Groups of ethnic Korean residents in the United States are planning to establish a memorial in observance of the Korean women who served as sex slaves for the Japanese army during World War Two.

The groups played a leading role in the U.S. Congress’ adoption of a resolution on the so-called "comfort women" two years ago.

Similar to the numerous tablets set up across the U.S. to memorialize the victims of the Nazi Holocaust, the Korean groups are seeking the building of the memorial to let the world know that wartime sex slavery violates basic human rights and must never again occur.

Meanwhile, the Korean American Voters' Council has decided to build memorials in Flushing, New York, and Bergen County, New Jersey.
