US President Donald Trump has announced a new campaign of economic pressure against Iran, warning foreign governments that maintain commercial and energy ties with Tehran that Washington will target third parties offering support to the regime.
Trump described the upcoming phase of measures against Iran as an economic D-Day, warning that the United States will target not only the Iranian economy but also foreign nations providing financial or trade assistance to Tehran.

According to Reuters, the White House strategy comes while Middle East tensions remain high, placing sanctions, energy markets, and security in the Persian Gulf at the center of the American initiative. US Treasury Secretary Scott Bessent stated that Washington is preparing the toughest sanctions in history against Iran, calling on international allies and partners to back the effort.
The Trump administration aims to shift pressure from military action to economic isolation, seeking to restrict Iranian crude oil exports and deprive Tehran of critical state revenues. The policy creates a broader commercial front, placing nine major Iranian trading partners under intense scrutiny from Washington.
Major crude buyers and Chinese trade networks
China remains the largest single obstacle to the American economic strategy, serving as the primary buyer of Iranian crude oil and absorbing the vast majority of Tehran's energy exports. According to Reuters, China imported approximately 1.38 million barrels of oil per day from Iran in 2025.
Chinese entities utilize complex financial and trade networks that make the enforcement of American sanctions particularly difficult. The Trump administration warned that continuing this trade could prompt new sanctions against Chinese companies and banking institutions that facilitate transactions with Iran. However, direct economic confrontation with Beijing risks escalating tensions between the United States and China over the Middle East crisis.
Gulf banking channels and United Arab Emirates trade freezes
The United Arab Emirates has historically served as a vital financial gateway for Iran, with Dubai banks holding substantial deposits linked to Iranian business interests over many years. A significant portion of those assets is currently frozen under existing US sanctions.
Data from the World Trade Organization indicates that the United Arab Emirates accounted for roughly 30 percent of Iran's imports in 2024, valued at 21 billion dollars. The UAE also absorbed 13 percent of Iranian exports, while bilateral non-oil trade reached 6.6 billion dollars in 2024, consisting predominantly of re-exports.
That commercial relationship faced an abrupt interruption this week when the United Arab Emirates suspended all financial and economic transactions with Iran until further notice. Authorities in Abu Dhabi cited military escalation by Tehran and the potential threat of missile attacks for the immediate suspension.
Energy dependence in Turkey and Iraq
Turkey represents another critical link in Iran's regional trade network, with annual bilateral trade between Ankara and Tehran valued between 5 billion and 6 billion dollars. Energy cooperation forms a major component of that commercial activity.
The Turkish government has previously attempted to balance its economic ties with Tehran against diplomatic pressure from Washington, avoiding complete alignment with American sanctions. Trump's renewed campaign places increased pressure on Ankara as Washington seeks to eliminate financial lifelines to Iran.
Iraq occupies a particularly delicate position due to its concurrent reliance on both Washington and Tehran. Despite maintaining close security ties with the United States, Baghdad relies heavily on Iranian energy, purchasing between 4 billion and 5 billion dollars worth of natural gas annually from Tehran to supply its domestic power grid. Stricter sanctions threaten to destabilize Iraq's energy sector.
Mediators and informal cross border commerce
Oman has maintained friendly diplomatic ties with Iran for decades, maintaining relations that predate the 1979 Islamic Revolution. Officials in Muscat have frequently served as diplomatic mediators between Iran and Western powers, including the United States. Bilateral trade in goods between Oman and Iran reached 1.5 billion dollars in 2025 and totaled 345 million dollars during the first four months of 2026.
In South Asia, Pakistan faces severe economic risk from any US action targeting nations that trade with Iran. Officials in Islamabad and Tehran previously pledged to raise bilateral trade to 10 billion dollars. Although formal commerce virtually ceased after earlier sanction rounds, informal trade has sustained bilateral imports and exports at approximately 4 billion dollars according to unofficial data.
Border communities in Pakistan and Iran have engaged in informal trade for years, exchanging Iranian oil for Pakistani wheat, rice, live animals, and pharmaceutical products through unrecorded channels.
Contracting commercial ties in India and the Caucasus
India's trade relationship with Iran contracted sharply in 2020 when Washington intensified sanctions against Tehran. Bilateral trade plummeted by more than two-thirds from 17 billion dollars to approximately 4.8 billion dollars in the 2019-2020 fiscal year. Commercial volume declined further to 1.63 billion dollars in the 2025-2026 fiscal year.
Indian exports of 1.3 billion dollars make up the bulk of that trade, consisting primarily of food staples including cereals, tea, coffee, and spices. Indian officials contend that these shipments are conducted for humanitarian purposes and should remain exempt from American sanctions.
In the Caucasus region, Iran accounted for 3.6 percent of Armenia's total foreign trade in 2025, with transactions valued at 768 million dollars. Bilateral trade reached 371.4 million dollars in the first half of 2026, marking an 8.4 percent increase year-over-year. Approximately 20 percent of Armenia's total external commerce transits through Iranian territory.
Armenia and Iran operate an ongoing gas for electricity swap agreement. Under the mechanism, Armenia imports Iranian natural gas to fuel domestic power generation and returns a portion of the generated electricity to Iran.
In neighboring Azerbaijan, trade with Iran rose 4.5 percent during the first half of 2026 to reach 312.6 million dollars, compared to 299.1 million dollars during the same period in 2025. Azerbaijani imports from Iran rose 1.5 percent to 297 million dollars, while Azerbaijani exports to Iran increased 2.4 times to reach 15.6 million dollars.
The White House strategy seeks to force international partners to choose between maintaining economic ties with Tehran or retaining access to the American economy. The central question remains whether expanded sanctions can effectively weaken the Iranian economy or whether they will spark broader geopolitical disputes with major trading partners such as China, Turkey, and Iraq.
