According to this article China is opening up the labor markets... it states...
"Requirements and formalities for seeking a job in China
If you want to work in China, you must meet these basic conditions:
18 years of age or older
Good health
No criminal record
A clearly defined employer
Valid passport or another international travel document
Possessing professional skills and job experience
Foreigners who are seeking employment in China must apply for an employment visa to a Chinese embassy, consulate or consular office and enter China with the employment visa. If they apply for a simple job they should apply for Z visa, and if they are highly skilled, specialists or urgently needed, they should apply for an R visa. After they enter China, foreigners need to apply for a foreigner residence permit and foreign employment permit before starting to work."
So... has the Z visa requirement ACTUALLY changed? Has anyone tried this yet?
