Earlier some Chinese scientists discovered a way of making carbohydrates from co2, water and sun light. Now they can even make protein. This could mean they can create abundant supplies of food for the country.
Not a coincidence just keeping a low profile about it China wants to be self sufficient in minerals,energy and food and have long term plans for it, There are even plans for fusion torch recycling and Helium-3 lunar mining

>Helium-3 lunar mining

You should double check how much He-3 is actually on the moon. Despite what space cadets may say, there's extremely little and requires strip mining vast areas ( not depths) for relatively little He-3.

IIRC,the amount is at most .015 g/ton material mined in the sunlit areas and may be as much as .05 g/ton mined in the shadowed. Stress may.

Good points but CLEP is confident about it, Maybe they have figured out a way to do it economically? We would find out by 2050 anyway that's the deadline set by Beijing for establishing SEZ on south pole

It might be a good way to get started and gain experience with space resource extraction. Setting up a logistical chain from earth to moon and back is probably easier than doing it from earth to the asteroid belt and back.

Chinese and American researchers developed gene-therapy for deaf Children.
Five of the six children showed improvement in hearing over the 26-week trial, with four outcomes described by researchers as “robust.” With hearing a critical factor in language acquisition, researchers also measured speech perception — the ability to recognize sound as speech — and all five of those who responded to treatment showed improvement there.

Wireless miniature monitor for oxygen in deep brain tissue:
Chinese scientists have developed a miniature probe that is wireless and dynamically tracks oxygen levels in the deep brain, providing a promising tool for brain disease monitoring.

Summary:
China is currently building the world's most advanced UHV grid. UHV lines are good for carrying power over long distances. The high voltage level reduces line loss. But they are very expensive to build.

China's load centers are in the coastal East and South, while the best wind, solar, and hydro resources are in the North, Northwest, and Southwest. Power (esp. RE) is being generated far from where it's needed most.

UHV lines provide a inter-region backbone to transport power hundreds or thousands of km across the country. The UHVDC lines are used for the longest distances, while UHVAC lines are used for shorter distances, often within the same regional grid.

Yes. China initially got the technology from Siemens I think. I assume they now build it in China proper. China's huge demand for such systems compared to the rest of the world means it has leading engineering know-how in its implementation.
That's kind of the blessing of being China if they would only served their domestic market they already need to pretty much think about global scale scaling issues.
