Iran’s chief negotiator and parliament speaker Mohammad Bagher Ghalibaf has said the United States failed to win Tehran’s trust during recent high-stakes talks, underscoring deep divisions that led to the collapse of negotiations between the two sides.

The remarks came after marathon discussions lasting nearly 21 hours ended without an agreement, despite what Iranian officials described as constructive engagement. Ghalibaf stated that while Iran entered the talks with “good faith” and forward-looking proposals, Washington ultimately did not succeed in building confidence with the Iranian delegation.

The failed negotiations, held in Islamabad, were aimed at easing tensions linked to Iran’s nuclear programme and broader regional conflict. However, key disagreements—particularly over Tehran’s refusal to abandon its nuclear ambitions and US demands seen as excessive—proved insurmountable.

Iranian officials have consistently maintained that a lack of trust in the United States remains a central obstacle to any agreement. They have pointed to past conflicts and what they describe as broken commitments by Washington as reasons for their cautious approach to diplomacy.

The collapse of the talks has heightened uncertainty in the region, with both sides signalling hardened positions even as they leave the door open for possible future dialogue. Analysts warn that continued mistrust could prolong the standoff, with implications for regional stability and global energy markets.

Despite the setback, diplomatic channels are not entirely closed, and there are indications that indirect engagement could continue. However, rebuilding trust between the two sides is likely to remain a significant challenge in any renewed negotiation efforts.
