Turkey's Foreign Minister is seeking to assure neighbors that an arms deal with the United States would not be motivated by national security concerns, but rather as part of an effort by the country to update its defense systems.

The Obama administration announced Thursday that it would possibly sell $7.8 billion worth of Patriot PAC-3 antimissile batteries and related gear to Turkey, Reuters reported.

Turkey is the only NATO ally that shares a border with Iran. Turkey has not publicly confirmed the arms deal.

Turkey has good relations with Iran. It also shares its border with Georgia, Bulgaria, Greece, Iraq and Syria.
