[As the mediate East Eye portal states](https://www.middleesteye.net/news/iran-receives-chinese-surface-air-missile-batteries-after-israel-casefire-say-sources), citing anonymous officials, the U.S. are aware of Chinese support for the Tehran authorities to strengthen its air defence. However, there is no detailed information on the scale of the project. Following the Israeli attacks on Iran, flights of Chinese transport aircraft (Boeing 747 Cargo) were reported disappearing from radar over Iran. However, there is no detailed information on the cargo. As MEE adds, it was in the late 1980s. Iran received HY-2 Silkworm maneuvering missiles from China via North Korea. In 2010, there was information that he was to receive HQ9 anti-aircraft missiles from Beijing.
