I do not agree - at least in electrical and electronic stuff I deal in.
There are 10,000s Chinese suppliers of that stuff. But, I like others, need certificates of compliance ... lab tests by accredited labs ... before I can legally sell the stuff in the West.
And, I also look for ISO quality control systems.
It is darn near impossible to find Chinese suppliers with both the right lab certificates and ISO systems when dealing in electrical stuff (and the many other sorts of goods which must comply by law with various standards in different Western countries).
For example, I recently dealt with 45 Chinese suppliers (yes, 45) of a particular CFL light bulb I needed in large quantity.
Not even one of the 45 had the lab certifications (like proper EMC and Electrical Safety Reports) I needed to legally sell the CFLs in the West.
Take mobile phones. It is darn near a criminal offence to sell mobile phones in the West without proper SAR etc lab reports (and in USA they will lock you up). How many of the mobile phones offered by Chinese suppliers have the correct lab reports ... it's SFA. The SAR test is to ensure that emissions from the inbuilt phone aerial are at a safe level when held against the ear.
Sure, China has its own Standards for various products but Chinese labs will issue back door certificates to Chinese factories which are fraudulent and of no use in the West. It is part of Western law that the lab must be accredited. Problem is, there are only a handful of accredited labs in China.
Finding the right Chinese supplier is like prospecting for oil ... a huge amount of time and money must be put into the search. Then, upon finding the right supplier, you do not tell anybody else as the knowledge is just too valuable.
It will probably take most Chinese factories another 10 years to wake up the fact that proper certification to Western Standards and ISO systems is essential to export sales success.
Quoting from [shaniayyh]:I am a supplier,I ama lways feel that it's so hardto find a buyer ,I wonder why the buyer is difficult to find a seller,and th seller are also dificultto find their clients ,why this can't match well,maybe some the buyers can't trust the suppliers for the first time .if we have more trust ,this will not problem
Trust is certainly a factor that slows the process down, but it should not put an end to possible business unless you are doing something very wrong.
I think that it has more to do with patience. I find that Chinese are on the whole a very impatient group of people. I don't mean this in a bad way, but it certainly helps to explain why sellers often appear to be so desperate for customers.
Foreign buyers often like to do things carefully, methodically, and strategically. Therefore a contact about an item price today may not result in an order until six months later when the customer is ready to introduce the item to their range. I think that many Chinese sellers expect, and quite understandably, want the process to go much quicker. When it doesn't they think that something must be wrong.
My advice to suppliers when dealing with new customers is to be professional and let them know that you are ready to do business with them. When they are ready they will come back to you. And if they don't then you haven't lost anything except for some time corresponding with them.
