discussion keeps the world turning.
This is Roundtable.
Two decades after the Qinghai Shijang Railway first cut across the plateau,
the track tells a bigger story than just engineering marvels.
It has rewired daily existence at 4,000 meters from supply chains to tourist flows to the exchange of ideas.
But here we are 20 years in, and fresh challenges are surfacing.
How does progress sustain itself at such altitudes, and what should the next phase of this railway actually be?
Deliver.
We're live from our studios here in Beijing.
This is Roundtable.
I'm Steve Hatherly.
Thank you so much for being with us today.
And for the show, I'm with Yushan and Guoyan.
First up...
20 years after the Qinghai Shizhang Railway began operation,
the journey across the plateau is no longer just about crossing the roof of the world.
It's also a story about how connections reshape everyday life.
Faster access to goods, growing tourism,
and new networks of people and information changing life at 4,000 meters above sea level.
But after two decades of transformation, new questions are here.
