There are also many products manufactured in the UK and exported to China, which are not counted as chinese CO2 emissions. And I don't mean just expensive cars like Bentley, Land Rover or Jaguar. British industry is quite huge. E.g. all airplanes used in China were manufactured in Europe or the US, so you could say "China is outsourcing their industry to Europe and the US to keep their CO2 emissions low".
