Amir, maybe you can apply for a business M type for that. You need to provide your passport and copy of its data page, the completed application form attached with 2 passport-style photos, an invitation letter from your business partner, a duly authorized invitation letter, letter of undertaking and business license copy of your company, bank statement, tax certificate, as well as transportation and accommodation arrangement. Next, go to the embassy of China to submit the application.
