Why don't you buy anything chinese?
Me - Nestle, Walmart, Primark, plastic bags, over packaged products, cheap plastic toys and tat
try to buy fair trade where possible, or otherwise clothes from companies which at least have an ethical policy of some sort (if you ask for it, they will either email you an ethical policy, or make an excuse about why they don't have one)
Fair trade food where possible.
try to buy sustainable wod products
try to buy organic cotton.
It is a pain though, as so often you can't find a fair trade version - eg, kids socks and undies.
But hopefully market forces will move this along within the next few years.
