Golam Rabbani Chhoton's charges won 2-0 against the United Arab Emirates in their opening group 'B' match at the Bangabandhu National Stadium on Monday.
They will face Kyrgyzstan in their second and final group game on Friday.
The home side doubled the lead on the 30th minute. Krishna Rani found the back of the net with an emphatic header from Monica Chakma's corner kick.
The hosts kept up the pressure on the UAE in the second half but could not increase the margin of victory. On the 49th minute, Shapna was played through on goal with only the keeper to beat. But her shot was straight at the goalkeeper.
Bangladesh have now won their first meeting with the UAE at the Under-19 level. Bangladesh had triumphed against the UAE on three occasions in the AFC under-16 Championship qualifiers. Bangladesh won the last encounter between the sides by 7-0 in 2018.
