Iran is known for producing a significant number of its own weapons but still relies on other countries for advanced military technology. Among its closest allies, China and Russia play a pivotal role in supplying Iran with weapons and military components. This relationship goes beyond mere transactions—encompassing technology sharing, mutual assistance, and joint production initiatives. Russia supplies Iran with advanced military hardware like aircraft and anti-aircraft missiles, while China primarily provides components and chemicals critical for weapon manufacturing.

The strategic partnership between Iran, Russia, and China is aimed at countering Western influence, particularly from the US and Israel, thus helping Iran strengthen its defense capabilities. This cooperation has not only enhanced Iran's military capabilities but has also solidified a united front against Western pressures. Iran's ability to acquire modern weaponry has been a crucial factor in maintaining its influence in the region and supporting its military operations.

The depth of the arms relationship between Russia and Iran has grown notably since the onset of the Ukraine war in 2022, highlighting Iran's importance as a military supplier to Russia. Tehran has supplied Moscow with thousands of Shahed-136 drones, which have been employed in various conflicts, reinforcing the military bond between the nations and indicating a significant shift in global military alliances as countries look to strengthen defense ties amidst geopolitical tensions.
