Signature of Russia-Iran S-300 contract delayed as parties still bargaining about price

Russia and Iran will sign a contract for S-300 surface-to-air missile systems as soon as they fully agree upon the transaction's price parameters, a source with knowledge of the situation told Interfax-AVN on August 26.

"The decision on Iran's purchase of S-300s has been made in principle. It remains only to agree upon the contract's value," the source said.

This is precisely the reason why the contract will not be signed at the MAKS 2015 international air show currently under way outside Moscow, contrary to what was planned before, he said.

"Nevertheless, the contract's signature is a matter of several weeks or perhaps even days," the source said.
