I think that the short answer is that with the several accounting scandals arising from Chinese r/m companies that no one trusts them or their accountants. Add to that, the dog food scandal a few years ago, Chinese drywall, unsafe chemicals in toys, etc., it just boils down to no one trusts the Chinese when it comes to business ethics. I have worked with several Chinese nationals and their business ethics are not the same as ours.
Not all is deceitful, as there are cultural differences, and some practices are acceptable in China, but not here. And some of what is referenced above is just shoddy product worksmanship. Ditto with many Europeans and Indians. Some times the crooks are the Americans who handle the r/m's and are taking advantage of these cultural misperceptions. I work with a lot of New Yorkers, too - 'nuff said.
However, when you throw all of these ingredients into the pot and stir, it often results in an unsavory stew.
