US President Donald Trump has launched what he termed an “economic D-Day” against Tehran, threatening to impose severe financial penalties on any nation that provides an economic “lifeline” to Iran. This aggressive stance marks the latest attempt by the administration to leverage US economic might to achieve foreign policy goals, following a series of contentious trade wars earlier in his second term.
In a post on his Truth Social platform, Trump characterized the campaign as “the most crushing economic operation ever taken against any country.” He warned of “tremendous economic consequences” for entities facilitating Iranian efforts to bypass sanctions, specifically targeting activities such as oil smuggling, ship registries, cash transfers, swap lines, exchange houses, and the use of front companies. “It all needs to stop NOW,” the president declared.
However, experts remain skeptical about the feasibility of this pressure campaign. Paul Musgrave, an associate professor of government at Georgetown University in Qatar, noted that it will be difficult for Trump to execute this strategy effectively. Musgrave explained that the president is attempting to unilaterally enforce sanctions that historically require multilateral coordination, which would necessitate the cooperation of China, Russia, and the other permanent members of the UN Security Council.
The diplomatic landscape is further complicated by recent regional developments. The United Arab Emirates, a vital hub for Iranian imports and commercial access, recently declared an indefinite trade embargo on Tehran following allegations that the Iranian military fired two ballistic missiles at its territory. Nader Habibi, a professor of Middle East economics at Brandeis University, suggested that the US likely induced this move and may seek to pressure other key trade partners, including China.
Disrupting the China-Iran trade relationship presents significant hurdles. Despite China purchasing 80 percent of Iran’s oil exports in 2025, according to data from Kpler, many Chinese refineries are independent and operate with minimal reliance on the US financial system. Furthermore, while the US Treasury has threatened to sanction major Chinese banks that process Iranian funds, such a move could provoke a retaliatory response during a delicate diplomatic period.
Yu Jie, a senior research fellow at Chatham House, argued that the threat to target Iran’s economic allies will not fundamentally alter China’s existing trade ties. She noted that Beijing is currently seeking a temporary truce with Washington, and while the Gulf conflict will be a topic of discussion during President Xi Jinping’s upcoming visit to the US, it is not expected to be the primary focus. Chinese Foreign Ministry spokesman Lin Jian has publicly pushed back, stating that additional sanctions will not resolve the underlying issues and calling for diplomatic solutions.
Russia presents a distinct challenge for Washington. Although Russia is a smaller trade partner for Iran than China, the two nations have cultivated deep commercial and military ties that function outside Western influence. In January 2025, the two states signed a 20-year partnership treaty, which helped drive trade volume to $4.8 billion in the first 11 months of that year, as reported by Russian Energy Minister Sergey Tsivilev. Beyond oil, reports indicate that Russia and Iran have exchanged military equipment via the Caspian Sea, with NBC News citing a European document claiming that Russia recently supplied drone components, ammunition, and TNT to Tehran.
In response to the US campaign, Iranian Foreign Minister Abbas Araghchi dismissed the measures as a continuation of “failed policies” that will lead to “further defeat.” Writing on X, he condemned the actions as “US economic terrorism” that threatens global sovereignty and the international economy.
Tehran is actively seeking to mitigate the impact of these “suffocating” sanctions by expanding its financial reach. Central Bank Governor Abdolnaser Hemmati announced last week that Iran intends to join the BRICS New Development Bank (NBD) to access financing outside Western markets. Iran is also exploring bilateral and trilateral monetary cooperation with fellow BRICS members, advocating for transactions in local currencies. While the NBD has yet to comment on the accession process, analysts like Ali Akbar Dareini of the Center for Strategic Studies in Tehran remain defiant, stating that Trump is trapped in a conflict he can neither win nor exit. The report also notes that russia is already under sweeping US sanctions and operates largely outside the US-led economic framework. The report also notes that china, meanwhile, has repeatedly shown it is willing to ignore US sanctions when doing so serves its own economic interests. The report also notes that according to data from analytics firm Kpler, going after China’s oil refineries is often challenging because most are independent with little reliance on the US financial system, while China bought 80 percent of Iran’s shipped oil in 2025. The report also notes that “China calls on relevant parties to take responsible measures and solve the issues through diplomatic and political means,” said Lin. The report also notes that the US has tried to keep tensions with China at bay ahead of Chinese President Xi Jinping’s planned visit to Washington next month. The report also notes that during that and two other potential meetups between the leaders later this year, “prolonged conflict in the Gulf is one of the items both sides will discuss,” said Yu, “but it won’t be the most important item”. The report also notes that “Trump is stuck in a war he can’t win and he can’t get out of,” Dareini told.
