From May 12-15, the Xuanyuan-1 (玄鸢一号) 20-ton Lox/Kerosene engine developed by CASC successfully completed initial test runs. The engine is the first Chinese low-cost and high-reliability Lox/Kerosene engine, with a sea-level thrust of 13.5 tons and a thrust adjustment capability of 60% to 100%. An annual production rate of 100 units is planned. Further test runs will be carried out from June to October, with 100s/250s/500s reliability runs with a cumulative duration of 3000s. From November to December, six combined power system tests with a total of 1500s will be carried out.
天问一号如何到达火星？揭秘长征五号成功背后惊心动魄的故事 |《你好！火星》 第1集 出发
This is a great video that demonstrates, in a known story, how China got here. This video factually presents the ability and capability of Chinese scientific institutions and engineering organizations in deep-tech/high-tech development. And should I say, this story is not an exception in the modern China.
For those foreigners who are confused of how China has been rising so fast so high, this video is educational. Steal that!
I think the engine is officially/on the surface by Institute of Mechanics, CAS "China Academy of Science" but under the hood by CASC "China Aerospace Science and Technology Corporation". This institute is the one who established the company "CAS Space"/"中科宇航". However, the engine is developed by its subsidiary in Xi'an. So I guess there is large CASC 6th Academy involvement in the engine. After all who else has the competence in liquid rocket engine outside of CASC.From May 12-15, the Xuanyuan-1 (玄鸢一号) 20-ton Lox/Kerosene engine developed by CASC successfully completed initial test runs.

I think this link is about this engine. It is interesting that the engine's is 3D printed, at least the combustion chamber shown in the link. It also worth to note that the nuzzle is made of C-SiC composite.
CAS Space is also developing ZK-1, ZK-1A and ZK-2, all of them are solid rocket. This liquid engine must be for their reusable rocket ZK-3, 4 and 5.

Well they better get the offensive weapon ready

China needs a “hard kill” weapon to destroy Elon Musk’s Starlink satellites, a state university with close links to the country’s communist regime has said.
Researchers from the Beijing Institute of Tracking and Telecommunications Technology called because of its “huge potential for military applications”.
Starlink is Elon Musk’s global connectivity project, consisting of thousands of satellites in a near-Earth orbit paired with ground terminals giving its users high speed internet access.
In a paper published in China’s Modern Defence Technology journal, the five-strong team of academics say Starlink could be used by the US military and called for China to develop weapons to destroy the internet connectivity network. The paper said: “It is necessary to further develop related technologies and form disposal capabilities.”

WTF does this even mean?
Sorry typo, launch was Oct 14, 2021.
Also:
Let's see what microgravity and cosmic radiation did to them.
This is completely nonsensical and a quick path to an uncontrollably escalatory war! There will be tens of thousands of StarLink satellites in orbit once the constellation is complete. Any sort of ability to destroy, damage or degrade it would require a massive investment in disrupting in what is still a private enterprise.
