Hmm,so u were here recently. No,chennai is 6 largest by population. Its airport and other facilites are good but there many others better than that. Its not just the case of tier1 cities like chennai ,even airport of tier2-3 cities in India are upgraded to International standards. There are many other projects under development in chennai with many other to come,i suppose. We have been slow bt that has do with the slump in the economy post european crises,from 9% economy fell down to 4.5% ,in that case its pretty hard to grow for any city,let alone chennai.but things are improving now, still the fact is it's still slower than china. Worst problem is they lack planning to turn chennai into a more modern city,its a bitter fact. Which wasn't the case of shanghai 20 yrs ago.
But then again we aint 20 yrs behind china,it hovers between 12-15 yrs.
That's what happens when labours cost is rising u tend to search for a new market. Just like it was the case of west flooding china in 80's & 90's. Chinese wouldn't be that stupid to miss their turn now to invest in India.
