It's possible to argue the expat benefit package as racial discrimination under the draft law. However, it can be equally argued that HK produce very little local pilots and therefore CX need to use expat package to lure pilots to HK. It depends on how the government defines salaries and benefits. While most western countries consider base salaries and benefits as aggregate, HK government may view them as separate and only cares if the base salaries are equal across all race.
