纳米比亚 (Nàmǐbǐyà): Namibia
Namibia is a sensitive word in China because of a corruption scandal involving Hu Haifeng, son of former president Hu Jintao. (See more about this on CDT.) Hu Haifeng is the former CEO of Nutech, which was the subject of a bribery investigation by Namibia. The investigation probed how Nutech received lucrative government contracts.
A Baidu search for Namibia will still produce a number of results; however a search for “Namibia Hu Haifeng” (纳米比亚胡海峰) causes the Baidu search page to completely vanish and to produce an entirely white screen. The forbidden query causes Sogou even more serious indigestion, shutting down access to the site for several minutes (as of at least 7/31/10). A Google search produces over 19,000 results.
