Yes.it's racist,I agreed it,but there must be reason for being racist.In my experience,I worked in other MNC company before,worked together with Chinese & non-Chinese(Malay/India),One thing I found between my teammate.
Chinese,you asked to do one thing,he will do and suggest better improvement.
Non-Chinese,you asked to do one thing,he will do for it,once done he will not tell you done already,until you ask him.Bro,done already?Oh ya.already.sweating.
I have alot non-Chinese friends and colleague too,some of the really smart and hardworking.But,wondering why majority or High Percentage of Non-Chinese always giving disappointing feel,always have problem is laziness,MC always.really curious.this might be reason ,some employer stated the statement Chinese ONLY,although I am not agreed with it and it's racist.
