From this:

China, famous for its export of cheap goods, is increasingly known for shipping out cheap labor. These global migrants often work in factories or on Chinese-run construction and engineering projects, though the range of jobs is astonishing: from planting flowers in the Netherlands to doing secretarial tasks in Singapore to herding cows in Mongolia - even delivering newspapers in the Middle East.

But a backlash against them has grown. Across Asia and Africa, episodes of protest and violence against Chinese workers have flared. Vietnam and India are among the nations that have moved to impose new labor rules for foreign companies and restrict the number of Chinese workers allowed to enter, straining relations with Beijing...

From Angola to Uzbekistan, Iran to Indonesia, some 740,000 Chinese workers were abroad at the end of 2008, with 58 percent sent out last year alone, the Commerce Ministry said. The number going abroad this year is on track to roughly match that rate...

...But in some countries, local residents accuse the Chinese of stealing jobs, staying on illegally and isolating themselves by building bubble worlds that replicate life in China.

"There are entire Chinese villages now," said Pham Chi Lan, former executive vice president of the Vietnam Chamber of Commerce and Industry. "We've never seen such a practice on projects done by companies from other countries."
