Asian Games silver medal winner Manpreet, on the other hand, got the better of Algeria's Bouloudinats Chou 15-12.
The 17-year-old Shiva, a silver-medallist from the Youth World Championships and a bronze-winner from the inaugural Youth Olympics last year, defeated Scottish boxer Joe Ham 5-1 to book a semifinal berth in the event where India has been invited for the first time.
