I dont have a particular dislike for Chinese people ..some of my best friends are owners/cooks at my favourite cafes.I dont where you are from but I am a 66 yesr old Australian and in these parts the abbreviation for Chinese people is commonly used and is not derogatory.
Good point about what the Chinese have done to Sianookville in Cambodia. I went there about 12 years ago and it was quiet little town with lovely beaches and cheap hotels and food.From what I have learnt the Chings have totally destroyed it.I dont think I want to ever go back there again.
DINNO is right when coming into Australia you must declare any food,plants seeds etc that you have even if you think it might be o.k. They will tell you if you can keep or they confiscate,no problems or penalty.
