Is it expected Han Chinese will move in to displace the Tibetans? Why are they focusing on safe passage?
This is using the Chinese definition of Tibet, which is less than half of the historical Tibet. Han Chinese are encouraged to move into Tibet (and Xinjiang) to dilute the indigenous population.
EDIT : The current Uyghur camps are a tragedy in passing to which the world is turning a blind eye. Tibet should be continuously recognized as an independent country within the world community.
The scale of the work being done to dilute the population is astounding.
We were there at Christmas time, having driven from Kathmandu. That trip was telling in itself: there was only one way to get a visa to do that trip, and all of the trips were run by a single Chinese government run tour agency.
Even with terrible roads, your can do the trip in 3 days of about 4 hours driving each. Instead they try and force most people into a 7 day tour. Luckily we got a driver we managed to haggle with and cut it down to 3 days.
Those who did the 7 days ended up staying in weird empty towns that had large hundred room hotels that were _completely_ empty, but also fully staffed.
The closer we got to Lhasa the more of this we saw. Huge infrastructure that appeared to serve no purpose other than to get people into the region.
The real solution to settlement would have to be Han intermarrying with Tibetans and raising their children as Han.
