I was wondering why China didn't supply NVA with those...?
China received SA-75 Dvina “five van” (SA-2A) with V-750 1D (Guideline mod.0) in 1958-3+1*, and 1959-2 pieces (* means training system) only.
The Chinese 1D missile had severe limitations compared to the 11D supplied to Vietnam by the Soviets.
