HANOI, Vietnam—Vietnam and the United States have finished the cleanup of dioxin contamination at Danang airport caused by the transport and storage of the herbicide Agent Orange during the Vietnam War.

The 30 hectares (74 acres) of land cleansed of the toxic chemical were handed over to Vietnam at a ceremony Nov. 7 where Vice Defense Minister Nguyen Chi Vinh praised the U.S. government’s involvement in the cleanup.
