Medical for Scholarship to study for 1 year in China (UK citizen)

Hi, I've applied for a 1 year scholarship to study in China.
The University I'm applying for does require a medical examination and they offer the form for download online. But it also states that you can have the examination done on arrival (as mentioned above) if you haven't done so already.

Is it more cost effective to complete the medical examination in the UK or wait until arrival in China?
