Pakistan Brokers US-Iran Nuclear Dialogue in Tehran

Pakistan is playing an intermediary role in ongoing negotiations between the United States and Iran over Tehran’s nuclear program, as officials involved in the process said they are expecting a major breakthrough. Iran’s Press TV reported that a senior Pakistani delegation arrived in Tehran on April 16, 2026, led by Army Chief Asim Munir, with the stated purpose of delivering messages from the U.S. to Iran’s leadership.

The talks are taking place against the backdrop of a conflict that officials described as having produced thousands of casualties. According to the information provided, the war began on February 28 with action by the U.S. and Israel, and it has resulted in more than 3,000 deaths in Iran. The same account said the conflict also triggered retaliatory actions against Gulf countries.

Negotiators are focused on two central nuclear questions : how long Iran would freeze uranium enrichment, and what would happen to its stockpile of 440 kilograms of highly enriched uranium. Mediators are described as trying to bridge a gap between proposals for a five-year pause and a 20-year pause. Options under discussion for the enriched material include transferring it internationally or diluting it.

Beyond the nuclear file, the negotiations are also addressing the Strait of Hormuz and compensation for wartime damage. Iran has reportedly closed the Strait of Hormuz, a development that has affected global oil prices. The talks also include the question of control over the waterway, which is a key route for energy shipments, and the issue of compensation tied to the conflict’s destruction.

A ceasefire has reduced but not eliminated tensions . A truce between Tehran and Washington on April 8 has paused attacks in Iran and the Gulf, according to the account, while Israeli military operations in Lebanon have continued. On April 15, U.S. President Donald Trump said the conflict was “very close to over,” and the White House said discussions were continuing and had been productive.

Even with diplomatic activity underway, the situation remains unsettled. S. Navy has imposed a blockade on Iranian ports in the Strait of Hormuz, and Iran’s military has criticized that move as a violation of the ceasefire.

The combination of a paused battlefield, continued regional military operations, and unresolved disputes over maritime access and nuclear constraints leaves key outcomes dependent on whether negotiators can finalize terms on enrichment duration, the handling of enriched uranium, and the Strait’s status.
