Help from Japan?
we have earned annually over 200 billions trade surplus with US in 1990s, Japanese cheap credit is just a "better than nothing" but we don't need Japanese help, when China has realized Japan was playing dirty trick, we go all the way with Germany regarding the manufacturing machine and tooling.
As for India, first you don't earn much as trade surplus as China did and how you expect that this 50 billions Japanese's credits will make India competitive? most likely Japan will eat back 25 to 50% of this credit as profit by building high speed rail for India since India know nothing about the real value of high speed rail project.
You can always follow us but your governing system will make you a failed imitation, India is simply not China and you Indian don't work like Chinese, most likely India will have shoulder the burden of debt for generation to come.
