Following Tuesday’s agreement on a two-week ceasefire with Iran, U.S. President Donald Trump warned countries against supplying weapons to Tehran while simultaneously hinting at possible sanctions relief as the two sides head to April 10 negotiations in Islamabad.
Through a series of posts on Truth Social, Trump outlined a two-pronged U.S. strategy: offering incentives to encourage cooperation while maintaining firm restrictions on Iran’s nuclear program.
He reiterated that Tehran would not be permitted to enrich uranium and emphasized ongoing U.S. oversight of sensitive nuclear sites, which remain under “very exacting satellite surveillance.”
In a post, he 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!”
Trump described the emerging framework with Iran as “very productive” and noted that several elements of his broader 15-point agreement—conveyed through Pakistan last week—have already been settled.
He added that Washington would assist in securing and removing buried nuclear material, underscoring the administration’s dual approach of engagement and caution.
Reaffirming the U.S. position against Iran pursuing a nuclear weapons program, 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! 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.’ It is now, and has been, under very exacting Satellite Surveillance (Space Force!). Nothing has been touched from the date of attack.
“We are, and will be, talking Tariff and Sanctions relief with Iran.”
The International Atomic Energy Agency, the UN’s body responsible for monitoring nuclear activity, reports that Iran possesses roughly 972 pounds of uranium enriched up to 60 percent. While this is below the roughly 90 percent threshold generally regarded as weapons-grade, it represents a level of enrichment far higher than that used for ordinary nuclear power generation.

Pakistan’s diplomatic efforts were central to reaching the ceasefire. In the days leading up to Trump’s self-imposed deadline, Islamabad maintained close coordination with both Washington and Tehran, advocating for a pause in hostilities and proposing measures such as reopening the Strait of Hormuz and structured talks to build trust.
The efforts culminated in an agreement just hours before the threat of U.S. military action, effectively averting further escalation.
Vice President J.D. Vance, alongside senior Trump advisors including Witkoff and Jared Kushner, is expected to represent the U.S. at Friday’s Islamabad talks. Their participation highlights the priority Washington is placing on transforming the temporary truce into a more sustainable peace framework.

Trump also signaled economic engagement, writing that “many of the 15 points have already been agreed to” and describing the ceasefire as “a big day for world peace.” He highlighted the potential for reconstruction in Iran and pledged U.S. assistance with shipping flows in the Strait of Hormuz.
At the same time, the president issued a stern warning: any country supplying military equipment to Iran would face immediate tariffs of 50% on all exports to the U.S., with “no exclusions or exemptions.”
The Strait of Hormuz remains a particularly contentious issue. Iran has indicated it intends to maintain authority over maritime traffic after the conflict ends, while allowing safe commercial passage under the current temporary ceasefire. This underscores the broader debate over sovereignty and control in the region.
“The United States of America will be helping with the traffic buildup in the Strait of Hormuz. There will be lots of positive action! Big money will be made. Iran can start the reconstruction process,” Trump wrote in a post.
“We’ll be loading up with supplies of all kinds, and just ‘hangin’ around’ in order to make sure that everything goes well,” he added.
Meanwhile, Israel has supported Trump’s ceasefire with Iran but clarified that it does not extend to its operations in southern Lebanon. Israeli officials have expressed backing for halting U.S.–Iran hostilities yet insist that its offensive campaign against Hezbollah and allied groups will continue outside the ceasefire framework.
