Swedish citizen traveling through Beijing to Sweden

My flight-plan is the following: Leaving from Kuala Lumpur, Malaysia to Beijing, China to Kiev, Ukraine and finally to Stockholm, Sweden. My layover in Beijing is 22 hours. My question is do I need any sort of visa? I have no interest in leaving the airport for the waiting period. I visited Beijing almost 6 months ago if that is of any importance.
Thank you very much for the quick replies.
