Why do you think my commends were from an ignorant child? The planning, design and construction, all were done by Chinese companies. Only the land and river were given by BD.Lol, what an ignorant comment. BD economy and people life's will improve with this facilities that help boast every single aspect of BD. Shorten transport time. Improve competitiveness.
So, all credits of construction the tunnels go to China. Am I wrong?
