"Standing up against the crimes and barbarism of the Zionist regime in Gaza and the West's support for this bloodshed is a collective duty," Iran's Supreme Leader Ali Khamenei told a group of Red Crescent Society rescue workers on Monday.
"Today, the world is being run by these human-like beasts, and the Islamic Republic considers it its duty to stand against their savagery and bloodshed," he added, according to a readout of his remarks published by his website on Wednesday.
The remarks were among the sharpest since talks between the United States and Iran began last month, and were published after US President Donald Trump lambasted Tehran's foreign and domestic policy in a Riyadh speech on Tuesday.
"It is this sense of duty that has driven enemies like the Westerners to confront the Islamic Republic, because if we stopped opposing their barbarity, they would have no enmity with us."
"The main issue of the Western bullies as the Islamic Republic's rejection of their false civilization and said: Falsehood is doomed to decline and destruction," he added.
President Donald Trump’s high-profile trip to Saudi Arabia has drawn renewed attention to the often fraught relationship between the Middle East’s main heavyweights: Sunni Saudi Arabia and its Shi'ite rival Iran.
While Trump’s trip may not have fundamentally shifted the course of Iran-Saudi relations, it underlines how central their evolving dynamic remains to the region’s future especially as nuclear negotiations between Tehran and Washington continue to unfold.
On Wednesday, Saudi Foreign Minister Faisal bin Farhan underscored the importance of the US-Iran nuclear talks, saying the kingdom fully supports them and hopes for a positive outcome.
Iran's Foreign Minister Abbas Araghchi, in turn, visited Saudi Arabia on Saturday before the fourth round of talks with the US to brief them on the latest developments. He had said last Wednesday that Tehran seeks regional consensus on the talks and any potential deal.
Rivalry and diplomatic tension
The two regional powerhouses have long been vying for influence across the Middle East. Their rivalry has played out in a series of proxy conflicts over the past two decades — from Iraq and Bahrain to Syria and Yemen — where the two sides supported opposing factions.
One of the most acute flashpoints came in 2015, when Riyadh launched a military campaign in Yemen against the Iran-backed Houthi rebels. Although Tehran has always denied direct military involvement, it has been widely accused of supplying weapons and political support.
Relations deteriorated further in 2016 after Saudi Arabia executed prominent Shia cleric Sheikh Nimr al-Nimr. The move sparked violent protests and attacks on Saudi diplomatic missions in Tehran and Mashhad, prompting Riyadh to sever diplomatic ties. This marked one of the lowest points in bilateral relations in decades.
Aramco attack
A September 2019 drone and missile attack on the state-owned Saudi Aramco oil hub that disrupted about five percent of global oil supply marked one of the most significant escalations in the Tehran-Riyadh relations in recent years.
Although the Houthis claimed responsibility and Iran denied any involvement, the sophistication of the weaponry used in the attacks led not only Riyadh and Washington but also European powers to directly blame Iran.
Riyadh appeared to change tack away from years of direct and indirect confrontation with Tehran gradually after the assault on its economic lifeline, paving the way for detente.
Signs of a diplomatic thaw
The recent years have seen a cautious thaw in relations. After the initiation of direct talks in April 2021, a breakthrough came in 2023 with Chinese-brokered talks that led to the restoration of diplomatic relations. Since then, both sides have tentatively explored cooperation and re-engagement, even as deep-seated mistrust remains.
From early 2025 to now, Iranian and Saudi officials have held multiple high-level meetings.
Saudi Arabia has reportedly also positioned itself as a backchannel mediator between Iran and the United States in nuclear talks in the past few months.
Recent diplomatic engagements
Diplomatic momentum picked up pace in October 2024, when the newly appointed Araghchi visited Riyadh and met with Crown Prince Mohammed bin Salman and foreign minister amid growing the growing Gaza conflict.
A few weeks later, the Saudi Crown Prince’s call to Israel to cease all hostile actions on Iranian territory surprised many.
