It was my impression that UKC had revised some of their breed standards to use the FCI standards or simply adopted the FCI standards for new breeds that they accepted.
Here's an announcement about one breed: http://ceb-us.org/the-epagneul-breton/ewExternalFiles/UKC to Adopts Breed Standard Identical to the FCI Breed Standard.pdf
"Work closely" together was probably an overstatement.
