Iranian President Masoud Pezeshkian has indicated his country is prepared to reciprocate if Washington honours the terms of a collapsed peace agreement signed in June, as he arrived in Bishkek for talks with Russian President Vladimir Putin.

Speaking on Tuesday ahead of the Shanghai Cooperation Organisation summit in the Kyrgyz capital, Pezeshkian said Tehran would “immediately take reciprocal action” should the United States return to its obligations under the memorandum of understanding.

The June agreement was designed to halt hostilities between the two nations that erupted in late February following American and Israeli strikes on Iran which killed former supreme leader Ayatollah Ali Khamenei. The deal, intended as a foundation for comprehensive peace negotiations, broke down amid mutual accusations of violations.

The Strait of Hormuz has emerged as a central flashpoint in the standoff. Iran maintains its blockade of the strategic shipping channel whilst asserting it would reopen the waterway if Washington fulfils its commitments under the June accord. The two sides resumed exchanges of fire on Monday after more than four weeks of reduced tensions.

Iranian Foreign Minister Abbas Araghchi echoed the president’s position, calling on the US to “return to its commitments and to what their president signed”.

“In that case, everything can be put back on the right track,” Araghchi said on Monday.

The SCO summit, promoted by Moscow and Beijing as a counterweight to Western influence, has drawn leaders from Turkey, India and Pakistan alongside the organisation’s ten member states. It now includes 15 dialogue partners – among them Turkey, Saudi Arabia and Qatar – plus observers Afghanistan and Mongolia.

Putin held discussions with Chinese President Xi Jinping on Monday, with both leaders highlighting strengthening bilateral relations. Xi described Russia-China ties as “more solid” with brighter prospects ahead, whilst Putin noted cooperation was “successfully developing on all fronts”.

The summit unfolds four and a half years into Russia’s invasion of Ukraine and six months into the conflict between Washington and Tehran. Moscow’s economy has grown increasingly reliant on Beijing since the Ukraine offensive began, whilst Russia has also expanded military and economic partnerships with Iran.

US President Donald Trump has cautioned Moscow and Beijing against providing weapons to Iran.
