Pakistan Army Chief Field Marshal Asim Munir has arrived in Tehran leading a high-level delegation as diplomatic efforts intensify to sustain the fragile US-Iran ceasefire.

Munir is expected to convey a fresh message from Washington aimed at reviving stalled negotiations and extending the temporary truce, foreign media reports said. The visit marks a significant escalation of Pakistan’s mediation role, with the army chief — rather than civilian diplomats — travelling directly to the Iranian capital.

The development comes days after talks held in Islamabad failed to reach a final agreement, despite both sides signalling willingness to continue discussions. Key sticking points remain Iran’s nuclear programme, regional security concerns, and the future of the Strait of Hormuz.

Pakistan has emerged as a key intermediary in the conflict, having previously helped broker the two-week ceasefire between the US and Iran earlier this month. The military dimension of Munir’s visit underscores the seriousness of the diplomatic push — Iran’s FM Baghaei recently signalled flexibility on enrichment levels, offering the first concrete opening for a potential nuclear deal compromise.

For Sri Lanka, the outcome of these talks directly affects the country’s fuel supply outlook, with oil prices remaining volatile amid Hormuz uncertainty. A breakdown in negotiations could push prices back above the $100 threshold reached during the active blockade period.
