Iran is unlikely to accept zero uranium enrichment and full dismantlement of its nuclear program. Iranian Foreign Affairs Minister Abbas Araghchi stated on April 16 that uranium enrichment is a “real and undeniable right” and “not subject to negotiation.”[1] Araghchi stated that “contradictory” US positions do not help the negotiations and emphasized that “Iran must hear Washington's real stance” to assess whether a framework agreement is possible. Araghchi likely referred to recent remarks by US Special Envoy to the Middle East Steve Witkoff regarding “zero uranium enrichment,” in which Witkoff originally said Iran could enrich uranium to 3.67 percent before clarifying that any nuclear deal must “stop and eliminate” Iranian nuclear enrichment.[2] Iranian officials have consistently rejected the concept of zero uranium enrichment and stated that Iran may reduce enrichment to Joint Comprehensive Plan of Action (JCPOA) levels.[3] Iranian Expediency Discernment Council member and former Islamic Revolutionary Guards Corps (IRGC) Commander Mohsen Rezaei separately stated on X on April 16 that US statements reflect ”confusion and disarray” within the Trump administration and reinforce Iranian distrust caused by the U S withdrawal from the JCPOA in 2018.[4] Rezaei’s remarks align with Iranian Supreme Leader Ali Khamenei’s guidance in his April 15 speech. Khamenei said Iran must “proceed carefully” in the US-Iran talks and signaled deep skepticism toward the United States while supporting negotiations to mitigate pressure and preserve regime stability.[5] Khamenei will likely remain skeptical of any agreement with the Trump administration, given Trump's decision to withdraw from the JCPOA.[6]
Senior Iranian officials appear increasingly concerned about a potential US or Israeli strike on Iran. Khatam ol Anbia Air Defense Headquarters Commander Brigadier General Alireza Sabahi Fard visited Fordow Air Defense Group in Qom Province on April 16 to evaluate the unit's operational readiness.[7] The air defense site, also known as Hazrat-e Masoumeh Air Defense Group, is located approximately 16 km east of the Fordow Fuel Enrichment Plant (FFEP).[8] Fordow is a highly fortified underground uranium enrichment facility built into a mountain and reportedly designed to withstand military strikes, making it one of Iran's most secure nuclear sites.[9] Iran previously conducted air defense exercises near the Fordow nuclear facility in January 2025.[10] Sabahi Fard’s visit marks the fourth stop in the ongoing Iranian air defense inspections that began on April 4.[11]
The Houthis, supported by Iran, have long used communications equipment to maintain internal control and oppress the Yemeni population.[40] The Iranian regime has experience building a police and surveillance state and likely seeks to share this expertise to enhance the already strong Houthi control over Yemen's telecommunications sector and advance Houthi efforts to build a similarly strong authoritarian state.
The Iranian rial appreciated from 890,000 rials to one US dollar on April 15 to 875,000 rials to one US dollar on April 16.[73]

Iran Update, April 17, 2025
Senior Iranian political and military officials, including Supreme Leader Ali Khamenei, met with Saudi Defense Minister Khalid bin Salman in Tehran on April 17. Saudi Arabia may seek to reassure Iran about its positions on a potential strike on Iran and a potential ground offensive against the Houthis in Yemen.[1] Salman’s visit to Iran follows recent statements by senior Iranian officials threatening to attack any base “used by Americans” in a potential strike on Iran.[2] These threats likely seek to discourage US partners in the Middle East, including Saudi Arabia, from supporting an attack on Iran. Iran previously threatened in October 2024 that it would attack Saudi energy infrastructure if Saudi Arabia supported an Israeli attack on Iran.[3] Salman may have sought to reassure Iranian officials that Saudi Arabia would not support an attack on Iran.
Salman, accompanied by Saudi Ambassador to Yemen Mohammed al Jaber, may have also sought to reassure Iran that Saudi Arabia would not support a ground offensive against the Houthis in Yemen.[4] Salman’s visit to Iran follows recent reports that some Gulf countries and anti-Houthi factions in Yemen are exploring the possibility of a Yemeni government ground offensive against the Houthis.[5] Unspecified Saudi officials told Western media on April 14 that Saudi Arabia would not participate in a ground offensive.[6] Iran views the Houthis as an integral part of the Axis of Resistance, particularly since Israel has significantly degraded other key members of the Axis of Resistance, including Hezbollah and Hamas.[7]
A Chinese government-linked satellite company provided intelligence to the Houthis, according to US officials speaking to the Financial Times on April 17.[8] This intelligence could support Houthi attacks against US vessels and commercial shipping, which demonstrates how the Houthis are continuing to cooperate with US adversaries to disrupt global trade. The US government raised concerns to the Chinese government about Chang Guang Satellite Technology Co., Ltd. (CGSTL) providing satellite intelligence to the Houthis.[9] The Chinese government reportedly ignored these concerns. CGSTL has ties to the Chinese military through China’s military-civilian “fusion” program, which aims to integrate private sector work with military research and development, according to research done by a Washington-based security consulting firm.[10] CGSTL’s provision of satellite intelligence to the Houthis is part of ongoing Chinese, Russian, and Iranian support to the Houthis. Houthi-owned military communications and domestic surveillance companies have reportedly imported Chinese-made communications equipment.[11] Iran and Russia have provided targeting intelligence to the Houthis, which aids Houthi attacks on international shipping.[12] The Yemeni coast guard and Omani customs have previously seized shipments of Chinese-made military equipment to the Houthis, such as hydrogen fuel cells for powering missiles and drone propellers.[13] The Houthis reportedly told China and Russia in March 2024 that the Houthis would not target Chinese and Russian-flagged vessels transiting the Red Sea, according to several sources with knowledge on Houthi leadership discussions.
International Atomic Energy Agency (IAEA) Director General Rafael Grossi met with senior Iranian officials in Tehran on April 16 and 17 to discuss the Iranian nuclear program and the US-Iran nuclear talks.[77] Grossi stated that the IAEA is in contact with US negotiators to discuss how the agency can serve as a bridge between Iran and the United States and help achieve a positive outcome in the talks.[78] Iranian Foreign Affairs Minister Abbas Araghchi stated that the IAEA can play an important role in peacefully resolving the Iranian nuclear issue.[79] Araghchi called on the IAEA “to take a clear stance” against recent threats to the Iranian nuclear program.[80] Grossi told French media before traveling to Iran on April 16 that Iran is “not far” from possessing nuclear weapons.[81]
Iranian Foreign Affairs Minister Abbas Araghchi met with Russian President Vladimir Putin in Moscow on April 17 and delivered a message from Supreme Leader Ali Khamenei to Putin.[82] Araghchi stated that Khamenei’s message addressed important regional and international developments as well as bilateral issues.[83] Araghchi emphasized that Russo-Iranian relations are stronger and more respectful than ever before and noted that the recently-signed Comprehensive Strategic Partnership Agreement elevated the relationship between Iran and Russia to a strategic level.[84] Araghchi emphasized the importance of close coordination with Russia and China on the Iranian nuclear issue.[85] Iran, China, and Russia issued a joint statement on March 14 that condemned US sanctions on Iran and defended the Iranian nuclear program “as peaceful.”[86]
