The QW-2 Vanguard 2 is a Chinese all-aspect man-portable infrared guided surface to air missile. It isn't clear when the missile first entered service, but it is likely to have been between 1998 and 2002. 
The QianWei 2 (or Vanguard 2 in its export name) is the third-generation shoulder-launched, all-aspect IR-homing, 'fire-and-forget' surface-to-air missile developed by Shenyang-based CASIC 119 Factory (Shenyang Hangtian Xinle Ltd). The QW-2 was first revealed during the 1998 Farnborough Air Show. The missile and launcher of the QW-2 bear strong resemblance to those of the Russian 9K310 Igla-1 (NATO codename: SA-16 Gimlet), and the two missile systems are believed to be comparable in performance.
Compared to the QianWei 1, the minimum operating altitude of the QianWei 2 has been reduced from 30m to 10m; the operating range has been increased from 5 km to 6 km; and the missile’s reaction time has been reduced to below 5 seconds. The QianWei 2 features a newly developed dual-band passive IR seeker with strong resistance to heat flares dispensed by the target and solar/ground heat, thus improving the missile’s performance in day/night, all-weather conditions.
