Iran has announced special trade and maritime concessions for China and Russia in the Strait of Hormuz, while senior officials intensified criticism of the United States, accusing President Donald Trump of undermining diplomatic efforts.

Speaking to reporters in Tehran, Ibrahim Azizi, chairman of the Iranian parliament’s National Security Committee, said Tehran had decided to provide special facilities to Chinese and Russian vessels transiting the strategic waterway.

Azizi said the decision was made in light of the current regional situation and reflected Iran’s commitment to strengthening cooperation with its key partners. He added that Tehran would continue prioritising cooperation with friendly countries to safeguard mutual economic and commercial interests.

Referring to recent consultations between Pakistan and Iran, Azizi described the diplomatic engagements as important and constructive.

He also dismissed reports suggesting that Iran had discussed transferring enriched uranium to another country during ongoing international negotiations.

Azizi said the issue had not been raised in any talks or messages exchanged with the United States and reiterated that Iran would not compromise on its nuclear rights.

Meanwhile, Mohsen Rezaei, a senior adviser to Iran’s Supreme Leader and former commander of the Islamic Revolutionary Guard Corps (IRGC), accused Trump of abandoning diplomacy in favour of confrontation.

In a statement posted on X, Rezaei said the US president was “betraying diplomacy for the third time” and argued that Washington’s continued maritime blockade and what he described as excessive demands in negotiations demonstrated a lack of commitment to a peaceful settlement.

He claimed the United States was pursuing objectives beyond diplomacy and questioned Washington’s intentions in ongoing backchannel contacts.

Rezaei previously warned that Iran would either break the blockade through negotiations or take direct action if talks failed. He also maintained that the United States had no alternative but to negotiate, warning that prolonging the conflict would have serious consequences.

The remarks come as intermittent talks continue between Tehran and Washington aimed at securing a permanent end to hostilities following months of heightened tensions in the region.
