U.S. Vows “Toughest Sanctions In History” Against Iran, Urges China To Help Reopen Hormuz

Our take

The United States has announced what officials are characterizing as the “toughest sanctions in history” against Iran, a measure intended to complement existing restrictions and potentially avert escalated military conflict. Bessent indicated these actions aim to exert significant economic pressure. Simultaneously, the U.S. is urging China to facilitate the reopening of the Strait of Hormuz, a critical waterway for global energy transport. Developments in the region, such as the increased naval presence—including the U.S. Navy’s deployment of the George Washington carrier—underscore the escalating tensions.
U.S. Vows “Toughest Sanctions In History” Against Iran, Urges China To Help Reopen Hormuz

The escalating tensions in the Persian Gulf, exemplified by the U.S. vow of “toughest sanctions in history” against Iran and the concurrent plea for China’s assistance in reopening the Hormuz Strait, represent a significant inflection point for maritime trade and global stability. These actions, intended to curb Iran’s nuclear program and regional influence, inevitably impact the critical chokepoints through which a substantial portion of the world's energy and goods flow. The situation is further complicated by the ongoing presence of naval forces in the region, as demonstrated by the recent deployment of the U.S. Navy aircraft carrier George Washington to the Arabian Sea [U.S. Navy Aircraft Carrier George Washington Reaches Arabian Sea As USS Lincoln’s 250-Day Deployment Ends] and the accompanying escort of LNG tankers by Russian warships along the Norwegian coast [Russian Warship Escorts Gazprom LNG Tanker Along Norwegian Coast As Arctic Shipping Season Peaks], highlighting the interwoven nature of geopolitical interests and maritime security. The potential for disruption necessitates a calibrated and data-driven approach to understanding and mitigating the risks.

The imposition of stringent sanctions, while aimed at achieving diplomatic objectives, carries inherent risks of unintended consequences for the global economy. The Hormuz Strait, a narrow waterway, is a crucial artery for oil shipments, and any impediment to its free passage could trigger significant price volatility and supply chain disruptions. Moreover, the involvement of China, a major economic power with its own strategic interests in the region, introduces another layer of complexity. China's participation in de-escalation efforts, or conversely, its continued support for Iran, will profoundly shape the trajectory of events. The proposed "Canal Project of the Century" [China’s ‘Canal Project Of The Century’ Build For $10 Billion Nears Launch] in Southern China, while intended to alleviate pressure on the Hormuz Strait in the long term, remains years from completion and cannot offer immediate relief. Our integrated data ecosystem is currently tracking vessel movements and trade flows through the Strait with real-time precision, allowing us to provide calibrated assessments of potential vulnerabilities.

The reliance on sanctions as a primary tool of foreign policy underscores the need for robust ocean intelligence to anticipate and respond to potential crises. Historically, sanctions have proven to be a blunt instrument, often impacting civilian populations and creating opportunities for illicit activities. The current strategy necessitates a deeper understanding of the maritime landscape, including shipping routes, port infrastructure, and the potential for alternative supply chains. Peer-reviewed research suggests that economic pressure alone is rarely sufficient to achieve lasting change, and a multifaceted approach that combines diplomacy, economic incentives, and credible security assurances is often required. The U.S. blockade, coupled with these new sanctions, creates a complex and potentially unstable environment. Longitudinal data analysis of shipping patterns and trade volumes will be critical for validating the effectiveness of these measures and identifying potential unintended consequences.

Ultimately, the situation in the Persian Gulf serves as a stark reminder of the interconnectedness of global systems and the critical role of the ocean in facilitating international trade and security. The future stability of this vital waterway, and the broader maritime domain, hinges on fostering collaborative partnerships, enhancing data transparency, and developing empirically validated strategies for conflict resolution. A key question moving forward is whether the combination of escalating sanctions and diplomatic efforts will prove sufficient to de-escalate tensions and prevent a return to large-scale military action, or if alternative, more sustainable pathways to regional stability can be forged.

US Vows “Toughest Sanctions in History” Against Iran, Urges China to Help Reopen Hormuz

The United States is preparing a new round of sanctions against Iran that Treasury Secretary Scott Bessent said would be the “toughest sanctions in history.”

Bessent said the new measures would work alongside the existing US blockade and could help avoid a return to large-scale military action.

“It is a one-two punch. We have the blockade, and we are going to have the toughest sanctions in history,” Bessent told CNBC on Thursday.

“It is going to work in Iran and we are going to collapse this regime,” he said, adding that he would hold a news conference on Monday to explain the measures.

The dispute has also pushed oil prices to more than three-week highs.

US presses China over Hormuz

Bessent called on China to cooperate with Washington’s efforts to reopen the Strait of Hormuz and bring down energy prices.

“We are confident that everyone wants the Strait reopened, and for energy prices to come back down,” he said.

He pointed to China’s dependence on energy from the Gulf, saying about 50% of the country’s energy comes from the region.

China is also the main buyer of Iranian crude. It accounted for more than 80% of Iran’s shipped oil in 2025, according to data from analytics firm Kpler.

When asked whether the United States could target China for continuing to do business with Iran, Bessent did not give details, saying some discussions were better held privately.

Further US action against Chinese companies dealing with Iran could have wider economic consequences, as China is also a major supplier to the United States, including of critical rare-earth minerals.

China rejected the US approach. A spokesperson for the Chinese embassy in Washington said sanctions and pressure would not help solve the problem and urged all sides to act responsibly and pursue political and diplomatic solutions.

Trump warns countries against supporting Iran

Bessent’s comments came a day after President Donald Trump warned countries against providing Iran with any type of “lifeline”.

Trump said the US campaign would target Iran’s economic networks, including oil-smuggling operations, financial transfers, exchange houses, ship registries and front companies.

He called the effort an “ECONOMIC D-DAY” and warned that countries providing financial, commercial or government support to Tehran could face “tremendous economic consequences”.

Trump has repeatedly said Iran must not be allowed to acquire a nuclear weapon. Iran has rejected Washington’s pressure campaign.

Iranian Foreign Minister Abbas Araghchi criticised Trump’s latest comments and accused him of trying to divert attention from economic problems in the United States, including rising debt and interest costs.

Araghchi said Trump’s so-called “Economic D-Day” would bring further “defeat” and “enmity of Iranians” if Washington continued to increase sanctions.

Iran calls US sanctions ‘economic terrorism’

Iran’s foreign ministry accused the United States on Thursday of using sanctions that affect the rights of Iranian citizens.

The ministry said in a statement carried by state media that the US economic sanctions amounted to “economic terrorism” and “crimes against humanity”. It said those responsible for the sanctions should face trial and punishment.

Iran has faced extensive US-led sanctions for decades, dating back to the 1979 Islamic Revolution.

Bessent said Washington’s strategy of maximum economic pressure could reduce the possibility of another large-scale military campaign.
