China achieved 100% localization of spare parts for AP1000 NPPs in Haiyang.
China is progressing to the next stage of its artificial sun/fusion reactor project with BEST expected to start trials in 2027.
We are still pretty far away from it being in real competitive commercial operation.

Two new Chinese reactors recently came under construction, both Hualong 1:
The total starts for China in 2025 is now 7, the highest number since 2010 - before the Fukushima meltdown.
Also - from what I can find (PRIS used to show starts with a slight delay, but hasn't been updating properly this year) - total starts outside China is 3, with one in each of Russia, Korea and Canada.

China achieves breakthrough in key technologies for metal fuel manufacturing..
The China Institute of Atomic Energy (CIAE) officially announced today that, with the support of national and CNNC research projects, the experimental line for the manufacturing principle of metal fuels, led by CIAE, has completed integration and verification at the Huludao base.
Under simulated hot chamber test bench conditions, the project completed the principle verification of three core units: core casting, single rod manufacturing, and component assembly. It achieved several key technological breakthroughs in various aspects such as process flow, key equipment, components, and core materials, effectively improving the technological maturity of metal fuel manufacturing and laying a solid foundation for the engineering verification of integrated fast reactor metal fuel .
China National Nuclear Corporation (CNNC) has successfully developed the complete technological chain for the irradiation and preparation of iodine-131 using enriched target materials.
In the preparation of high-abundance, high-purity tellurium-130 isotopes, the Nuclear Physics and Chemistry Institute has overcome several key technical challenges in isotope separation, oxide synthesis, and purification, successfully preparing ¹³⁰TeO₂ target materials with an abundance exceeding 99% and meeting nuclear-grade purity standards.
Supercritical carbon dioxide (sCO2) turbines have a power to weight ratio similar to jet engines.
An airplane powered by a molten salt nuclear reactor coupled with (sCO2) turbines is in theory possible.
Granted "possible" and "probable" are two different words.
However I believe China eventually will invent the nuclear powered airplane.
But first:
China will build a molten salt nuclear powered ship:

A few comments:
Start of construction is said to be ten years away, pending regulatory approval, infrastructure investment and a customer. Clearly these are long-term projects and they have to start somewhere, but it sounds like this thing is basically at the PowerPoint stage.
Some verbiage in there about this being the first nuclear-powered container ship. Yeah, ok. But it should be acknowledged that the United States, Germany, Japan and the Soviet Union have historically dipped their toes into nuclear-powered civilian cargo ships as well. Russia's Sevmorput was still operating as of 2023, as a container ship no less.
Yet even leaving the specific reactor design aside, this vessel would indeed be noteworthy as by far the largest nuclear-powered ship ever constructed, which neither the linked article nor the originating SCMP piece appears to have noticed. The 25,000 TEU figure given for this PowerPoint ship exceeds that of the largest container ships operating today, the Irina-class ships which are in the 24,000 TEU range. Those ships are ~400m long with a beam of ~60m. If built, this ship would dwarf USS Gerald R. Ford, the future 004 CVN, etc. Comparing the powerplants would be interesting.
