     [1] World Consumer Rights  Day is celebrated annually by consumer organizations worldwide. It

commemorates the historic declaration on March 15,1962 by John F.Kennedy,the former US President,

of the basic Rights of consumers,which include: "the right to  safety","the right to be informed","the right to

choose",and "the right to be heard".

     [2]This_declaration_has_led_to_international_recognition_by_governments_and_the_United_Nations_

that_all_citizens,regardless of their_incomes_or_social_standing,have_certain_basic Rights_as_consumers.Officially,World Consumer Rights Day was first observed on March 15,1983 and has since become an

important occasion for mobilizing citizen action,with recognition of consumer rights taking off around the

world.On April 9,1985,the United Nations Assembly General Assembly adopted the UN Guidelines for

Consumer Protection that provide a framework for strengthening national consumer protection policies

around the world.

     [3] The  guidelines included  Kennedy's  four basic consumer rights plus another four:  the right to

satisfaction of basic needs;the right to redress (赔偿);the right to education;and the right to a healthy

environment.Currently,the fundamental consumer rights are recognized globally.

     [4]World Consumer Rights Day normally has a theme associated with an activity or development that is

relevant to consumers. Whatever their objectives, they share the same underlying aim of  bringing about

important and needed benefits for consumers.

     [5] In recent years, progress has been made for recognition and protection of  consumer rights in

developing countries.At least,March 15 is a day when consumers are filled with pride and satisfaction.

However,there are many reports on violation of consumer rights by unethical  marketing practices.
