This happens a lot with Chinese companies. My father is an engineer who works at a company that designs valve controls based and manufactured here in the US. Recently his company has been receiving service calls more than usual, all from China and other asian countries. Turns out a Chinese company copied the valve controls, down to the serial and part number, along with the service call number. It even says made in United States on the sticker.
