Wonder if this is in addition to the reported 150,000 moved to the border regions? And then there are the refuge camps near the border reported to be under construction by the Chinese.
Next question: will these troops be like the 27 Army that brutally killed thousands in Tienanmen Square - forbidden to read any news source, told only what the cadre want them to know?
Why do they need missile batteries? Are they anti-air or surface to surface?
Maybe they plan to take out any suspected NORK nuke launch in the boost phase, knowing that if there is nuclear retaliation by the U.S. they will inevitably get fallout.
