It is not the responsibility of the Chinese government to check if the goods exported meet the standards of the destination country but rather it is the responsibility of the destination country to control that imports meet their standards. Just like it is not the responsibility of the Australian government to check if the goods exported meet the standards of the destination country but rather it is the responsibility of the destination country to control that imports meet their standards.
I don't think this is right, is it? You are talking about self-certification, and it was introduced specifically to avoid the importers having to check every product for compliance. Think of how many products come into the country from China - making the importers responsible for checking compliance of every different product with all the relevant standards is ridiculous. Impossible, actually. Self-certification is based on trust, but backed up by a big hammer: in the EU, at least,
the directors of the certifying company are personally liable for misuse of certification marks. This was innovative law when it came in: up until then, companies were sued, not individuals. It marked a sea change in EU law.
Now of course this does not apply to Chinese companies. You can forget fining or jailing the directors of a Chinese company, because their government ensures they are untouchable.
I agree that the Chinese government is not responsible for the products coming out of a Chinese factory. But the government DOES set the business culture, and it DOES make it almost impossible to seek compensation or retribution for non-compliant products.
I've bought various things directly from China, not via a UK importer. Many times I have a good experience, but sometimes I get scammed and receive a two dollar plastic toy, rather than the 20 dollar product I wanted. And I know, beyond doubt, that there is no chance whatsoever of getting recompense. In fact it's usually impossible to pin down who it was you actually paid. Company names come and go, addresses change, correspondence is invariably ignored, and the supplier is effectively untouchable, assuming you could even find them. The suppliers know this.
Of course, it's a different story for big western companies like Microsoft and Apple: their relationships with Chinese suppliers is much more equitable and they do have the power to get exactly what they want from the manufacturers. And it proves beyond doubt that some Chinese companies, at least, are capable of producing top class quality products. Maybe better than we in the west can do.
