In a translated statement from Samsung regarding the China version of the Galaxy Note 7, it reads, “Country line version from September 1 officially on sale in the Chinese market, the use of different battery suppliers, not in the replacement category, Chinese consumers can rest assured purchase.”
Basically due to the suppliers being different for China and the rest of the world, it seems that the Galaxy Note 7’s batteries in China aren’t affected by whatever problem that is causing it to explode. Samsung has claimed that there have been about 35 reports so far, which we guess in the grand scheme of things is but a tiny fraction.
However this has not stopped the company from announcing a global recall (save for China) and launching an exchange program in the US, where customers can choose to replace their phones for a brand new one, or replace it with a different model like the Galaxy S7 or S7 Edge instead.
