Investment seeking Bangladesh's economy is hungry for local and international finance for its infrastructure development. One Belt-One Road (OBOR) seems opened a golden door, not only for Bangladesh's economic reform but also created an opportunity for higher bilateral cooperation between China and Bangladesh. The geographical location of Bangladesh is playing a vital role despite being a small economy and territory in the region. Covering three sides of the Bangladeshi border, economically emerging state India has a sharp eye look on Bangladesh's strategies and policies more than any other time.