Further momentum came in April when Saudi Defense Minister Prince Khalid bin Salman made a rare visit to Tehran, delivering a letter from King Salman bin Abdulaziz to Iran’s Supreme Leader Ayatollah Ali Khamenei.
The timing — just days before another round of Tehran-Washington nuclear talks — underscored Saudi Arabia’s possible diplomatic involvement.
Araghchi returned to Riyadh on May 10, ahead of the fourth and most recent round of nuclear talks in Doha. Iranian media reported that he delivered a response to the Saudi king’s letter, continuing what appeared to be an unprecedented backchannel of direct communication.
Toward a regional nuclear consortium?
During Trump’s meetings in Riyadh, the possibility of a civil nuclear agreement between the US and Saudi Arabia was reportedly discussed.
In one of the most intriguing diplomatic moves of 2025, Iran is believed to have proposed the creation of a regional uranium enrichment consortium with Saudi Arabia, the United Arab Emirates, and the United States.
The initiative, not officially confirmed by either Tehran or Riyadh so far, may have been pitched as a confidence-building measure designed to reassure the West about Iran’s nuclear intentions while embedding regional powers and the United States in a shared framework.
Saudi Arabia, long intent on developing its own civilian nuclear capabilities, may view such a proposal as an opportunity to gain influence over regional nuclear policy while maintaining checks on Iran’s activities. However, significant technical and political obstacles would need to be overcome.
Hossein Salami, the commander of the Islamic Revolutionary Guard Corps (IRGC), characterize current events as the “era of historic battle between Islamic forces and global satanic powers".
Salami further accused President Donald Trump of trying to "make the Iranian nation lose hope in the Islamic Revolution and the system."
His comments came a day after Trump's sharp criticism of Iran's leadership in a lengthy speech in Saudi Arabia.
"Iran's decades of neglect and mismanagement have left the country plagued by rolling blackouts lasting for hours a day ... While your skill has turned dry deserts into fertile farmland, Iran's leaders have managed to turn green farmland into dry deserts as their corrupt water mafia ... causes droughts and empty river beds. They get rich," the US president said.
In his Wednesday remarks, Salami also said that "the Iranian nation is invincible and cannot be humiliated on the battlefield, nor will it be defeated in the field of diplomacy."
Iran’s Expediency Council has conditionally approved the country’s accession to the Palermo Convention, one of the two key legislative items tied to the Financial Action Task Force (FATF) standards aimed at addressing money laundering and terrorism financing.
The move could ease Iran’s exit from the international money laundering blacklist and restore access to global banking should Western sanctions against it be lifted.
In a brief statement, the council's spokesman Mohsen Dehnavi announced it had agreed to join the UN convention against transnational organized crime, “within the framework of the Constitution and domestic laws.”
The decision marks a cautious step toward meeting FATF requirements but falls short of full endorsement.
The council also confirmed that discussions on the related Countering the Financing of Terrorism (CFT) bill will continue in upcoming sessions.
The move comes amid strong opposition from over 150 hardline lawmakers, who last month urged the Council to reject both conventions.
In a letter to Expediency Council chairman Sadeq Amoli Larijani, they argued that any approval—conditional or not—should wait until the risk of the UN “snapback” sanctions mechanism is entirely eliminated.
The snapback mechanism, which allows for the automatic reimposition of UN sanctions under the 2015 nuclear deal, is set to expire in October 2025 unless triggered by a signatory.
While Larijani recently hinted that conditional approval might be viable, conservative MPs have warned that even limited compliance could make Iran vulnerable to external pressure and economic penalties.
The FATF has kept Iran on its blacklist due to its failure to adopt international standards on money laundering and terror financing.
"We certainly discussed Iran, where it's been really an interesting situation. I have a feeling it's going to work out," US President Donald Trump said at a ceremony in Doha alongside Qatar's Emir Sheikh Tamim bin Hamad Al-Thani.
"It's got to work out, one way or the other. We know it's going to work out, but you were of great help," he added.
