Especially considering Guangzhou-Wuzhou-Nanning is already 200 km/h. As is Shenzhen-Fuzhou.

There is talk that a line from Pingxiang (on the border with Vietnam) to Nanning will (or has) started construction this year.

Guangxi to build transport network

A high-speed railway from Nanning to Pingxiang, which also borders Vietnam, will begin construction this year.

While according to a map posted by tjrgx, the Nanning to Chongzuo is under construction.

I agree and mixed use at that, because lets face it, freight pays the bills while us passengers are just for fun.

That is also true, at least for somewhat remote lines like this.

Anyway one has to be a bit pragmatic too. If we imagine Hanoi-China HSR then the first question is what is the closest large (2 million+) Chinese city? Clearly answer to that is Nanning with a potential onwards journey to Guangzhou and Hong Kong. Can it be reached in 3 h or less (boundary above which flying becomes competitive)? With 350 km distance for sure possible. Is 350 km/h standard needed to achieve it? Clearly not - 200 km/h running speed with about 170 km/h average will nicely accomplish the task at hand. This is assuming of course that the current separate border procedures requiring more than an hour could be simplified.

Have a look around Guangzhou then.
Direction 1: Guangzhou-Changsha. 621 km. 300 km/h line.
Best time - 2:17, G66
Direction 1 onwards: Guangzhou-Wuhan. 968 km. 300 km/h line
Best time - 3:38, G66
Direction 2: Guangzhou-Nanchang. 300 km/h line
Best time - 3:44, G86
Direction 3: Guangzhou-Fuzhou. 842 km. Of which first 102 km, to Shenzhen North, is 300 km/h and the remaining 740 km is 200 km/h.
No service.
Direction 4: Guangzhou-Guiyang. 856 km. 250 km/h line
Best time - 4:15, D212
Direction 5: Guangzhou-Nanning. 577 km. 200 km/h line
Best time - 3:18, D204
Direction 5 onwards: Guangzhou-Baise
Best time - 5:36, D3830

Even the high speed train from Nanning to Pingxiang checkpoint has become a reality, there is a bone of contention at the border - 2 hour of immigration process at Pingxiang (Chinese checkpoint) and another 2 hour of immigration process at Dongdang (Vietnam checkpoint) due to the animosity between these 2 nations

We are dreaming about some distant future when relations are better and full line has been built. Right now the logical thing, unless the budget is very tight, is to fly...

For this to work immigration would have to be quick, under one hour for sure, and at only one place.

then, the treaty for cross border rail traffic is necessary - For the line from Nanning, Pingxiang should be international station while the line from Kunming, Lao Cai should be international station for the parity

BTW, even the high speed train manage to cross the border to Vietnam, the station should be Gia Lam as Hanoi station for Unification Express (Hanoi - Saigon) does not have enough space for High speed train

Thailand should be vitally interested in a high speed railway Vientiane-Vinh-Hanoi...
