Science by it's nature isn't kept secret, results are shared and verified.

What a second LHC does is allow you to verify results independently. With one LHC you have to be extra careful about assumptions you made and what data might be being thrown off by local peculiarities.

Being at the forefront of particle/energy research is it's own reward. The results are only part of the prize. Learning how to build a LHC is probably just as valuable.

The LHC hosts multiple detector complexes. They are operated independently by different collaborations which compete with each other:

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.
