So, it seems that we will have a CZ-7A launch before Tianzhou-4, it is not yet known what it could be, but a satellite would not be far-fetched considering that the CZ-7 already generated confidence thanks to the launch of Tianzhou-2/-3.

Launch date at 23 Nov
Added: It would be a CZ-7A and not a CZ-7.

Mentioned in our China Launch Schedule thread for a long time.

It appears that the launch has been delayed

A Volga-Dnepr Airlines AN-124 flew from Beijing to Haikou on November 3rd followed by a flight back to Beijing on November 8th. Could this be the delivery of the payload for this launch?

Nowhere does it say that anywhere within this video - it only shows trucks that possibly just carried the LM-7A rocket to WSLC from port (which IIRC happened last week). The timing makes this impossible and fits more with the reported late December date.

New fairing for CZ-7A on this one !
Or, well, "new", this one looks like a classic CZ-2F/T / CZ-7 fairing.
(The last picture is from the second CZ-7A flight)
-
I quickly measured with my ruler, it seems to be a 3,35 meter fairing (like the 1st/2nd stage), not a 4,2 meter fairing like the previous CZ-7A fairing, and the CZ-7 / CZ-2F/T fairings. It's not the same fairing as the 3.35m one used on CZ-3A, the tip is not straight, but curved all the way, and it's longer.
Apparently, another new type to add in the long list of Chinese fairings...
(Here is a comparison with the type 3350 of the CZ-3A : )

WENCHANG, Hainan, Dec. 23 (Xinhua) -- China launched a Long March-7A rocket to place two satellites in space on Thursday.
The rocket blasted off at 6:12 p.m. (Beijing Time) at the Wenchang Spacecraft Launch Site in southern Hainan Province and soon sent Shiyan-12 01 and Shiyan-12 02 satellites into preset orbit.
Shiyan means "experiment" in Chinese. Developed by the China Aerospace Science and Technology Corporation, the pair of satellites will do space environment surveys and other related technology tests, the state-owned company said in a statement.
As a modified version of the Long March-7 rocket, the launch vehicle represents the new generation of China's medium-sized high-orbit rocket.
It has three stages and a total length of 60.7 meters, making the Long March-7A the tallest rocket in service in China.
With four 2.25m-diameter additional boosters, the liquid-fueled rocket can send a payload of 7 tonnes to geosynchronous transfer orbit, about 36,000 km above the Earth's equator.
The mission marked the 402nd flight of the Long March carrier rockets.

Shiyan-9 is mainly used for in-orbit verification tests of new technologies such as space environmental monitoring.

According to this commemorative cover both payloads were named Shijian-17-02 and Shijian-17-03 before launch.
