Iran's Terms for Ending S-300 Lawsuit Unclear

Iran is prepared to withdraw a lawsuit over Moscow's non-delivery of the S-300 air defense systems to Tehran, the Russian presidential aide on military-technical cooperation said Thursday.

MOSCOW (Sputnik) — Iran has already prepared all necessary documents to withdraw a lawsuit over Moscow's non-delivery of the S-300 air defense systems to Tehran, but the terms of such withdrawal are not clear, the Russian presidential aide on military-technical cooperation said Thursday.

"The Iranian side has prepared all the documents, sent them to Paris [where International Court of Arbitration is located], everything else is legal proceedings. The terms of withdrawal are not clear yet," Vladimir Kozhin told reporters, commenting on the timing of the complaint's withdrawal.

In 2007, Moscow and Tehran signed a $900-million deal for the delivery of five S-300 missile systems to Iran. In 2010, Russia suspended the contract, citing a UN Security Council resolution that placed an arms embargo on Tehran until it proved the peaceful nature of its nuclear project. Tehran filed a lawsuit against Moscow over the incident to the International Court of Arbitration.

In 2015, Moscow annulled the S-300 delivery ban, after Iran and six world powers, including Russia, reached a framework nuclear deal to lift the anti-Tehran sanctions in exchange for guarantees of the peaceful nature of its nuclear activities.

On April 11, the Iranian Foreign Ministry announced that Russia had made the first contracted delivery of the S-300 systems as scheduled.
