A "blitzkrieg" tactic is an umbrella term that is used to refer to an attack in which the aggressor attempts to overwhelm and capitulate the enemy by launching coordinated, multi-front, and most importantly, surprise assaults. Such requirements don't always include a freaking 10-hour artillery barrage like the Germans did during WWI or a Pearl Harbor style attack; any operation that catches the enemy off guard and manages to break through their defenses using surprise can be seen as such.
This means that the 1962 skirmish (it's not a full scale war since both sides restrained themselves) was in some respects similar to a blitzkrieg tactic, since the Chinese used coordinated mortar assaults in the opening front, but ultimately wasn't since India was expecting a counterattack after Indian troops were initially sent to occupy disputed territory.
But to say that the Chinese aren't considering the concept is simply ridiculous. First of all, after China extensively studied the Gulf War and such, the PLA embarked on a huge program to develop such weapons, such as long range cruise missiles (CJ-10, CJ-20, YJ-62, CM602G, YJ63, etc). They also developed the long range delivery mechanisms that would be needed to launch such "shock and we" assaults. Finally, their development and focus in stand off weapons seem to be in tandem with the notion that they are leaning towards the "shock and awe" tactic.
The notion that China doesn't plan on studying "blitzkrieg" tactics because they haven't done so is also erroneous. Every type of conflict calls for a different strategy and action. Just take a look at Vietnam and you'll see how "shock and awe" isn't always the way to go.
Sure, anyone can believe that China is "threatening" other countries when they turn a blind eye towards what caused the Chinese to react the way they did, such as Japan's unilateral purchase of the disputed islands.
