Orbit is resource like land and water on earth. Elon Musk on behalf of US is claiming that resource at the expense of other countries. So yes, China should do the same even if we just throw some bricks or rocks into those orbits.
China's Space Program Thread II

China will drop it if America drops it (and deorbits existing Starlink satellites). Maybe.
I think the slides refer to the CZ-3B (长三乙) which is the 4-booster model taking the place of CZ-7 for the Venus mission. 3C is the one that only has 2 boosters with a lighter payload allowance.Two slides on China's Venus exploration program. Instead of firing her engines to slow down in order to enter a stable orbit, the spacecraft will use the atmosphere of Venus as a brake to achieve the necessary speed reduction. This will save some 415kg of fuel, which in turn allows the probe to be launched using the smaller Long March 3C rocket, as opposed to the larger and more expensive Long March 7.

That was a typo. Thanks for the correction.

This is a pretty big deal for China's development of space nuclear power and space nuclear propulsion.
China has successfully demonstrated a 100kW closed-loop thermal-electric conversion system that uses helium-xenon as the working fluid. Basically, a nuclear reactor heats and expands the working fluid, which then passes over a turbine to generate mechanical energy, which is then used to generate electricity.
The first image below shows the turbine. The second image illustrates the closed-loop Brayton cycle design.

A minor update. The Xuntian space telescope is scheduled to be launched by the end of 2024, according to the project chief Liu Chao (刘超) at a recent presentation. The launch had been planned for 2024 since the early days, but for a time it was reported that the launch would be moved up to 2023, and now the it has been returned to the original plan.
