Kuwaiti Foreign Minister Sheikh Salem Abdullah Al Sabah has been invited to Tehran for an official visit to ease tensions over the offshore Durra gas field.
Iran, Kuwait and Saudi Arabia are locked in a dispute because all three countries claim a stake in the gas field.
Saudi Arabia and Kuwait say they have exclusive joint rights to the field, while Iran also claims a stake and says a Saudi-Kuwaiti agreement to develop it, signed last year, is illegal.
Sheikh Salem was given the invitation when he received Iran’s new ambassador, Mohammad Totonchi, according to a ministry statement.
The invitation comes as Saudi Arabia and Kuwait on Thursday said that they are the only states with rights to the natural resources in Durra gas field.
It said the countries “alone have full sovereign rights to exploit the wealth in that area”, the Saudi Foreign Ministry said.
