China is proceeding with the planned purchase of 4-8 battalions of S-300 systems from Russia, reports Jane’s. The S-300 (SA-10/20) purchase confirms an earlier report noted here over a month ago. It is unclear whether the purchase would be the S-300PMU1 or the more advanced S-300PMU2, which has a longer range missile and better radar.

The S-300 anti-air defence system is a mobile air defence system similiar in capability to the American Patriot Missile.
