The two-day conference in the Thai capital begins on November 27.
She pointed out that businesses set up in Bengal can expand their operation to other Asian countries due to the geographical proximity of the state with countries like Malaysia, Myanmar, Kunming in China, Bangladesh, Bhutan, Bangkok, etc.
