Russia conducts regular, very visible joint exercises with the PLAN in the western Pacific with their Pacific Fleet. Russia and the PLAN conducted very impressive exercises again this year.
Once the Liaoning is ready for it...and that will not be until her airwing is worked up, trained, and operating...in another 2-3 years at least, I am pretty sure she will be involved with those exercises.
When that happens, I would not be surprised in the least to see the Kuznetzov come over and join the party.
As I say, the two could meet up whenever the Liaoning starts making voyages to more distant places too...so I believe the two will in fact get together at some point.
Time will tell.
