Speaking of reusable Long March 9, Mr. Jiang Jie (姜杰), an academician at CALT, presented a possible technical implementation path for the reusable Long March 9 variants.

This slide is confusing. LEO is 100t while LTO is 50t. A slide in 2023 said that LEO was 150t while LTO was 50t.

The only possible explaination that I can think of is that 100t LEO is in reusable mode in this new slide while 50t LTO is always expandable mode in both slides.

In an CCTV interview around Zhuhai Airshow last November, an expert from CALT said:
First launch of CZ-10A is planned in 2026, and its first launch & recovery test is at the end of 2026. Via a delicate net-tethered hanging recovery approach, we improve the rocket's carrying efficiency. R&D is processed smoothly by now. This schedule will support following lunar missions from 2027 to 2030.

Shan Zhongde, Vice Minister of Industry and Information Technology and Administrator of the China National Space Administration: We are intensively advancing the implementation of heavy-lift launch vehicles with greater thrust, continuing breakthroughs in key technologies and demonstrations for reusable space transportation systems, accelerating the formation of operational launch capabilities, and enhancing our capacity to access space.

The next-generation heavy-lift launch vehicle under development in China is the Long March-9, a Herculean powerhouse among rockets. Boasting formidable thrust, it delivers a low Earth orbit (LEO) payload capacity of approximately 140 tons, making it indispensable for missions such as crewed lunar landings and Mars sample return missions.

Additionally, reusable configurations of the Long March-9 are being further planned. These will significantly reduce the costs of space access and return, improve operational efficiency, and ultimately enable large-scale regularized space transport capabilities. According to reports, the first-stage reusable configuration of the Long March-9 heavy-lift rocket is slated for its maiden flight by 2030, while the two-stage fully reusable configuration is planned for first flight between 2033 and 2035.

The world's largest variable-thrust solid rocket motor... Do you realize how groundbreaking this is?
The U.S. appears to have struggled even with developing 100kg-class variable-thrust solid rocket motors for air-to-air missiles.
The AIM-120D was originally intended to use dual-pulse solid propulsion, but it was later revealed to have abandoned the technology.
This is a massive 5-ton missile motor with 20-ton thrust, capable of serving as the second stage for the DF-2X or the third stage for the DF-31.

More on the Qingzhou spacecraft being developed by Microsatellite Innovation Research Institute. It features a single-cabin design with an internal volume of 27 cubic meters for taikonauts and cargo. It will also have an optional large refrigerator for certain science payloads.

Another image of the mockup. The cargo spacecraft weighs around 5 tons, with a cargo capacity of 1.8 tons going up and 2 tons coming down.

The latest infographic on DeepBlue's Nebula-2 reusable launch vehicle.

Nebula-2 has a diameter of 5m. The 1st stage is powered by 11 Thunder-RS LOX/Kerosene engines, and the 2nd stage is powered by a single Thunder-RSV engine. Nebula-2 has a LEO capacity of 25 tons. The Thunder-RS engine has a ground thrust of 1300kN, vacuum thrust of 1500kN, with a thrust range of 40 to 110% and the number of starts of no less than three.
