Inquiry about edexcel alevel examinations in china

I'm a Sri Lankan student who is about to start a language program in china this month .And also I have to write my edexcel Alevel biology physics and chemistry in May June session but since I will be residing in china in that period and I can't travel back to my country to sit my alevels so will I be able to sit my alevels there in china as a private foreign student? If so which centers allow this?
Also I have done my olevels in local curriculum and I'm only doing my alevels in edexcel syllabus so there won't be any school association I will be a private candidate
Pls clarify me with this
I have already sent an email regarding this but I haven't received a reply yet
