Former US President Richard Nixon told his aides in Vietnam to lie to the public

about US military operations in Cambodia, newly declassified documents show.

"Publicly we say one thing, [but] actually, we do another," Nixon said

in a closed-door meeting with top military aides in the spring of 1970.

His remarks were transcribed for a memo marked "Eyes Only, Top Secret Sensitive."

The 50,000 pages of documents, released in hard copy on November 16, also confirm

that Nixon ordered plans for offensive operations in neutral Laos, as well as a summer

offensive in South Vietnam.
