CZ's business class across the pacific is on their 777 from LAX to CAN and it is about as good as EVA's economy deluxe product. I would never willingly fly this again after flying on this plane from CAN to PEK in biz class I was very upset that I paid the extra 100 bucks for upgrading myself because their C class is horrible on the 777.

That being said they do have lie flat seats installed on business class on the A330 that they fly from CAN-AMS so perhaps they are going to be getting better soon. I'm sure their service will still stink though, after all it is mainland china!
