Speaking to reporters after a cabinet meeting here in Tehran on Wednesday, Vahidi said Iran relies on its own capabilities and has built up an invincible dam against enemies.
He pointed to the destabilizing role of the alien powers in the region, and said, "Iran is to help maintain security in the Middle East, relying on its own forces."
Yet, the minister reiterated the defensive nature of Iran's military forces and equipment, saying they serve peace and render service to the other regional countries.
Vahidi's comments came after Tehran unveiled a number of new home-made defense equipment.
Iran unveiled six major achievements of its defense industries on Tuesday. The six achievements included the fourth generation of Fateh 110 missile, Bonian 4 marine engine, Armita space test laboratory, Aras tactical vehicle, Vafa mortar-launcher, and Shahed navigation system.
Tehran launched an arms development program during the 1980-88 Iraqi imposed war on Iran to compensate for a US weapons embargo. Since 1992, Iran has produced its own tanks, armored personnel carriers, missiles and fighter planes.
Yet, Iranian officials have always stressed that the country's military and arms programs serve defensive purposes and should not be perceived as a threat to any other country.
