Let me give you an example of China's HSR project in Indonesia. Though it uses Chinese standard, this standard is compatible to world standards. In the future, Indonesians can use China's CRRC trains (biggest rolling stock manufacturer in the world), they can also connect this high-speed rail to their existing railways or use Alstom/Bombardier trains. However, Japan chose India to build their first high-speed rail in India, which means, Indians will have to stick to Japanese standard and Japanese products(Japanese are smart), which is a total closed standard. It means, India has excluded herself from the world. China won't create such closed standard, cause she is ambitious for Eurasia integration as opposed to monopolising in this region.
