Apparently in response to recent Indian tests of longer range missiles,
China has moved over a dozen of its DF-21 IRBMs to Yunnan Province (which
borders Myanmar, and puts most of eastern and northern India within range). The
DF-21 has a range of 1800 kilometers and a 300 kiloton warhead. China has over
fifty of them. Previously, most DF-21s were aimed at Russia and Japan.
