So you are saying that there's a QA process that somehow determines which devices will have a transistor pop in a year, and then they send those to eastern Europe? That sounds... unlikely. But then again, I know nothing of chinese QA. My assumption would be that it varies greatly between factories. There's cheap stuff from China, and there's expensive stuff from China, and the quality varies accordingly.
You don't need to know anything about the Chinese QA process. This is how QA is done for literally everything. What exactly do you thing QA is? The cheap batteries you buy from ebay are batteries that were rejected to sell at a store in the west, and rejected to sell at a store in the east.
I'm not trying to change your mind on anything here, as you seem to have your mind set before bothering to spend even a minute looking up something you stated yourself you know nothing about.
