Close enough. KA actually had two L1011's leased from CX in the end. CX bought the last one specifically to lease to KA and I think it was the addition of the second one that triggered the conversion of KA crews to the L1011 per their pilots association agreement.
One of the claimed reasons for transfering SHA to KA was CX was perceived by the Chinese as a British carrier because Swire was ultimately British and the UK bilateral only allowed one British operator to serve China which was by BA flying to BEJ. Although they allowed CX to operate to SHA there were great difficulties expanding the service and most flights were only allowed as charters masquerading as scheduled flights requiring frequent reapplications to the Chinese authorities. It was thought that transfering to KA, which was seen as more a HK airline, would overcome these difficulties.
