Tehran: Iran has laid out conditions for future oil exports to European countries after halting sales to Britain and France earlier this week.

Foreign Ministry spokesman Ramin Mehmanparast said on Tuesday that Iran seeks guarantees of payments, long term contracts and a ban on unilateral cancellation of contracts by buyers.

He says all these should be considered if Europe wants continued trade and oil relations.

Mehmanparast says Iran's conditions were conveyed in a meeting with ambassadors of six European countries in Tehran.

Tehran said on Monday it was considering extending the oil embargo to other European countries. The cutoffs to France and Britain were in retaliation for an EU embargo over

Tehran's controversial nuclear program that is to go into effect in July.
