They are operated independently by different collaborations which compete with each other: https://home.cern/science/experiments https://home.cern/science/experiments They just happen to feed off the same particle beams. The proposed Chinese collider would not be a second LHC; it would be a Higgs factory for precision studies rather than a discovery machine like the LHC.
