China's Space Program Thread II

Short and simplified answer, liquid rocket engine is much more difficult to develop than solid engine. I even suspect that many Chinese "private" companies just source their solid boosters from missile producers which PLA is happy to spread out their cost.
Ispace and galactic energy, the ones that have been fucking around with nothing but small solid lift rockets for the last 4 years, are some of the best funded rocket companies in China. Certainly more than newcomers like Orienspace, or Space pioneer. And at least Orienspace is aiming high for their own solid fueled rocket, aiming to be one of the most powerful solid rocket ever launched.

Afterall, this private space companies are supposed to try new things, innovate and try to bring launch costs down. Messing around with tiny little solid rockets isn't a good use of investor's money.

And then there's weird shit like Landspace actually managing to develop a powerful liquid fueled rocket, but they choose to go for a old rocket design that won't allow for reusability, not even allowing them to test it, meaning that they will basically have to design a brand new rocket from scratch to allow them to achieve reusability.

It really is such a waste.

China has officially opened Chang'e-8 lunar exploration mission to international cooperation. Countries and international organizations are invited to submit (experimental) proposals, with submission deadline being December 31, 2023. Final approvals are due September, 2024.

A presentation slide on the construction plan for the International Lunar Research Station. The most intensive construction phase comes in the 2030s, with multiple LM-9 launches planned (the graphic representing the LM-9 is outdated). Also, the slide doesn't show any Russian rockets, so I guess China is going it alone.
