The Iranian government stressed that any decisions on potential nuclear talks would be made within the framework of the Supreme National Security Council, in a nod to the conservative establishment.
The visit, the first by an Iranian foreign minister since the Taliban's 2021 return to power, focused on trade relations, the return of Afghan migrants, and Iran’s contentious water rights from the Helmand River.
Esmail Baghaei, spokesperson for Iran’s Ministry of Foreign Affairs, wrote in a message on X: "This visit could be a turning point in leveraging the numerous ties between the two nations to secure the mutual interests of both countries."
On Sunday, Araghchi met with Mullah Mohammad Hassan Akhund, the Taliban's acting prime minister, and Amir Khan Muttaqi, the acting foreign minister.
Water rights dominate discussions
One key issue discussed was Iran's longstanding dispute over water rights from the Helmand River, vital for Iran’s drought-stricken Sistan-Baluchestan province which relies on the Helmand River to sustain its wetlands, including the Hamoun Lake.
Iranian officials emphasized that Afghanistan must honor its obligations under the 1973 Helmand Water Treaty.
Iranian media reported on Sunday that Taliban representatives assured Araghchi they were working to ensure water flowed to Iran without waste.
There have been escalating tensions over the construction of dams on transboundary rivers, which have significantly reduced water flow to Iran’s drought-stricken eastern provinces.
The recently completed Pashdan Dam on the Harirud River in Afghanistan has become the latest focal point in the longstanding dispute.
Afghanistan’s water management projects have attracted foreign investment, adding complexity to the issue.
Countries such as China and Turkey are leveraging Afghanistan's water sector to establish strategic footholds in the region. The Pashdan Dam itself was built with assistance from an Azerbaijani firm, highlighting the international dimensions of the dispute.
The issue now dates back decades. In 1999, the Taliban completely halted the flow of the Helmand River, causing significant environmental and economic hardship for Iran.
Although a 1973 treaty guarantees Iran a share of the river's water, enforcement has been inconsistent, often leaving Iran's eastern provinces in a state of crisis.
Migration challenges and security concerns
Araghchi’s visit also addressed the repatriation of undocumented Afghan migrants. Iran, which hosts millions of Afghans, has ramped up deportations, with nearly three million undocumented individuals sent back in the past three years, according to government figures.
The discussions come against a backdrop of heightened border tensions and security concerns for both sides. Amir Khan Muttaqi called the visit “an opportunity to deepen brotherly ties between two neighboring Muslim nations that have shared both grief and joy."
Iran shares over 900 kilometers (560 miles) of its border with Afghanistan and hosts one of the largest refugee populations globally, predominantly Afghans who fled during more than two decades of war.
Afghanistan has historically seen a steady flow of migrants into Iran. However, following the Taliban's takeover of Afghanistan, this influx has surged, with millions crossing the border.
Some reports indicate that up to 10,000 Afghans have been entering Iran daily, pushing the Afghan population in the country to nearly 10 million.
Many Iranians have criticized the government for failing to secure the border, suspecting that it intends to use Afghan migrants as foot soldiers—both to suppress discontent within the domestic population and to deploy across the region to bolster its military allies and proxies, as documented by Human Rights Watch.
In December, Iran's ambassador to the United Nations, Amir Saeid Iravani, said that "over six million Afghans have sought refuge in Iran."
Economic prospects in focus
Trade featured prominently in Araghchi’s agenda, with a specialized Iranian delegation accompanying him, Afghanistan a key partner for Iran, with bilateral trade volumes reaching $3.2 billion last year.
Iran aims to increase this figure to $5 billion in two years, supported by infrastructure projects like the Khaf-Herat railway and the development of the Dogharoon trade zone.
"The economic relations between Iran and Afghanistan are at a very good level," Araghchi said during the meetings, expressing hope for their further enhancement.
Zakir Jalali, a senior Taliban foreign ministry official, hailed Araghchi’s visit as a “gateway to a new phase in relations.” Economic cooperation, Jalali noted, is essential for addressing mutual challenges and leveraging shared cultural and historical ties.
Iran has not officially recognized the Taliban as the legitimate government of Afghanistan, with countries such as the EU, US and UK still designating them as a terrorist organization.
However, Iran maintains a pragmatic approach. Following the Taliban's takeover of Afghanistan in August 2021, Iran kept its embassy in Kabul open and has continued to engage with Taliban officials.
After Zarif suggested the country was more open to international diplomacy under the new presidency, including with its archenemy the US, Mohammad Bagher Ghalibaf, Speaker of the Parliament, warned officials to tread carefully in their public statements to avoid emboldening adversaries.
Ghalibaf said that projecting a perception of weakness from Iran’s leadership could prompt “miscalculations by the incoming US administration and worsen economic pressures.”
Iran faces a serious economic crisis, expected to get worse if US President Donald Trump puts more sanctions pressure. As a result, debate is now raging in Tehran as Iran's Supreme Leader has not authorized any new negotiations.
Zarif, a former foreign minister and now Iran's Vice-President for Strategic Affairs, stirred controversy when he suggested in a Wednesday interview with CNN host Fareed Zakaria that if conservative politician Saeed Jalili had been elected president instead of Masoud Pezeshkian last July, a major war might have been underway in the region.
Zarif’s attempt to portray Iran as seeking de-escalation and potentially relaxing hijab laws backfired, drawing heavy criticism from both the Iranian public for denying pressure on women, and officials. A senior official called for his immediate arrest.
