My colleague Mike Fenner pointed out a website that compares the China and EU RoHS laws. As vague as many complain that the EU's RoHS and WEEE directives are, China RoHS may be more so. In addition, hardware that conforms to the EU directives may not conform to China's. Ouch! In truth, I expect convergence as the dust settles.
Mike also points out another website that discusses these issues. Check them out, we all need as much information on these confusing topics as possible.
