MOSCOW, November 5. /TASS/. Syria and almost all Middle East countries receiving Russian armaments pay for arms supplies in full and on time, state weapons exporter Rosoboronexport CEO Anatoly Isaikin said on Thursday.

"Naturally, we’re offering different payment plans, grace periods and loan mechanisms, depending on the economic condition of a country so that it can make long-term budget plans," he said in an interview with RT international news TV Channel.

"But almost all the countries, including Syria and other states in that unstable region, are paying the full cost within the time limits stipulated in the contracts," he added.

The Rosoboronexport head said he agreed with the statement that Russia’s military operation in Syria "is good testimony for Russian armaments."

"The efficiency of weapons in combat conditions is good testimony for this weaponry and, at the same time, inefficient use is bad testimony. So far, Russian armaments have good testimony precisely because they operate quite efficiently," he said.

Russian military operation in Syria

Russia started a military operation against the Islamic State terrorist group in the Syrian territory at the request of Syrian President Bashar al-Assad on September 30. The air group in Syria includes more than 50 warplanes, including Su-34 and Su-24M bombers; Su-25 assault aircraft; Su-30SM fighter jets as well as Mi-8 and Mi-24 helicopters.

The Russian pilots have made over 1,600 combat sorties and delivered air strikes at over 2,000 terrorist facilities since the military operation started.

Besides, overnight to October 7, the Caspian Flotilla ships delivered a massive strike at the IS objectives in Syria, using Kalibr NK shipborne cruise missiles.

The Russian authorities have said on many occasions that Russia’s military forces would not take part in any ground operation in Syria.
