The Chinese government does not acknowledge copyright or patents issued anywhere on the globe, and as such, the companies there rip off computer design, automotive design, and any other design that they want. They don't incur the R&D costs, they don't have the same production costs as a lot of other countries, and because the US and Canada don't have sufficient testicular fortitude to impose stiff import taxes or outright deny the importation of goods produced with stolen intellectual property, they just keep doing it.
It's like having a child that you catch having his hand in the cookie jar, and then not only not scolding him, but BUYING the cookies from him.
