is it possible to boycott "made in china" ?

You can always choose not to buy goods produced in China if you find out that they are made there. not all products have their country of origin shown and i would point out china is now a world leader in some very good initiatives. check your facts are up to date before you condemn and bear in mind it's usually the inhabitants of a place who suffer more than the government when embargos, boycotts etc are used.

Sure you can. You can live the life of the uni-bomber.

A strange question in the era of WTO.

Sure you can. When you have a choice, for higher price items such as computer, digital camera, cell phone, appliances, cars, car parts, etc., you pay special attention to products country of origin. You could do it starting by yourself, and with your family members.

And because the labor costs, land use costs, and other costs are rising in PRC China; very soon, the manufacturing will be moved out to other South East Asia countries like Vietnam, Laos, etc.

On a personal level you can , but it will be of zero value .
Too late now .

Certainly. You are free to buy, or not to buy, anything you wish. Look for the label on any item and make your choice. It is your money to spend or not to spend as you choose.

You can be pretty effective in determining where products come from, as an individual. Certainly, you can't identify the origins of every product, since parts of every manufactured goods have international origins. Give it a try, though. I read labels carefully. The current issue of Consumer Reports magazine covers this very topic in depth.
