Mr.BOATENG, the easy way is to apply for tourist visa, I know that you go to China to buy goods, however, it is hard for you to get a business visa to China, the requirements for business visa are:
Original invitation from an authorized Chinese organization, travelers cheque, round trip air-ticket, hotel reservation & Ghana company register certificate, tax clearance, true bank statement.

Properly and truthfully filled out Visa Application Form, to which one passport-size photo is attached

Valid passport with blank pages and a photocopy of the data paged

For tourist visa applcation, it is relatively easy, you can refer to http://gh.china-embassy.org/eng/lsyw/t220118.htm to read the requirements, visa fees.
