Pakistani Deputy Prime Minister and Foreign Minister Ishaq Dar urged the United States and Iran to uphold their commitment to the ceasefire on Sunday.
The Islamabad Talks concluded without an agreement, pledging that Pakistan would continue to facilitate engagement and dialogue between the two sides "in the days to come."
Speaking at a brief press conference in Islamabad following the conclusion of the talks, Dar issued a direct call to both parties.
"It is imperative that the parties continue to uphold their commitment to ceasefire," Dar said.
"We hope that the two sides continue with the positive spirit to achieve durable peace and prosperity for the entire region and beyond," he added.
Dar also expressed gratitude to both delegations for their participation.
"On behalf of Pakistan, I would like to express gratitude to the two sides for appreciating Pakistan's efforts to help achieve the ceasefire and its mediatory role," he said.
Dar described the scope of Pakistan's role over the 24 hours.
"I, along with the Chief of Defence Forces and army chief Field Marshal Syed Asim Munir, helped mediate several rounds of intense and constructive negotiations between the two sides that continued over the last 24 hours and ended this morning," he said.
Dar made clear that Pakistan's role does not end with the Islamabad Talks.
"Pakistan has been and will continue to play its role to facilitate engagement and dialogue between the Islamic Republic of Iran and the United States of America in the days to come," he said.
He also thanked both Iran and the U.S. for responding to Prime Minister Shehbaz Sharif's call for an immediate ceasefire and for accepting Sharif's invitation to hold peace talks in Islamabad.
Dar's remarks came after Vance addressed reporters and departed Pakistan, having said the talks concluded without agreement after 21 hours of negotiations.
The U.S. delegation was led by Vance and included Special Envoys Steve Witkoff and Jared Kushner.
The Iranian delegation was led by Parliament Speaker Mohammad Bagher Ghalibaf.
