It is the Roewe i5 in China.the China pricing is always very confusing because the government there is constantly changing its subsidy policy. But at the moment on the website www.saicmg.com you can see a new ICE ZS starts at £9,600 (!), the EZS £14,400, but they don't sell MG5 EV in China, that bodystyle is sold as MG6 but only as a PHEV. this is typical of MG whose lineup tends to chop and change and vary considerably, they are still trying to get rid of RHD ICE MG3 hatchbacks here which they stopped selling in China years ago. As for price differences in China, you can watch a premier league game for 60p live whereas in the UK a now TV daypass is £10!
I think in other markets such as India and the Philippines it's an MG5.
The MG6 in China is a different car (and a better looking one) they didn't bring the newer MG6 to the UK (like the previous generation). It is Octavia sized (somewhere between a Mondeo and a Focus).
