Trump and Chinese President Xi Jinping.
This development comes against the backdrop of a protracted and costly war between the United States and Iran, during which Iran has already disrupted regional shipping and, at times, closed or threatened to close the Strait. The imposition of tolls, escort fees, or other de facto tariffs by any littoral state or coalition would further inflame tensions and impose additional costs on global trade at a time of elevated energy prices and supply uncertainty.
For Washington, securing Chinese endorsement of a toll‑free Hormuz serves a dual purpose. First, it underpins a core U.S. interest in freedom of navigation and open sea lanes, principles central to its global maritime strategy. Second, it enlists China—an increasingly influential Gulf trading partner and major energy importer—as a stakeholder in preventing further weaponization of the strait. By aligning with Beijing on this specific issue, the U.S. aims to limit Iran’s leverage and discourage other regional actors from exploiting the conflict economically.
Beijing’s calculus is driven largely by energy security. China imports substantial volumes of crude from Gulf producers, and disruptions in Hormuz translate directly into economic and political risks at home. A confidential U.S. intelligence assessment cited on 13 May suggested China is already extracting strategic advantages from the Iran war—selling arms to Gulf states, helping manage energy shortages after Iranian disruptions, and increasing its diplomatic footprint. Supporting a toll‑free Hormuz allows China to position itself as a protector of global commons and a responsible major power, without explicitly siding with Washington’s broader Iran policy.
The main stakeholders are the U.S., China, Iran, Gulf Cooperation Council states, and key energy importers in Asia and Europe. Iran has historically used the threat of closing Hormuz as a bargaining chip, and in recent months has reportedly restricted traffic or imposed ad hoc constraints under the guise of security measures. Gulf states, particularly Saudi Arabia and the UAE, depend on Hormuz for hydrocarbon exports but have invested in alternative routes such as pipelines to the Red Sea. Nonetheless, a major disruption in the strait would still have global ramifications.
The agreement does not in itself guarantee security in the strait—naval incidents, mining, harassment of tankers, and drone or missile attacks remain live risks. It also does not address sanctions regimes or insurance premiums, both of which significantly affect shipping costs. However, it signals that the two largest global economies share a common interest in preventing any additional charges that could fragment maritime governance or normalize the idea of pay‑to‑pass regimes in strategic chokepoints.
From a geopolitical standpoint, this narrow cooperation may marginally ease U.S.–China frictions in the Middle East theater, even as their competition intensifies elsewhere. It may also limit Iran’s ability to rally external partners behind any future attempts to condition transit on political concessions or to recoup war losses through tolls.
Outlook & Way Forward
In the immediate term, attention will shift to how Iran and key Gulf states respond to the U.S.–China position. Tehran could dismiss the understanding as illegitimate interference or attempt to test its durability through renewed harassment of shipping or threatened closures framed as security measures rather than tolls. Conversely, Iran may calibrate its actions to avoid alienating China, whose economic and diplomatic support it values.
For Washington and Beijing, the practical next step will be to translate their shared stance into operational behavior, potentially through quiet naval coordination, de‑confliction mechanisms, or parallel diplomatic messaging to Gulf capitals. While a formal joint statement or UN initiative on Hormuz tolls is possible, both sides may prefer more flexible, low‑visibility channels that preserve room for maneuver.
Longer term, the agreement raises the question of whether similar understandings could emerge around other maritime chokepoints where U.S.–China interests overlap, such as Bab al‑Mandab or the Malacca Strait. Analysts should watch for any codification of norms regarding economic neutrality of key sea lanes, as well as for any Iranian efforts to circumvent the no‑toll principle via proxy actors, non‑tariff barriers, or cyber and hybrid disruptions to port and shipping infrastructure. The durability of this limited cooperation will be an indicator of how far pragmatic alignment can coexist with systemic rivalry between the U.S. and China.
