China is to start fingerprinting foreigners on arrival:

(At Luohu there's a new turnstyle after passport control for scanning visas; perhaps a fingerprint scanner will be added.)
Let it not be forgotten why Americans can not get visas on arrival in China, such as the five-day Shenzhen visa at Luohu: because the Chinese government blocked those visas for Americans in 2004 in a fit of pique over America fingerprinting visa applicants.

Any bets on how soon China will rescind those restrictions? All on the basis of reciprocity, of course.
