I want to go and buy equipment in CHina for my Startup

You need to provide your passport and copy of its data page, the completed application form attached with a passport-style photo, an invitation letter from your business partner and the duly authorized invitation letter, bank statement, round trip air tickets, and hotel booking record, your company's business license, and business registration as well as the tax certificate. Next, submit the application to Chinese embassy to apply for business M type.

Hello,
I have two questions:
1. What are the fees for Business M?
2. What is the difference between an invitation letter from your business partner and the duly authorized invitation letter?

1. XAF50,000 per person. 2. You can find an individual to provide the invitation letter, but the duly authorized one needs to be applied from Chinese government.
