Iran will not enter into negotiations under pressure, threats or siege, President Masoud Pezeshkian said, according to Mehr News on Sunday. He criticised what he described as continued violations and coercive conduct by the United States during both ceasefire negotiations and their implementation.

Pezeshkian said Washington’s so-called maritime restrictions on Iran amounted to a clear breach of ceasefire understandings and were inconsistent with the United Nations Charter. Such measures, alongside what he called threatening rhetoric, had raised doubts about the US commitment to the diplomatic process.

Reaffirming Iran’s resolve to safeguard its national security, he warned that any renewed confrontation involving the United States and Israel could have serious consequences for both regional and global stability.

He also stressed that Iran remained committed to strengthening ties with neighbouring countries, including those along the southern shores of the Persian Gulf, based on good neighbourliness and mutual respect. He expressed hope that regional states would work collectively to promote peace and security free from external interference.

He made these remarks in a telephone call with Prime Minister Shehbaz Sharif that lasted 50 minutes, during which the two leaders discussed the regional situation and ongoing efforts to promote peace and stability in the region.

PM Shehbaz appreciated the participation of a high-level Iranian delegation in talks held in Islamabad on April 11–12, and welcomed Tehran’s decision to send a delegation led by Foreign Minister Abbas Araghchi, who held important meetings, including a two-hour session with him.

He further said his recent diplomatic outreach to world leaders had helped build a broader consensus in support of sustained dialogue aimed at achieving lasting peace in the region. He also expressed appreciation for discussions between the Iranian leadership and Field Marshal Syed Asim Munir during his recent visit to Tehran.

Reaffirming Pakistan’s commitment to regional peace, the prime minister said Islamabad would continue efforts to promote stability and security.

The Iranian president thanked PM Shehbaz, Field Marshal Munir and Deputy Prime Minister Ishaq Dar for their contribution to peace efforts, and expressed confidence that ties between Iran and Pakistan would continue to strengthen.

PM Shehbaz conveyed his regards to Iran’s Supreme Leader, Ayatollah Mojtaba Khamenei, and both leaders agreed to maintain close coordination.

On Saturday, Iranian foreign minister, after speaking only to Pakistani officials, departed for Muscat from Islamabad after describing his visit as “very fruitful”.

“Very fruitful visit to Pakistan, whose good offices and brotherly efforts to bring back peace to our region we very much value,” Araghchi said on X. “Shared Iran’s position concerning a workable framework to permanently end the war on Iran. Have yet to see if the US is truly serious about diplomacy,” it added.

Iranian media later reported that Araghchi had arrived in Muscat for talks with Omani officials on bilateral relations and regional developments, and is expected to return to Pakistan before travelling to Russia, according to IRNA News Agency.