Hardliners have launched an online petition urging the IRGC Intelligence Organization to arrest Zarif immediately over his hijab remarks, which they claim amount to an effort for regime change. Nearly 55,000 people have signed the petition so far.
Ahmad Khatami, a senior Friday prayer leader, has also criticized the idea of US-Iran negotiations, describing them as “a tactic to counter the revolution.”
The conservative Kayhan newspaper and figures close to Supreme Leader Ali Khamenei amplified the critiques, with some calling for Zarif’s prosecution.
Conservatives Denounce Zarif’s Tone
Zarif’s acknowledgment that Iran no longer harshly enforces the hijab sparked particular outrage among hardliners. Mohammad Manan Raisi, a representative from Qom accused Zarif on Sunday of violating the country’s laws and disrespecting religious mandates.
“This individual has brazenly mocked God’s explicit command at an international forum,” Raisi said, referencing Zarif’s comment about unveiled women in Tehran and saying the government has relaxed hijab enforcement in Iran.
Raisi also criticized institutional inaction, saying that efforts to address Zarif’s remarks had stalled.
The Ham Mihan newspaper, however, defended Zarif’s remarks, saying that Fareed Zakaria's question was based on the premise that the presence or absence of moderates in the political structure of the Islamic Republic makes no difference, and Zarif sought to refute this notion.
The paper argued that Zarif’s engagement at Davos sought to portray Iran as a rational actor committed to international norms, despite significant internal and external challenges.
Domestic Debate on Negotiations
Citing European officials, Axios recently reported that Iran may be signaling openness to a new agreement distinct from the 2015 Joint Comprehensive Plan of Action (JCPOA). Despite this, opposition to dialogue with the US remains fierce among hardliners.
Fatemeh Mohajerani, the Government Spokeswoman speaking to ILNA, sought to assuage concerns about negotiations on Sunday, emphasizing that decisions on critical issues like the nuclear program are made within the Supreme National Security Council.
“We assure concerned individuals that decision-making in the country follows a completely rational and well-established process,” she said.
Zarif’s attempt to position Iran as a cooperative global player has drawn fire from conservatives who view his comments as signaling capitulation. Critics argue that such rhetoric undermines the nation’s revolutionary ideals, while supporters see it as a pragmatic effort to mitigate international isolation.
The remarks from the spokeswoman of the relatively moderate government appeared aimed at reassuring hardliners that any talks will be subject to strict oversight and not diverge from the priorities of Supreme Leader Ali Khamenei.
President Masoud Pezeshkian’s said earlier this month he was ready to engage in talks with the US administration of Donald Trump.
However, the move prompted questions within Iran about whether he had higher-level approval for such an initiative.
Government spokeswoman Fatemeh Mohajerani addressed domestic concerns, particularly from hardliners wary of negotiations with the West, emphasizing the established and controlled nature of the decision-making process.
"In important matters such as the nuclear issue, the matter is raised and reviewed in the Supreme National Security Council (SNSC), and the approvals of the council also specify what path must be followed for implementation," Mohajerani said in an interview with ILNA news agency on Sunday.
Mohajerani further urged against internal political disputes affecting foreign policy: "We should all be aware that foreign policy issues and national issues in general should not become an arena for factional and transnational disputes. We must proceed with consensus and agreement on foreign policy issues."
The SNSC is tasked by the Constitution to define national security and defense policies within the framework set by Khamenei.
The Supreme Leader appoints the SNSC secretary and holds final approval power over all SNSC decisions, placing him and the council at the center of Iran's foreign policy apparatus.
The SNSC formulates Iran's nuclear policy, subject to the Supreme Leader's ratification. The SNSC secretary also led nuclear negotiations until 2013, when the responsibility was assigned to the foreign ministry.
In recent weeks, several politicians and commentators in Iran have indicated that President Masoud Pezeshkian has received approval from the Supreme Leader and the Supreme National Security Council to initiate negotiations with the United States despite the two nations breaking ties in 1980.
However, none of the authorities have officially confirmed that they have authorized any such negotiations with the United States regarding Iran's nuclear program or other contentious issues.
Pezeshkian has tacitly conveyed Tehran's willingness to engage in talks with the US, but Khamenei’s hardline allies have strongly criticized both his remarks and those of other officials who advocate for talks.
Such discussions in Iran come as the International Atomic Energy Agency (IAEA) continues to express concerns about the level of access its inspectors have to Iranian nuclear facilities.
IAEA chief Rafael Grossi, speaking at the World Economic Forum in Davos last week, said, "We are not inspecting at the levels or at the places that we believe we should be inspecting.”
He also highlighted that Iran has accumulated approximately 200 kg of uranium enriched to up to 60% purity, a level dangerously close to weapons-grade.
While Grossi acknowledged the IAEA has no concrete evidence of a current Iranian nuclear weapons program, he reiterated that Tehran is not fully cooperating with the agency.
UN Secretary-General Antonio Guterres also addressed the issue at Davos, calling on Iran to definitively renounce nuclear weapons and improve relations with its regional adversaries and the United States.
"The most relevant question is Iran and relations between Iran, Israel and the United States," Guterres said. "Here my hope is that the Iranians understand that it is important to once and for all make it clear that they will renounce to have nuclear weapons, at the same time that they engage constructively with the other countries of the region."
