The quadrilateral meeting would take place on Sunday-Monday, a senior Pakistani foreign ministry official told AFP on Saturday.
He noted that delegations are expected to arrive by Sunday evening, though the exact level of representation had yet to be confirmed.
The Egyptian foreign ministry said Minister Badr Abdelatty travelled to Islamabad on Saturday to join his counterparts from Pakistan, Saudi Arabia, and Turkey in a new push to de-escalate the ongoing US-Israeli war on Iran.
The meeting will focus on developments related to "the region's military escalation and efforts to de-escalate tensions," read the statement.
Pakistan’s foreign minister told Reuters on Thursday that “indirect talks” between the United States and Iran were taking place through messages relayed by Islamabad, with other states, including Turkey and Egypt, also supporting mediation efforts.
Iran had been weighing a 15-point peace proposal from US President Donald Trump, delivered by its neighbour Pakistan, which has emerged as an intermediary channel between the two sides.
Sources and reports indicate that Trump’s proposal included demands ranging from dismantling Iran’s nuclear program and curbing its missile development to effectively ceding control of the Strait of Hormuz.
A senior Iranian official told Reuters on Thursday that officials had reviewed the plan and concluded it served only American and Israeli interests, though the official stressed that diplomatic efforts were not yet exhausted.
On Friday, a senior Iranian official told Reuters that Tehran had not yet decided whether to respond to the American proposal in light of attacks on its industrial and nuclear infrastructure.
A decision, the official said, was expected either Friday or Saturday.
According to Reuters, Iran is demanding guarantees against future military action, compensation for losses, and formal control of the Strait of Hormuz, Iranian sources say.
Iran also told intermediaries that Lebanon must be included in any ceasefire deal, regional sources said.
Trump urged Iran on Thursday to engage “seriously” in negotiations, before “it is too late.”
Iranian Foreign Minister Abbas Araghchi said on Wednesday that Tehran had no intention of having talks with the US.
He added that an exchange of messages between the two countries through mediators “does not mean negotiations with the US,” Reuters reported.
The war, which has raged for nearly four weeks, has seen US and Israeli forces continue their attacks on Iranian industrial and nuclear infrastructure.
Iran has retaliated against US and Israeli strikes by hitting Israel and US bases; it has also struck Gulf states and blocked Middle East fuel exports via the Strait of Hormuz.
As a result, shipping has been massively disrupted, sending crude oil prices up nearly 40 percent and causing a spike of nearly 67 percent in shipments of liquefied natural gas to Asia.
Prices of nitrogen-based fertilizers, critical to food production, have risen by nearly 50 percent.
