Deputy Prime Minister and Foreign Minister Ishaq Dar spoke with Iranian Foreign Minister Abbas Araghchi, with the regional situation and Pakistan’s ongoing diplomatic efforts coming under discussion, the Foreign Office (FO) said on Monday.

“Discussion focused on the regional situation and Pakistan’s ongoing diplomatic efforts for peace and stability in the region,” the FO said, adding that the call took place late Sunday night.

It added that the Iranian foreign minister appreciated Pakistan for its “constructive role and sincere mediation efforts between the parties”.

The FO said that Dar reaffirmed Pakistan’s continued commitment to promoting constructive engagement and underscored that “dialogue and diplomacy remain the only viable path toward the peaceful resolution of issues and achieving lasting peace and stability in the region and beyond”.

The development comes after Tehran said on Sunday that the United States had responded to its new peace proposal. Iranian state media said Washington had conveyed its response to Iran’s 14-point proposal via Pakistan, and that Tehran was now reviewing it.

Subsequently, US President Donald Trump said that his representatives were having “very positive discussions” with Iran that could “lead to something very positive for all”.

Negotiations between the US and Iran had been deadlocked since a ceasefire, brokered by Pakistan, came into effect on April 8, with only one round of direct peace talks held in Islamabad so far.

US news website Axios reported, citing two sources briefed on the proposal, that it set “a one-month deadline for negotiations on a deal to reopen the Strait of Hormuz, end the US naval blockade and permanently end the war in Iran and in Lebanon”.

Separately, Al Jazeera reported, citing sources, that the proposal envisaged three main stages, aiming to “transform the ceasefire into an end to the war within 30 days”.

According to the report, the proposal “envisions a pledge of nonaggression, including from Israel, to ensure there’s no return to war and an end to fighting throughout the Middle East”.

It said the proposal suggested the gradual reopening of the Strait of Hormuz in the first phase, as well as lifting the US blockade of Iranian ports.

Under the proposed plan, Tehran would take charge of dealing with sea mines, the report said.

It added that the second phase was proposed to include “Iran’s return to uranium enrichment after the time limit at 3.6 per cent in accordance with the ‘zero-storage principle’“.

Moreover, the plan includes the US and Israel refraining from attacking Iran and its allies in exchange for Iran refraining from launching strikes, the report said, adding that Iran had also rejected “dismantling nuclear infrastructure or destroying Iran’s facilities”.

“Lifting sanctions includes the gradual release of frozen funds,” it said.

In the third phase, Tehran proposed to enter “into a strategic dialogue with Arab neighbours and building a security system that includes the entire Middle East”, the report stated.
