Apart from Sarita, world championships silver-medallist Sonia Lather (57kg) and Lovlina Borgohain (69kg) also entered the semifinals.
Sarita, a former world champion eyeing her sixth medal at the Asian meet, defeated Maftunakhon Melieva of Uzbekistan, while Sonia edged past Kazakhstan's Nazym Ichshanova in the quarterfinals.
Borgohain defeated Erdenetuya Enkhbaatar of Mongolia by an unanimous decision.
Sarita, who returned to the amateur fold after trying her luck in the professional circuit earlier this year, took full advantage of her opponent's reluctance to attack and connected some lusty right hooks to take the upperhand early in the bout.

Sonia, on the other hand, had to stave off a stiff challenge from Kazakhstan's Nazym Ichshanova in a split verdict to enter the last-four stage, assuring herself of her second medal at the event.
She is a former silver-medallist at the continental meet.
A very aggressive Sonia had Ichshanova on the backfoot early on, the sheer ferocity of her punches standing out.
Earlier, India were not off to a great start as Nation's Cup gold-medallist Neeraj (51kg) went down in a unanimous verdict to Chinese Taipei's Chol Mi Pang in her quarterfinal contest.
The Haryana boxer was decidedly off-colour even though her right hook did come off well occasionally.
However, that was never going to be enough against a resolute rival, who did not miss any opportunity to connect on counter-attack. In the end, it wasn't a surprise when the judges gave a unanimous verdict in favour of the Taipei boxer.
