I have an AirPort Express purchased in China.
But it only work on Channel 1-11(2.4 GHz) and 149-161(5 GHz).
China law allow Channel 1-13, 36-64 and 149-165. see http://en.wikipedia.org/wiki/List_of_WLAN_channels
* I'm a Chinese but no one can answer the question on Apple Chinese support communities.
* Please excuse my poor English.
AirPort Express 802.11n (2nd generation), OS X Mavericks (10.9.5), AirPort Firmware 7.6.4
Apple is not up to date with regulations everywhere..
You should pass a support query requesting they update the allowed channels on the China release products.
For now there is nothing you can do about it..
According the same reference those changes only came in at the end of 2012
China MIIT expanded allowed channels as of Dec 31 2012 to add UNII-1, 5150 ~ 5250 MHz, UNII-2, 5250 ~ 5350 MHz (DFS/TPC), similar to European standards EN 301.893 V1.7.1.[41]

Thanks.
But Channel 12, 13, 165 is unavailable in my AirPort Express. Other routers sold in China are supported it.
As LaPastenague says.......For now there is nothing you can do about it.
You should pass a support query [To Apple] requesting they update the allowed channels on the China release products.

When Apple updates the AirPort Express for China, your problem will be resolved.
