Poojashree made a good debut as she thrashed Si Ying Julienne Keong 6-1 6-1 in the opening rubber to give India a 1-0 lead.
Seasoned campaigner Sania then clinched the tie for India by beating Li Yun "Stefanie" Tan 6-2 6-3 in the second singles.
Veteran Rushmi Chakravathy and Sanaa Bhambri combined to beat Clare Fong and Stefanie 6-0 6-2 in the inconsequential doubles rubber.
India will take on Malaysia tomorrow and will have to beat the hosts to top Group A and thus qualify for the play-off tie, where a win would catapult them back to Group I.
India were relegated to Group II last year.
