First Vice President Eshaq Jahangiri renewed the Islamic Republic of Iran's support for security and stability in Afghanistan, IRNA reported.
'The security and stability of Afghanistan is highly important for the Islamic Republic of Iran and Afghanistan's security is tantamount to our security,' Jahangiri said after his meeting with Afghanistan's Chief Executive Abdullah Abdullah in Tehran on Monday.
He underlined Iran's sensitivity toward Afghan security, and said, 'Fighting against extremism and terrorism plays an important role in this regards.
'Afghanistan and Iran share many commonalities and the two countries' relations in the field of regional cooperation,' he added.
He said that the Iranian and Afghan officials have held good and positive meetings, and said, 'During these meetings the two sides presented positive and constructive points.'
Iran is one of the most important donors to Afghanistan, which has kept its promises to help to the reconstruction of the war-ravaged country.
Iran has built several roads, power transmission lines, border stations and many other infrastructure projects to better link the two nations.
Iran has also contributed more than $50mln annually to Afghan anti-narcotics efforts during the last five years.
Tehran has repeatedly called for a withdrawal of the US-led foreign troops from Afghanistan, stressing that establishment of peace and security in the war-ravaged country is possible only through cooperation among the regional states.
