I will be updating polygon data for China as well. I assume there aren't many Challenge Checkers using their regions.
Project-GC does not have county support for China today, and will not have after the update either.
The number of regions will increase from 33 to 35.
Every single region will be renamed, today they are named in both Chinese and English. The new names will be in International English only.
I will post the output of the compare-script in the next post, but I would expect everything to be false positives.
