Need to obtain a business visa for an Exhibition which shall be commencing on Feb 19 in China

do u have any invitation from the exhibition? how can you atttend the exhibition if you don't have any invitation or permission?
any documents from the exhibition will be fine.
to obtain the visa, you have to prepare all the documents and submit them to the Chinese embassy or consulate General in your country. you'd better start your application as soon as possible.

Thanks..

Can i go as a tourist? If Yes what would be the process.

yes, you can go as a tourist.
to apply a tourist visa, you need to provide round-trip air tickets, hotel reservation in China, your valid passport, fully completed visa application form, and passport-size photo to the Chinese Embassy.
