how i can get business type from pakistan? what will be its fees with time duration???

Ahsan, first of all, you need to prepare the following materials, including an invitation letter from duly authorized unit in China, an invitation letter from your Chinese trade partner, a guarantee letter from your company, your income tax receipt, the photocopy of your company's business license, a bank statement of the latest six months, and round-trip tickets and hotel reservations.

Then take your passport, a copy of the passport's photo page, a filled application form attached with your recent color bare-headed photo, and the above-mentioned documents to the embassy and submit them.

No matter what type you are applying for and how long is the stay duration, you don't need to pay any money.
