For those who aren't familiar with new Chinese rockets, the Long March 7A is more or less the LM-7 topped by the existing liquid hydrogen 3rd stage of the LM-3A/B/C series. At 7 tonnes to GTO, it will be China's next mainstay EELV-Medium class rocket.https://twitter.com/AJ_FI/status/1211659308716494848 …
2 other new variants of the LM-5/6/7 series - both of the "Soyuz-Antares-Falcon 9 RTLS class" (ahem) - are probably also flying by next year. The Long March 6A - a LM-6 w/stretched 1st stage & 2 engines + 4 2-meter-diameter SRBs, can lift 4 tonnes to a 700 km high SSO.
The Long March 8 - with LM-7's 1st stage, 2 of LM-7's boosters and the existing LM-3A/B/C's 3rd stage as its 2nd stage - lifts 5 tonnes to SSO and 2.8 tonnes to GTO.
Interestingly it's these 2 variants that can bring reusable rockets to the Chinese The LM-8's design was in fact drastically changed from using SRBs to LRBs for consideration of using the LRBs to land the 1st stage+LRBs in one piece!
Also under consideration is a LM-6-derived core only rocket where the LM-6A 1st stage would get 2 extra engines (perhaps the LM-6 2nd stage's YF-115) for landing the 1st stage.
