Xingkong-2 hypersonic aircraft (Starry Sky-2)

"Launched in a rocket, the waverider was released in the air after about 10 minutes. "
"It flew independently, made large-angle turning maneuvers, and landed in the targeted area as planned.
The flight vehicle reached 30 kilometers in altitude at Mach 5.5-6, the academy said."

VPN is not available now, so not sure if I found the correct image of Xingkong2.

It is so small. I think it is close to B611 short range missile. A cooperation project between CASIC and Turkish MKEK. Its diameter is about 0.6 meter. Max range is about 200 km. Warhead mass is reportedly 480 Kg. A truck can carry two of some later version, in box-like containers, which is visible in the Xingkong2 image.

China to launch Long March-9 rocket in 2028
BEIJING, Sept. 18 (Xinhua) -- China plans to launch the heavy-lift carrier rocket Long March-9 in 2028, said an official of China National Space Administration (CNSA) at the World Conference on Science Literacy 2018 on Tuesday.
Li Guoping, director of the Department of System Engineering of the CNSA, said that the length of the Long March-9 will exceed 90 meters, and the rocket would have a core stage with a diameter of 10 meters.
It would be able to carry a payload of 140 tonnes into low-Earth orbit, five times that of the Long March-5, said Li.
The rocket's capacity would also reach 50 tonnes for Earth-Moon transfer orbit.
China is also developing a medium space rocket, the Long March-8, which is expected to make its maiden flight in 2020.
The Long March rocket series have been launched 284 times, sending more than 400 spacecraft into space.

They also cloned their version of the gridfins.

Of course do they have the software to actually recovered and landed a booster core? Otherwise the Long March 6X is just vaporware.

For now.  Don't underestimate engineers that have been shown something can be done.  SpaceX may not be handing out engineering drawings for the Falcon, but they haven't exactly been keeping everything top secret either.  And Musk is quite likely to say, "Bring it on!" with regards to competition.

If a moderator sees this comment ..... it would be very useful to have this thread split into separate threads for the differing CZ-9, CZ-8, etc vehicles please.

2 * yf-100 + 2 * yf-115 on first stage of CZ-6X
the thrust of yf-115 is 18 tonnes, they are used for vertical landing(the proposal was submitted on 2014)

The basic software the land a booster like Spacex has been around since the 1990s in DCX so it's likely they're familiar with the algorithms used.
The biggest issue would be having a way for the booster to throttle down enough to be able to be landed in that manner.
Spacex lucked out a bit on their nine engine design that it allows 1 to 3 engines to be used during boost back and landing so they only need a throttle range down to 40% vs trying to get an engine to throttle down to 10%.

Though some of the other concepts they showed such as the swing wing could work with existing engines.

Engineer: SpaceX has Done it! It can be done!

then

China improves Long March-6 rocket for growing commercial launches
Quote
BEIJING, Feb. 11 (Xinhua) -- China announced Monday that it is developing the modified version of the Long March-6 rocket with four additional solid boosters to increase its carrying capacity.
The improved medium-left carrier rocket will be sent into space by 2020, according to the Shanghai Academy of Spaceflight Technology under the China Aerospace Science and Technology Corporation (CASTC), which designed the rocket.
With a short launch preparation cycle, the Long March-6 has been mainly used for the academy's commercial launches. The rocket completed two space tests in September 2015 and November 2017, carrying 20 satellites and three satellites, respectively.
The three-stage rocket is 29.3 meters long, with a launch weight of 103 tonnes. It has a carrying capacity of one tonne for sun-synchronous orbit.
Fueled by a liquid propellant made of liquid oxygen and kerosene, the Long March-6 is China's first carrier rocket that uses non-toxic and non-polluting fuel.
Ding Xiufeng, executive manager of the Long March-6 project, said in response to the growing demand for commercial launches, they will have the rockets' market competitiveness enhanced through technical improvements, so that they can provide easier, faster and more comprehensive services to users at home and abroad.
In January, the China Great Wall Industry Corporation, affiliated with the CASTC, signed a multiple launch services agreement with Satellogic to use the Long March-6 and the Long March-2 rockets to launch 90 satellites for a private Argentine company in the coming years.
The first 13 satellites will be delivered later this year. It will be the first time for the Long March-6 to provide launch services for an international user.

This is the solid fuelled variant of planned CZ-6A launcher.
