The delusion in this thread is mind boggling lol. In what way is India competitive in building any infrastructure mega project outside of its borders?
What do they bring to the table? financing? technology transfer? cheap materials? Or just cheap labor?
What is in it for the other countries?
How is those lines economically viable, and if not, is the Indian government going to foot the bill? What's stopping them from not paying like every other time?
I can see the benefits for ASEAN stretching the line from Singapore to the coastal regions of Burma, and linking up with China in Yunnan. Going to Bangladesh might be a stretch but workable if their economy continue to develop and are a viable pool of cheap labor.
The way I see it, the only viable way this route can come into being is if Singapore/Malaysia and Thailand push for additional rail capacity after the first connection to China prove to be viable. Then the next stage would be an extension into Burma and possibly completing the loop into Yunnan. Then a next stage into Bangladesh, but this would probably be like 20 years down the track and Bangladesh gets close to where Thailand is today thus presenting a massive market opportunity. After that is complete would the option of connection to India open up, and they will probably just go to Kolkata and the Indians will need to sort out their poor North East themselves.
End of the day, India today isn't fit to lace China's boots when it comes to its infrastructure construction or financing. It might talk a great talk, but its got nothing to back it up, especially when it can't even build out its own networks, let alone competing with China. (Leave it to Japan, Euros & Americans)
