Mr.kamran Ch. I think it is hard for you to get a China visa to China. For business purpose, you shall apply for Business Visa, you need
1. the Original Visa Notice Sheet from an authorized governmental apparatus /organization in China prescribing the visa validity, number of entries and stay period
2. Invitation letter from the company/organization/institution you want to visit in China

if you don't have them, you can't apply for business, as for the tourist visa, if you don't have relatives in China, you can't apply for individual tourist visa, for more information, please refer to http://pk.china-embassy.org/eng/lsfw/t379810.htm
