Winning this first HSR project in India is a good start for Japan, I believe Japan will continue to dominate HSR business here in the long run. China will do smaller deals like feasibility studies but not large sale finance, production or operation.
Given limited capacity of financing, manufacturing base, etc., and large global demand (at least 28 countries) on railway or HSR, it would be a paradigm of constructive competition to adopt
segregation of markets. Japan already has India, Philippines, etc. On top expanding huge home market, China focus on Turkey, Russia, Indonesia, C&E Europe.
Let's apply such mutually beneficial practice on other markets like South America (Trans Continental Rai), Mexico, US, continental ASEAN (Pan Asia Rail), UK (London HS2), etc. The market is bigger than we might cater for.
