Greetings, I want to apply Visa for China for a conference!

For this purpose, you need to apply for a business visa. Invitation letter is required. Other documents needed are your passport, application form and photo. Sometimes, you may be required as well by visa officers the return ticket, hotel reservation and bank statements. SO, you'd better prepare them in advance. The processing takes 4 working days and it can be done in shorter time if you pay extra money for their rush or express service.

There is also the possibility of obtaining type 'F' Visa for this right?

Yes, you're right. F visa is for business purpose to China.
