China is the only country controlling the rare earth, and the quality of the western commercial jetliners might become more dubious if the rare earth war has been escalating into the civilian manufacturing domains.

Yes of course
That will enable Comac to produce more aircraft. The company has difficulty to make aircraft due to different reasons. And one is US sanctions.
I did say that months or years ago.
From the visit of To Lam and other Vietnamese companies to China, it appears to me that in addition to acquiring more aircraft from Comac and opening more flights to China, a production line in Vietnam is under discussion.
VietJet Air to lease up to 10 C909 jets in boost for Chinese aircraft maker
Deal follows talks between Chinese and Vietnamese presidents in Beijing this week.www.scmp.com
The Comac executives were naive for trusting the west that using their engine in exchange of their certification.
C919 will start to test its domestic engine CJ-1000 in Q2/Q3 of this year, then it will start to mass produce with its domestic engine.
C929 will never use a western engine again, it might not have the same problem as C919.

I know why To Lam took long ride of 2400 km on Chinese HSR. He wants to find out how long distance HSR is operated successfully in China and how the Chinese HSR has brought developments of the cities and towns along the line. All these experiences will be applicable in building and operating Vietnam's N-S HSR in the future. Anyways, Vietnam really needs a North-South HSR, and its geography of long but narrow strip of land is especially suited to build a HSR to efficiently connect parts of the country.

The decision is made to cover Vietnam with HSR. There is no going back. There are numerous reports of Vietnamese traveling on China HSR, he probably just wants to experience himself.
Of course we need to develop the entire country, not just Hanoi and Saigon while turning the rest to slums.

My parent's generation used to go to East European countries to study by train in 1960s via China, Mongolia and the Soviet Union, but probably it is the first time ever a Vietnamese top leader has gone all the way from Beijing to Hanoi by train.
(The train carries Mr. To Lam from Nanning to Hanoi. He took a high speed train to go from Beijing to Nanning.)

Vietnam tests next-generation ultra-fast internet technology
[VOVWORLD] - The Viettel Military Industry and Telecoms Group announced on Friday it had successfully tested two next-generation fiber-optic access technologies: 25G PON and 50G PON.
(Source: Thanh Nien newspaper)
The 25G PON achieved real-world speeds of up to 21 Gbps, while the 50G PON reached 41 Gbps. With these results, Viettel becomes the first telecom operator in Vietnam to trial ultra-broadband technologies, keeping pace with leading global providers.
Mastering 25G and 50G PON is expected to bring significant benefits for both individuals and businesses. The infrastructure could enable new applications such as 8K video streaming and extended reality (XR). For enterprises, it provides a critical foundation for smart factories, digital twins and real-time remote control systems with near-zero latency.
While Viettel has yet to announce a commercial rollout timeline, it said that following further evaluations, it plans to introduce ultra-high bandwidth service packages ranging from 20 Gbps to 40 Gbps for specialized customer segments, while continuing research toward more advanced technologies such as 100G PON.
