Iran has denied agreeing to new nuclear inspections as part of recent talks with the United States, contradicting claims from Washington that the two sides reached an understanding on nuclear oversight during peace negotiations in Switzerland.
Iran’s Foreign Ministry rejected the suggestion that Tehran had accepted additional inspections, raising fresh uncertainty over the future of a fragile diplomatic arrangement between the two countries.
The dispute emerged after U.S. Vice President JD Vance said Washington and Tehran had reached progress on nuclear issues, including steps related to monitoring Iran’s nuclear programme.
Iranian officials, however, said no agreement had been reached that would allow expanded inspections, creating a major disagreement over one of the most sensitive issues in the negotiations.
The inspection question is considered central to any long-term agreement because international monitoring has historically been a key requirement for verifying Iran’s nuclear activities.

Analysts warned that without clear and enforceable inspection commitments, the emerging U.S.-Iran deal could face serious challenges before the current diplomatic roadmap reaches its conclusion.
The disagreement comes as Washington has taken a significant step toward easing economic pressure on Tehran by granting a temporary waiver allowing Iranian oil exports.
The U.S. Treasury authorised a 60-day sanctions exemption that permits Iran to produce and sell crude oil, petrochemicals and petroleum products in dollar-denominated transactions.

The waiver represents one of the most substantial relaxations of U.S. oil sanctions on Iran in decades and could provide Tehran with billions of dollars in additional revenue.
The move has been viewed as a tangible outcome of the negotiations, even as disagreements over nuclear oversight remain unresolved.
Energy analysts estimate that the sanctions relief could allow Iran to increase oil sales and access previously restricted revenues, providing economic support for the country after years of pressure from international sanctions.
However, the lack of agreement on inspections threatens to undermine confidence in the broader diplomatic process.
The United States has long argued that strong monitoring mechanisms are necessary to ensure Iran’s nuclear programme remains peaceful, while Tehran has repeatedly opposed measures it considers excessive or politically motivated.
The latest tensions highlight the difficulty of reaching a comprehensive agreement that satisfies both sides.

Washington is seeking guarantees that Iran’s nuclear activities remain limited and transparent, while Tehran has prioritised sanctions relief and recognition of its right to pursue civilian nuclear activities.
The two countries had shown signs of improved dialogue following recent talks, but the conflicting statements over inspections suggest significant gaps remain.
Analysts say the success of the 60-day framework will depend on whether both sides can resolve disagreements over verification, compliance and the scope of sanctions relief.
Failure to establish a clear inspection arrangement could weaken support for the agreement and increase the risk of renewed confrontation.
For now, the oil sanctions waiver provides a short-term economic benefit for Iran, but the future of the broader U.S.-Iran understanding remains uncertain as both governments continue to present different accounts of what was agreed.
