Interesting viewpoint - so the fact that Swire Pacific is a HK based company, and has been so for all it's history, it doesn't count as a HK interest? Well, I guess Victor Li is now interested in aviation so could take over - having tried to buy Air Canada - but then again, he is Canadian, so guess they aren't HK interests. Plus his father was born in Shantou, which isn't HK either...
Last time I checked, Swire (UK) stakeholding in Cathay was effectively 13%. This is a lower foreign shareholding than exists in MU or CZ, which allow up to 35% foreign shareholding.
