According to the region lock information in the bundle thread, this key can't be redeemed in China, thanks to Sensualshakti for the info. I did my best to select the countries that can redeem it. Anyway, should any problem (doubt it) arise with the key, I'll ask you politely to allow me to delete the giveaway.
