New Delhi, India (BBN)- Indian External Affairs Minister Sushma Swaraj reached Dhaka Wednesday night on a two day visit.

Earlier, she spoke to West Bengal Chief Minister Mamata Banerjee about the two-day trip Ahead of her visit to Bangladesh.

According to official sources, Swaraj made a call to Mamata to "touch-base" and tell her about the visit during which the External Affairs Minister will hold talks with top Bangladeshi leadership on key bilateral issues including Land Boundary Agreement (LBA), proposed Teesta river pact and illegal immigration to India, reports NDTV.

However, the sources refused to give any further details about the conversation between Swaraj and Mamata.

Swaraj's call assumes significance given that Mamata's party Trinamool Congress prevented the previous Congress-led government from signing the Teesta water sharing deal with Bangladesh.

In 2011, Mamata, then an ally of the Congress-led UPA, backed out from Prime Minister Manmohan Singh's Bangladesh visit, opposing the Teesta water sharing treaty between India and Bangladesh, following which it was shelved.

The Indian delegation, which is expected to raise issues like illegal immigration and market access, is also prepared that Bangladesh will raise the "touchy" issues of LBA and proposed Teesta river pact during the visit beginning tonight.

This is Swaraj's first stand-alone foreign visit after becoming minister.
