Pcad has it right (egads...). You can and should be wary of some Chinese product w/o being xenophobic. Here in S. Fla, home of the housing bubble, "Chinese Drywall" (sheetrock) is a 4 letter word. Stuff gave out chemical gases that smelled and literally corroded electrical fixtures. People sued but there was, ultimately, no one the courts could reach. Brand new houses were having to be completely gutted of interior walls and ceilings.

Of course most of those houses are vacant and in foreclosure now......
