Pollution, unclear regulations major hurdles for US firms

Chronic air pollution and unclear regulations are the major obstacles for most of the United States-based companies operating in China, a survey said on Wednesday.

Of the 477 companies that participated in the annual business climate survey conducted by the American Chamber of Commerce in China, 53 percent said that they experienced difficulties in hiring senior executives to work in China because of the country's chronic air pollution.

This is the first time that air pollution has been cited as a reason by most of the companies that have participated in the survey's 17-year history.
