Here is another company that’s making ceramic and steel balls/rollers for HSR and machine tool bearings. Interestingly, bearings are the last component to be indigenized for HSR and high end machine tools. In fact bearings for all commercial 350km HSR are imported now (probably the only imported component today), and domestic ones are still under testing. Mass producing high quality bearings is way harder than it sounds

Those with expertise will not drink their political bureaucrats' Kool-Aid. The whole thing is a joke. By the time German telecom companies rip out Huawei's 5G components in 2026, Huawei's 6G commercialization will be on the horizon.
Almost everything from China is a "threat".
Chinese companies including Huawei helped Egypt build a data and cloud computing center.

China's first large-scale sodium-ion battery energy storage station officially commenced operations on Saturday. The station will help improve peak energy management and foster widespread adoption of clean energy, marking a significant advancement in China's use of clean and renewable energy.
The Fulin sodium-ion battery energy storage station was launched in Nanning, South China's Guangxi Zhuang Autonomous Region. On its first day of operation, 10,000 kWh of newly generated energy stored in the battery was distributed, fulfilling the daily electricity needs of up to 1,500 households.
"This shows a widespread adoption of sodium-ion battery energy storage technology, demonstrating China's growing prowess in renewable energy and storage. It also bolsters efforts toward dual carbon goals of peaking carbon emissions by 2030 and achieving carbon neutrality by 2060," Liu Ranran, secretary of the Standards Working Group on Lithium ion Batteries and Similar Products at the Ministry of Industry and Information Technology told the Global Times.
Funded and built by the Guangxi branch of China Southern Power Grid, the electricity storage station is able to initially produce 10 megawatt-hours (MWh). Once completed, it will reach 100 MWh, generating 73 million kWh of clean electricity annually. The output will cut 50,000 tons of CO2 emissions and meet the energy needs of 35,000 households, according to officials involved in the project.
Additionally, the storage and release of electricity is precise and intelligent. The station actively engages in peak load regulation, facilitating the flexible management of renewable energy. Technicians can monitor station equipment in real-time using electronic displays.
Sodium-ion batteries have great ability to swiftly charge, reaching 90 percent capacity in a mere 12 minutes. They also perform well in improving versatility, functioning smoothly in temperatures ranging from -40 C to 80 C, making them a prime choice for addressing energy storage needs in colder climates, according to Liu.
As sodium-ion battery technology advances, it is emerging as a cost-effective alternative to lithium-ion batteries, paving the way for China's rapid expansion of large-scale centralized energy storage facilities. The progress is expected to complement various energy storage methods, propelling the country's transition towards clean and sustainable power generation, Liu said.

China has indigenized and started production of high quality ball bearings rated for 250km-300kph speed HSR trainsets since 2020 by Luoyang LYC Bearings Corp and has passed 1.2 million km durability testing. It's only 50% of cost of foreign imports. I think your link is to a competitor company for ball bearings rated at 350kph speed HSR trainsets. So yes it's hard, but China already has it at 250-300kph and bearings are commodity items that is dirt cheap to import, so the urgency isn't high. It's usually the lengthy validation and testing, which for such a cheap product, is quite costly, hence lack of urgency.

I can hear the cries of mundane products like bicycles, blenders, etc for good quality local bearings. Forget about ceramic ones as they are too expensive. Low-quality bearings have been giving MIC a bad name.
Here's the Brazilian one (just click on the link):
You may find this quote from Nature () quite interesting. You will see that the head scientist of the European equivalent is the Brazilian scientist responsible for the Brazilian synchroton. So he lis the brain behind two of the four worlds best light source sychrotrons.
I suppose he is the guy to hire if you want one of those toys.
