Day 7, but continue to post here.
China defeated Korea in a close finish. This is significant for Olympic qualification. China with their 2nd win, but I believe this still isn't a guarantee to get that best ranking in Asia.
The final world cup ranking depends on their *placing* within each group of the classification round, not necessarily wins. Currently Iran and China are both placed 2nd in their respective groups. I can't find any clear information about how they are ranked from there, but I assume it is based on wins then points differential.
China will play Nigeria next. Iran will play Philippines.
So if Iran beat the Philippines as expected, and China loses to Nigeria, they will both finish second in their group and Iran could get that automatic Olympics birth from points differential. Although knowing FIBA, they might obscure the final placings system to somehow let China into the Olympics anyway.
