Ceasefire revived diplomacy — with big gaps
The truce has reopened diplomacy but negotiators still face wide disagreements over Iran’s nuclear rights and monitoring, so a durable deal feels distant. Oman reportedly hosted multiple rounds of talks before the fighting, with Washington offering long‑term fuel solutions but demanding zero enrichment while Tehran insisted on enrichment rights and tight inspections. At the same time, the White House threatened a new 50% tariff on countries supplying arms to Iran, a move that could strain the very partnerships diplomats need to secure a lasting settlement.

The shooting paused, and the talking restarted, but the gap between Washington and Tehran is still the kind you can drive a convoy through. A two-week ceasefire was announced on April 8, 2026, and talks are expected to begin on Friday, April 10, while both sides treat the pause as temporary and conditional. (time.com) Before the fighting, Oman had already been shuttling messages and hosting quiet rounds of diplomacy between the United States and Iran. That matters because the current talks are not starting from zero; they are reopening an argument that was already stuck on the same core points. (bbc.com) The hardest argument is over uranium enrichment, which is the step that turns raw nuclear fuel into material usable for reactors and, at higher levels, potentially for bombs. The United States has reportedly demanded zero enrichment inside Iran, while Tehran has insisted that enrichment on Iranian soil is a sovereign right. (bbc.com) Washington’s reported fallback idea was a long-term fuel arrangement, meaning Iran would get reactor fuel from outside suppliers instead of making it itself. Tehran has resisted that formula before because imported fuel leaves Iran dependent on foreign governments that can delay, cancel, or condition deliveries. (bbc.com) The second fight is over inspections, which are the cameras, seals, site visits, and accounting rules used to check whether nuclear material is going where governments say it is going. The International Atomic Energy Agency is the body that runs that system in Iran, and its monitoring record has become one of the central tests in any new deal. (iaea.org) That inspection issue is not abstract. The International Atomic Energy Agency still maintains dedicated monitoring and verification files on Iran, including board reports from February, May, and September 2025, which shows how unresolved the oversight question remained even before this week’s ceasefire. (iaea.org) Then the White House added a second pressure track. President Donald Trump threatened a new 50 percent tariff on countries supplying military weapons to Iran even as his administration said it was open to nuclear talks, tying diplomacy to a trade penalty aimed at Iran’s foreign backers. (scmp.com) (visaverge.com) That creates an awkward contradiction for negotiators. China was publicly credited by Trump for helping with the truce, but China is also exactly the kind of outside power that could be pulled into a tariff fight if Washington broadens penalties around Iranian arms ties. (scmp.com) The ceasefire itself is also fragile on the ground. South China Morning Post reported that Tehran kept the Strait of Hormuz closed and warned it could walk away from the deal if Israeli attacks in Lebanon continued, which means the nuclear file is now tied to regional flashpoints far beyond the negotiating room. (scmp.com) So the diplomacy is back, but it is back with the same old deadlock plus a new tariff threat and a live regional war in the background. A temporary ceasefire can buy days, and Oman can buy meetings, but neither side has yet moved on the two questions that decide whether any deal lasts: who gets to enrich uranium, and who gets to verify it.
