中ソ国境紛争
China first obtained the RPG-2 85mm anti-tank RPG in the early 1950s, and began to build Chinese copies in 1956 under the designation Type 56. However, the rapid development of the new generation main battle tanks (MBTs) in the early 1960s posed new threats to the PLA, which was later proven in the 1969 Sino-Soviet border conflict. Because the Type 56 was unable to penetrate the armour of the new generation Soviet tanks such as the T-62, the PLA desperately needed a new individual anti-tank weapon to replace the aging Type 56.
