The United States government acknowledges the existence of the "Secret War" in Laos and dedicates the Laos Memorial in honor of Hmong and other "Secret War" veterans.

The Laotian Civil War was waged between the Communist Pathet Lao and the Royal Lao Government from 23 May 1959 to 2 December 1975. The Kingdom of Laos was a covert theater during the Vietnam War with both sides receiving heavy external support in a proxy war between the global Cold War superpowers. The fighting also involved the North Vietnamese, South Vietnamese, American and Thai armies, both directly and through irregular proxies. The war is known as the Secret War among the American CIA Special Activities Center, and Hmong and Mien veterans of the conflict.

The Hmong and Lao Memorial, or Lao Veterans of America Monument, is a granite monument, bronze plaque and living memorial in Arlington National Cemetery in the US. Dedicated in May 1997, it is located in Section 2 on Grant Avenue between the path to the JFK memorial and the Tomb of the Unknowns, in Arlington National Cemetery, Arlington, Virginia, in the United States. The Laos–Hmong memorial commemorates the veterans of the "Secret War" in Laos who fought against invading Soviet Union-backed North Vietnam Army forces of the People's Army of Vietnam and communist Pathet Lao guerrillas. Approved by the U.S. Department of Defense, Arlington National Cemetery, and the U.S. Department of the Army, but designed and paid for privately by the Lao Veterans of America, Inc., the Lao Veterans of America Institute, and The Centre for Public Policy Analysis, the memorial stands as a tribute to the Hmong, Lao, other ethnic groups, and American clandestine and military advisers who made up the Secret War effort during the Vietnam War. The Lao Veterans of America, Inc. is the nation's largest ethnic Laotian- and Hmong-American veterans organization.

The Hmong people are an indigenous group in East and Southeast Asia. In China, the Hmong people are classified as a sub-group of the Miao people. The modern Hmong reside mainly in Southwestern China and Mainland Southeast Asian countries such as Vietnam, Laos, Thailand, and Myanmar. There are also diaspora communities in the United States, Australia, France, and South America.
