Joint declaration of summit conference of indo-chinese peoples: Called by Sihanouk and attended by Laotian and Vietnamese communist delegations, the “summit conference” was important mainly for its apparent agreement with Hanoi's position that the war had become an Indochina war and required tighter coordination. The presence of Chou En-lai at the April 25 session was not reported in the declaration. The joint declaration was issued to the press on April 27, 1970 by Sihanouk in Peking; it was also released on the same date in Hanoi, Sam Neua (Laos), and “South Vietnam.” Peking Review, Special Issue (May 8, 1970); excerpts.
