On Mar 10, China tested the "high thrust oxyhydrogen rocket engine (大推力氢氧发动机)" in Yungang, Beijing. The engine shut off as planned after running for 520 seconds. [ What's the model number of this engine? ]
This is the second "long running test (长程试车)" of this engine. It is the largest (in thrust) rocket engine developed by China so far. It is used in the "first stage core (芯一级)" of the CZ-5 series.

What China need that Russia can offer is their experience in developing RD-170 or RD-180, not the technology. Technology is a specific design, not the theory. China has the theory, China does not need the specific design because the Russian engines do not fit CZ-9. What Russia can help is some advice when China faces some challenge in developing YF-130, such as high pressure chamber. The help may be just a few words from the past experience, or months of joint investigation. How could that be given a fixed price?
The idea of Russia selling RD 180 or RD-170 are never practical because CZ-9's design in all its evolution variants was never around any Russian engines. RD-180 is too small while RD-170 is too big.
IMO, the idea was like the rumor of Russia tried to get China on board of PAKFA. It never got serious even if it was true, and once China determined what a 4th gen fighter China want, the idea is over for ever.
Russia did want China to get on PAKFA. That’s not a rumor.
Is this their new bomber?
PAK-FA = Su-57 fighter bomber, PAK-DA = stealth bomber, PAK-DP = interceptor, PAK-TA = heavy transport
I would not be surprised if China bought some Su-57 aircraft when it gets to Su-57M upgrade. But this would be at best a limited purchase similar to the Su-35 one. Buying one or two dozen aircraft just for evaluation purposes alone would be useful.
Yet given that Russia is more likely to adopt a cold war footing after this conflict I expect weapon sales of such type to be constrained for a while.
A place where China-Russia cooperation in space would be useful would be the space nuclear propulsion program.
There could also be cooperation in ASAT weapons like A-235 Nudol or S-500. That was kind of cooperation banned with ABM Treaty.
But US cancelled the ABM Treaty.

The space tug would be a great way to ferry crew between Mars and Earth. It is such a rocket punk idea.

Why is a new engine for the first stage needed?
This is not a new engine. It is already in service and used in CZ-5 (IIUC this is what the Chinese text means, quoted below, emphasis mine).

Is the testing a regular feature?
