Not only capable, but actually one of many CZ-7's variants was intended to replace CZ-2F, so the design margine is man rated. The also explains partially why CZ-7 isn't so good in payload ratio. CZ-7's LEO 15t was set for that purpose. The larger size of the new generation capsule wasn't the reason to switch to CZ-10A whose reusable LEO capacity is 14t within the 15t parameter. I think the reason is to maintain only one rocket family instead of two to reduce cost.
Yes and no. CZ-10 is previously called CZ-5DY within CASC before the type was approved for development. Actually all current CZ rockets CZ-5, CZ-6, CZ-7 and CZ-8 were CZ-5XXX in early studies, but got different numbers later on. CZ-5 was envisioned to be a family. From the perspective of technical root, all are CZ-5 variants, from administrative perspective, they are different rockets.
LandSpace has completed the final assembly of the YQ-10 auxiliary propulsion system for the second batch of ZQ-2 launch vehicles. The auxiliary propulsion system is used to control the roll, pitch and yaw of ZQ-2's second stage. YQ-10 will now undergo hot fire tests.
