Low population density doesn't mean you don't need to upgrade your Dying old Infrastructure, in this case High Speed Rail (HST).
China maybe have Total population almost 1.4 Billion Manpower, but you need to remember.
Western area of Heihe-Tengchong Line, only have 6% of population. That's mean only 85 million people.
But that doesn't mean China don't need to Upgrade their Infrastructure in Western Area, in this case High Speed Rail.
For example, Lanzhou - Urumqi High Speed Rail Network
Lanzhou - Urumqi High Speed Rail Network
Low population density is not a reason to keep your dying old infrastructure keep alive, and don't upgrade it
That's only a Ridiculous excuses for low IQ people.
But Chinese have higher IQ, so you cannot fool Chinese members
It's the same reason like Indian horde in here always say, It doesn't matter how poor their life, how dirty their living environment, how unhygienic their food as long as they have Supa powa Democrazy, India is much much better than other country
