Iran sanctions ceasefire: Trump presses tariffs while pursuing nuclear limits talks

Donald Trump paired trade threats with a narrow diplomatic opening on Iran during a two-week ceasefire. Trump warned of steep tariffs for states supplying weapons to Tehran. At the same time, Trump signalled talks on sanctions relief and nuclear limits. The move suggested a mix of economic pressure and limited negotiation.

The temporary truce involved the United States, Iran and Israel, and aimed to cool a growing clash. Tehran said talks with Washington would begin in Islamabad on Friday. US strikes were paused under the arrangement. Israel supported the ceasefire framework, but said it did not cover fighting with Hezbollah in Lebanon.

Trump announced the tariff warning on Truth Social, focusing on arms support for Iran. Trump wrote: "A Country supplying Military Weapons to Iran will be immediately tariffed, on any and all goods sold to the United States of America, 50%, effective immediately. There will be no exclusions or exemptions!" The post framed tariffs as an immediate economic tool.

Alongside the tariff threat, Trump referred to ongoing contacts on sanctions and trade measures. Trump said Washington was discussing a structured plan with Tehran. Trump also claimed progress on defined items. "We are, and will be, talking Tariff and Sanctions relief with Iran. Many of the 15 points have already been agreed to," Trump stated.

Trump repeated strict nuclear conditions for any understanding with Tehran. Trump insisted there would be "no enrichment" by Iran. Trump also connected nuclear limits to cooperation on buried material. Trump wrote: "The United States will work closely with Iran, which we have determined has gone through what will be a very productive Regime Change!"

Trump added a further condition tied to sites said to be hit in last year’s US airstrike. Trump declared: "There will be no enrichment of Uranium, and the United States will, working with Iran, dig up and remove all of the deeply buried (B-2 Bombers) Nuclear 'Dust'." Earlier, Trump warned that "a whole civilisation will die tonight".

Donald Trump Iran sanctions and ceasefire: IRGC response and regional risks

Iran’s Islamic Revolutionary Guard Corps answered with distrust towards US assurances. In a Telegram statement, the Guards said it has "no trust" in Washington. The statement also stressed loyalty to "His Holiness Mojtaba Khamenei". It said "the Iranian nation's dedicated guards" had a "finger...on the trigger" to follow orders.

The Guards urged Gulf states to rethink security cooperation with the United States. The statement added: "The enemy has always been deceitful, and we have no trust in its promises, and we will respond to every aggression at a greater level." Separately, Israel said the ceasefire did not cover Lebanon, where over 1,500 died.

Event	Location	Key Detail
Ceasefire period	US, Iran, Israel	Two-week agreement to reduce tensions
Planned talks	Islamabad	US–Iran negotiations starting Friday
Lebanon conflict	Lebanon	Over 1,500 killed in fighting with Hezbollah

The ceasefire period left markets and regional actors weighing tariffs, nuclear conditions, and possible sanctions relief. Trump’s approach combined penalties for arms suppliers with talks on defined points. Yet the Guards’ scepticism and Israel’s continued operations in Lebanon kept risks elevated. The agreement remained limited, and its durability depended on actions during the truce.
