Chinese State Admin. of Sci. Tech. & Ind. for National Defense, supervising CNSA, published amendments of regulation of commercial launch licenses including one that requires deorbiting upper stages. Great news if that means the next Long March 5B core stage will be suborbital

Link to the amendments: http://gfplatform.cnsa.gov.cn/n4235/c6841957/content.html
It also requires submission of deorbiting plan of spacecrafts in the application of launch license

Well, the amendments may or may not apply to the next Long March 5B launch, depending on how the administration defines "commercial" or if the launch of Chinese "Starlinks" is categorized as "commercial".

A presentation by Haiyang government shows 6+ sea launches of 4 different rockets are planned in 2023.
They are Smart Dragon 3, Long March 11, GALACTIC-ENERGY's CERES-1 (first) and ORIENSPACE's Gravitation-1 (first)

GALACTIC-ENERGY's CERES-1 (first) is wrong, now it will be 6th! it might be Pallas-1.

Note that on the electronic display screen used in Li's factory visit, one could see that Galaxy Space seems to have built a prototype of the "Chinese Starlink" satellite, AND explicitly says that it and roll-able solar panels used on their LEO comsat prototypes are built "with reference to SpaceX Starlink".

The company previously launched 6 LEO comsat prototypes in March 2022 that looks pretty much like the OneWeb satellites.

A glimpse of China's interstellar probe
Quote
the two Chinese interstellar probes, which seem nuclear powered, to the nose and tail regions of heliosphere have got a name: 神梭 Shensuo (梭 means the shuttle). Waiting for a replay of the lecture by CAS chief scientist WANG Chi to see more details

Wait have I seen this somewhere before :o
In Boca China?
The Chinese are wonderful followers.  Show them how to do something, and they will figure out how to do it better.  The Japanese were very good at doing that, too, back in the day.
Japanese do it better ie more reliable. Chinese do it cheaper and quite often less reliable.

Can you elaborate on "reliable"? I agree that the Chinese are doing it more slowly but it is definitely reliable. Compare the success rate of China and Japan in terms of rocket launches and Solar System exploration.

Just as with Japan, China can do both. It all depends on your budget: buy cheap, get cheap. Buy quality, get quality. Foxconn can pump out flimsy plastic chintz or Macbooks and iPhones.

China's science missions have clearly had sufficient budget thus far. Beating the Mars Curse on the first attempt with a combined orbiter/lander/rover is no mean feat, neither is lunar farside landing and operations, or LOR sample-return (and post-mission gravitational assists and cislunar tour to DRO).

I was referring to consumer products in general. China's government space program is well funded and doesn't seem to cut corners.

"China made its ambitions for expanding the country’s presence in space clear on Monday, when Lin Xiqiang, deputy director of the China Manned Space Agency, set a 2030 time frame for doing the same and laid out plans for scientific and technical research there, officially confirming that a previous timeline of landing astronauts on the moon after 2030 had been brought forward."

Yes, the author wasn't aware that the Tiangong-3 space station design was dropped in the mid-2010s because the CNSA's goals for the Tiangong-2 and Tiangong-3 were merged.

Prior to the start of CSS construction, China officially presented its future station as "Tiangong" (without the additional designation of 1, 2 or 3). But once this construction had started, the name "Tiangong" stopped appearing in official communications. And even the name seems to have disappeared completely. So I don't know how it really is with this "Tiangong". :(

The China space program is far more advanced than most people realize
China's lunar base is not much smaller than the Artemis plan. However, it is difficult for anyone to feel it before 2035. 2035, 2045 are two crucial milestones.

The Chinese space industry before 2035 is completely different from that after 2035. Before 2035, they were all catching up with the United States, and after 2035, they were basically catching up with the United States.

The current Chinese manned lunar landing program is at the Apollo level, with a total mission mass of LTO 50t.

Not comparable to the specifications of Artemis 5 (60-70 ton scale), this is actually similar to the scale of the constellation's planned lunar landing.
