US Vice-President JD Vance has indicated that Washington and Tehran are nearing an agreement to ease the ongoing conflict but cautioned that significant differences remain unresolved. Speaking to the BBC, Vance described the negotiations as “very close” while stressing it was “too early to say when or if” a final deal would materialise.

The remarks come amid heightened diplomatic activity as both sides work to extend a fragile ceasefire and address Iran’s nuclear programme.

Key Sticking Points Remain

Disagreements persist over language related to uranium enrichment and the future of Iran’s nuclear activities. The US has long insisted that Iran halt production of highly enriched uranium and dispose of existing stockpiles to prevent any path toward nuclear weapons. Vance noted that negotiators are still ironing out several textual issues.

A proposed framework reportedly includes a 60-day extension of the current ceasefire and the launch of formal talks on Iran’s nuclear future. However, Iran’s semi-official Tasnim news agency has stated that no agreement has been finalised or confirmed by Tehran’s leadership.

US Rejects Iranian Claims on Aircraft

Tensions spiked after Iranian state television claimed that its forces downed a US aircraft in Bushehr province’s Jam governorate. US Central Command (CENTCOM) firmly denied the assertion, calling it unfounded. 

The incident highlights the fragile nature of the truce even as diplomatic efforts continue. Local authorities in Iran, including Governor Masoud Tangestani, had earlier publicised the claim.

White House Optimism Grows

Despite the hurdles, senior US officials have struck a cautiously optimistic note. White House Deputy Chief of Staff Stephen Miller described Iranian concessions as “significant, material, and dramatic,” particularly regarding the reopening of the Strait of Hormuz. 

Treasury Secretary Scott Bessent signalled that while progress has been made, the US will not rush to ease sanctions or release frozen assets. President Donald Trump maintains firm “red lines,” especially on preventing Iran from acquiring nuclear weapons.

Regional Diplomacy in Play

Pakistan continues to play a mediation role. Foreign Minister Mohammad Ishaq Dar is scheduled to meet US Secretary of State Marco Rubio in Washington today. Iranian President Masoud Pezeshkian has thanked both Pakistan and Malaysia for their efforts, reaffirming Tehran’s commitment to diplomacy and stronger ties with Muslim and neighbouring nations.

Meanwhile, senior Iranian official Ali Bagheri Kani held discussions in Moscow with counterparts from Egypt and Brazil on the West Asia situation.

Impact on Global Markets

Oil prices edged lower on hopes of a breakthrough. Brent crude fell to around $93.36 per barrel, while WTI crude dropped to $88.27. However, Vance’s measured comments limited sharper declines, reflecting market caution over the deal’s final status.

Broader Conflict Context

The nearly four-month-long confrontation has seen multiple flashpoints. The US recently sanctioned Iran’s new Persian Gulf Strait Authority and networks allegedly funding the IRGC. Iran’s Supreme Leader has accused the US and Israel of attempting to destabilise the country internally after failing militarily.

In a related development, Democratic Senator Chris Murphy criticised the Trump administration’s approach, warning that threats to Oman over potential support for Iranian toll collection in the Strait of Hormuz signal a conflict spiralling out of control.

What Lies Ahead

Negotiators from both sides continue behind-the-scenes work. While 95 percent of issues may have been addressed according to some reports, the remaining gaps—particularly on enrichment terms—will prove decisive. 

Any final agreement would require approval from President Trump and Iran’s top leadership. Until then, officials on both sides are maintaining that “there is no deal until there is a deal.”

The outcome could significantly influence regional stability, global energy flows, and the broader West Asia security architecture. For now, cautious optimism prevails in Washington even as ground realities remain complex.
