The People's Republic of China was approached by Iraq in the early 1980s to develop a copy of the ZSU-57-2 system and a few examples were delivered to the PRC for reverse-engineering. To meet Iraq's production order, NORINCO attempted to manufacture a copy with the improved amphibious chassis of the Type 69-II tank. Several Type 80 SPAAGs were tested and accepted into service by the People's Liberation Army (PLA) in small numbers. It was originally intended for the export market but didn't sell well. Greater success was achieved by Chinese-made proximity fuses which could be used to modernize the S-60 and S-68 ammunition.
