40 other fuel tankers are to reach Afghanistan from Iran on Wednesday, ISNA reported.
Afghan Ministers of Economy, Finance, Industries and Trade are to visit Iran later this week to settle fuel problem following a meeting between Iranian ambassador to Afghanistan
Fada Hossein-Maleki and President Hamid Karzai in Kabul Tuesday evening initiated by Afghan government.
Iranian officials have said that process of fuel transit to Afghanistan depends on Kabul needs.
Iran is a fuel transit route to Afghanistan from Iraq and the UAE. But the amount of demanded fuel has been raised sharply which raised doubts for Iran.
Iran insists that plan of raising fuel swap to Afghanistan seeks meeting needs of North Atlantic Treaty Organization (NATO) forces.
Iranian embassy in Kabul reported on Tuesday some 399,764 tons of fuel were transferred to Afghanistan via the country over last 10 months.
The embassy issued a statement to make the public mind aware of the facts and confront some smear campaigns against the Islamic Republic over last few days.
The statement said that 929 tankers carrying 71, 501 tons of fuel were moved to Afghanistan from December 22 to January 15 after Afghan First Vice President Mohammad Qasim Fahim's trip to Tehran.
The statement said the delay in fuel transit came due to lack of any formal declaration to Iran by Afghan Ministry of Trades and Industries over the required level of fuel.
"Fuel transit will be carried out based on mutual agreements in case of Afghan government's interest," the statement read.
