I am sure if you can container it, they can take it - from what I can tell, its just containers on flat rolling stock. And they swap rolling stock based on rail guage, and in some places, for fuel availability ( apparently its not all electric ). So maybe cage it, ship it.
having said this - isnt China quite a hard place to work through on the legal side ? in that you need to pay for an 'escort' person / vehicle to come along everywhere you go ? and there are restrictions on travel away from cities and major highways ?
