As far as I know, bank statement is not required when applying for Chian Tourist visa.

Dear Sir,

so which documents i need to submit for tourist visa

I think you need the following documents, but it depends on the China embassy finally:
A. One completed visa application form;
B. One recent passport sized photo;
C. A valid original passport with blank pages.
D. Travel information including the booking of airline ticket and itinerary in China.
E. Hotel Booking.

Dear Sir,
Many Thanks !
Kind Rgds
