I was under the impression that China is doing relatively small exercises to simulate a Taiwan invasion, D-Day type.
If China is mobilizing beyond that, it's disturbing news. I haven't been able to keep up with the other threads, now am determined to make the time to keep up with this one.
They've also mobilized 150,000 troops to the NK border area, which is the same general area in which 150,000 Ivans are conducting an exercise.
