(CNN) -- Iran has designed an air defense system that has the same capabilities as a sophisticated Russian-made system, Iran's Press TV reported.
Russia announced in September that it was blocking weapons sales to Iran because of U.N. Security Council sanctions that banned export of armored vehicles, military aircraft, helicopters and ships.
Because of the sanctions, Moscow canceled shipment of its S-300 antiaircraft missile system to Iran.
"We have developed the system by upgrading systems like S-200 and we have tested it successfully using all our potential and experience in the Islamic Revolution Guards Corps (IRGC), the Army and the Defense Ministry," Brig. Gen. Mohammad Hassan Mansourian told Press TV on Wednesday.
The details of Iran's long-range missile defense system will be unveiled soon, Mansourian said.
Iran's announcement comes as Russian President Dmitry Medvedev is scheduled to meet Thursday with Iranian President Mahmoud Ahmadinejad to discuss Tehran's nuclear program on the sidelines of the Caspian summit in Baku, Azerbaijan.
Medvedev prohibited the sale of S-300 systems to Iran, citing the sanctions that were imposed in June over Tehran's nuclear program. The United States has said the nuclear program is military in nature; Tehran has insisted that it is intended solely for peaceful energy purposes.
Iran has said that the missile system was not covered by the sanctions.
