Wal-Mart operates over 1,000 "secret" factories in China. One of these, a
factory in Lungcheong, requires its workers to work 13 hour days, six to
seven days a week, for as little as 18-33 cents an hour — well below the
already abysmal Chinese minimum wage.
....
the Communist Chinese government is complicit in the human rights violations
that occur on a regular basis at these factories, as they allow Wal-Mart to
circumvent Chinese law.

public eyes, and away from proper scrutiny.
