The one-day visit is part of efforts to strengthen relations between the two countries and "pursue mutual interests," according to foreign ministry spokesman Esmail Baghai.
Upon arrival, Araghchi met his Afghan counterpart Amir Khan Mutaki and is scheduled to sit at the table later with Deputy Prime Minister for Economic Affairs Abdul Ghani Baradar, state television reported.
The discussions will focus on border security, strengthening political ties and expanding economic relations, it added.
In recent years, tensions between Iran and Afghanistan have intensified over water rights and the construction of dams on the Helmand and Harirud rivers.
Iran shares a border with Afghanistan that is more than 900 km long, and the Islamic Republic hosts one of the world's largest refugee contingents, mostly Afghans who fled their country during two decades of war.
The flow of Afghan migrants has increased since the Taliban took power in August 2021 following the withdrawal of US forces.
In September, local media in Iran announced the construction of a wall along more than 10 km of the eastern border with Afghanistan, the main entry point for immigrants.
Officials said at the time that additional methods to fortify the border included barbed wire and water-filled ditches to counter "smuggling of fuel and goods, especially drugs" and to prevent "illegal immigration."
In December, Iran's ambassador to the UN, Amir Saeed Irawani, said that "over six million Afghans have sought refuge in Iran."
Iran has had an active diplomatic presence in Afghanistan for many years, but has yet to formally recognise the Taliban government since taking over the country.
Several Iranian delegations have visited Afghanistan over the years, including a parliamentary delegation in August 2023 to discuss water rights. | BGNES
