The little consolation and consideration for the One Belt portion of OBOR is to cater for the needs of countries like Indonesia and the Philippines that trains could not reach them. The game of trade through sea ports would be totally changed.
What about Singapore becoming irrelevant in the game plan? If Singapore and Malaysia would play the game right, both could be playing a new role as the new trading centres and the terminals for high speed train. All goods from and to Indonesia could land in Singapore and go forth by land to Asia and Europe in double quick time. The caveat, if the high speed train terminal landed in Singapore. Missing this boat will mark the end of Singapore as a trading centre for the region.
China is playing on a chess board that is as big as the whole world while the Asean countries are bickering over the South China Sea and thinking that it could hold China to ransom by choking up the Straits of Malacca. The Chinese have thought through their strategic interests and have mapped out their plans, on land, by land and minimizing the need for sea transportation to a minimum.
The OBOR and the high speed train and road network across Asia to Europe and Africa are game changers to a new world of global commerce.
