Models of Long March 12 and reusable Long March 12B launch vehicles, the latter of which is under active development. The second image shows a slide presented by CASC on a certain new reusable rocket in the 4-meter-diameter class. I think it's referring to the Long March 12B. If so, 12B is a bit thicker than 12, which has a diameter of 3.8m
The reusable Long March 12A project is proceeding along. A 75-km VTVL test will be conducted next month. The first two images show the launchpad being prepped for the test.
The Long March 12A VTVL test vehicle has arrived at Haiyang Oriental Spaceport. The vehicle will be used in the upcoming 75km VTVL test.
