On May 25, U.S. businessman Charles Hubbs made the short trek to Hong Kong from his office just outside Guangzhou, a city in Guangdong province in southeastern China that is known for good reason as the manufacturing workshop of the world. For the 64-year-old native of Louisiana, it was a trip that may have marked the beginning of the end of his successful 22-year run as a China-based exporter of medical supplies.

Hubbs was going to listen to a pitch from the American ambassador in Cambodia, Carol Rodley, and the president of the American Chamber of Commerce in Phnom Penh. Their aim was simple: to get foreign investors, particularly those already with operations in China, to consider setting up shop in Cambodia. Hubbs was all ears. To hear him tell it, the price of labor is on the brink of making his firm, Guangzhou Fortunique, which supplies some of the U.S.'s biggest health care companies, uncompetitive. "We've seen our wage costs in China go up nearly 50% in the last two years alone," he says. "It's harder to keep workers on now, and it's more expensive to attract new ones. It's gotten to the point where I'm actively looking for alternatives. I think I'll be out of here entirely in a couple of years."
