Just to make a statement of some kind, the feet equivalent of these levels are all 100 feet above existing RVSM, ie FL351,361,371 etc. This means there will be transisions from surrounding RVSM areas, although simpler than RVSM/feet<->NVSM/metric, it still means you will have to climb/descent 100 feet to comply
As mentioned above, it should be followed up by larger capacities at aerodromes in China, as well as making sure there are a sufficient amount of controllers (and sectors) to avoid congestion.
All in all, good move China, you are on the right track!
