Why would they get permission to get onto the top 500 list, when other Chinese exascale supercomputers haven't? There are research papers made on them already, so they do exist.

The research team of Professor Qu Liangti from the Department of Chemistry has made important progress in the field of electrochemical filter capacitors.
In this study, Qu Liangti's research group reported a new strategy for electric field-enhanced ion migration. By increasing the local electric field intensity, it promotes the internal ion migration rate to reduce the series internal resistance and make up for the shortcomings of the high-frequency characteristics of electrochemical capacitors. Based on a composite active electrode derived from vertically oriented graphene and PEDOT
SS, as well as a narrow channel structure of 5 microns, the area specific capacitance is doubled compared to previous work to 5.2 mF cm -2 . While the frequency performance is equivalent to that of commercial electrolytic capacitors, the specific capacity is improved by two orders of magnitude. Through the femtosecond laser processing method, high-density and high-consistency integration is achieved, which solves the problem of customization of capacitor rated voltage/capacitance. question. In field verification, the capacitor showed excellent filtering performance and circuit compatibility, and even showed excellent stable filtering capabilities for flexible electronic circuits.
This research provides new understanding and design ideas for the development of high-performance electrochemical filter capacitors. The electric field enhances the kinetic behavior of ion migration to achieve a sharp reduction in internal resistance. The research also achieves scalable and high consistency of electrochemical filter capacitors. Chip integration marks an important step towards practical application of electrochemical filter capacitors.
Recently, related research was published in the journal Nature under the title "Ultralow-resistance electrochemical capacitor for integrable line filtering" .
This is just a theory, but I would guess that's because everything in this new sunway one is pure domestic creation. You'll note it's using a custom CPU as well as only using DDR4 memory. All things China makes domestically.
The previous exascale machines probably had foreign components that could be sanctioned. So they decided to hide that information.
This, this is quite an achievement. Kind of kills any "national security" argument US tries to make.

You are probably right about the memory, but some additional information.
This machine was already announced years ago, ~2016
It is already public knowledge, so this is merely more information. Some of the English write ups on it were from visiting academics who have seen the machine.
The development came at a time after US banned exports of higher-end Xeon CPUs and Xeon Phi Compute cards.
It is said to be "domestically designed", but some academics say (and I believe there exists some documentation in Chinese) that is was based on/inspired by the DEC Alpha architecture. Of course, the Alpha's last commercial release development was already 20 years ago, so it's quite justifiable to that.

Cobalt (Co) has the advantages of low resistivity, good thermal stability, and good adhesion to copper (Cu), and can replace tantalum (Ta) as the Cu interconnect structure of integrated circuits (ICs) for technology nodes below 14 nm. new barrier material. Chemical mechanical polishing (CMP) is the only method that can achieve local and global planarization of Cu interconnects, and it is also a key technology that determines the reliability of Co-based Cu interconnect ICs. Citric acid contains hydroxyl groups and has a strong complexing effect on metal ions after ionization, becoming the main complexing agent in Co-based Cu interconnect CMP and post-cleaning. The article reviews the application and research progress of citric acid in Cu interconnect CMP and post-cleaning, including the selectivity ratio of Cu/Co removal rate by citric acid, the surface morphology of Co, and the removal of Co surface residues in Co CMP post-cleaning. Impact, and the development trend of complexing agents and Cu interconnect barrier CMP is prospected.
No its still not submitted to Top500 actually. They still participate in other competitions so capabilities are known. You can see in that slide that the ranking number is empty for Sunway. LUMI is labeled as 2nd in the slide. The companies involved in all 3 known Chinese exascale systems got sanctioned shortly before the news of those systems broke in western media.
