Hello, I will be applying for a China visa but I'm not sure which one would be appropriate, between Tourist and the Business. Here is the situation:

I will be giving a short talk at a local institution. I have been invited to do this, but there is no official letter of invitation, nor any monetary transaction it. I am also *not* a business man, nor do i work professionally in the field of what I'm discussing. I will be covering my own hotel stay, flight, as well as everything else. Total trip duration will be 6 days.

My contact arranging the speech lives in france, so i don't believe I have easy access to a formal letter of invite from the location of the talk. I have been advised that a tourist visa would work, but that technically a lecture is listed under the Business visa.

Can you recommend which is the right one to apply for?
