Typically, these are for new cars. A Range Rover that goes for $60-70k here in the US might go for $200k in China. Jaguar wants to protect that pricing in China, so they penalize American dealers for selling cars that end up overseas. Jaguar is the strictest with the rules and puts a cap of something like 3%, so if more than 3% of what a dealer sells ends up overseas they get penalized. That means that dealers will blacklist people who are straw buyers.
