Does trade route pass through neutral country?

[I had a bad name 99]

I am playing as UK, and there is a decision to open Burma road. However, I am not involved in Sino-Japanese War, so what is the point of building up infrastructure in Burma and Xikang (the Chinese territory directly connected to Burma)?

China has lost all its Eastern coast ports, so do they actually get their imports and supplies via overland Burma?

You mean a national focus, named 'The Burma Road', not a decision.

There is no point for you of building up infrastructure in Burma and Xikang if you don't want to be directly involved in Sino-Japanese War. But the additional infrastructure, airbase and military factory built on the Chinese side may indirectly help your Chinese friends against your (future?) common enemy.

China has lost all its Eastern coast ports, so do they actually get their imports and supplies via overland Burma?

Yes via British Raj, or any other neutral or friendly territory connected by land. You as UK can also trade with or send lend-lease to China via British Raj. And China should be able to trade with you, via British Raj, if they have convoys.
