The unconditional return of prisoners of war (POWs) from all the countries of Indochina was, in the words of Henry A. Kissinger, the chief United States negotiator at Paris, "one of the premises on which the United States based its signature of the Vietnam agreement." Kissinger said he had received "categorical assurances" from the North Vietnamese delegation in Paris that United States POWs captured in Laos would be released in the same time frame as those from North Vietnam and South Vietnam, that is, by March 28, 1973.

Under the provisions of Chapter II, Article 5 of the Vientiane Agreement, the two sides were obligated to repatriate all persons held captive regardless of nationality within sixty days of the formation of the coalition government. When the cease-fire came, it was generally assumed that the Pathet Lao held a large number of United States citizens they or the North Vietnamese had captured in Laos, and the Department of Defense listed some 555 United States personnel as unaccounted for--either as POWs, missing in action (MIA) or killed in action/body not recovered. The Pathet Lao had released a number of United States prisoners after the formation of the 1962 coalition. There was considerable uncertainty surrounding the POW/MIA question, however, because the Pathet Lao had neither provided lists of those who had fallen into their hands nor adhered to international conventions on treatment of POWs, in keeping with their contention that the United States was guilty of an aggressive, undeclared war against Laos. Conditions of detention in jungle prison camps were harsh in the extreme, as attested to by the few who managed to escape. Prisoners had no medicine, and they had to supplement their ration of rice, both meager and dirty, with beetles and rats.

Soth Petrasy, permanent representative of the Pathet Lao delegation in Vientiane, told Phone Chantaraj, editor of the Vientiane newspaper Xat Lao (The Lao Nation), five days prior to the signing of the Vientiane Agreement that the Pathet Lao leadership had a detailed accounting of United States prisoners and the locations where they were being held and that they would be released after the cease-fire. He added: "If they were captured in Laos, they will be returned in Laos." On the day the Vientiane Agreement was signed, the United States chargé d'affaires obtained confirmation from Soth of his previous statements and requested further details. Although Soth proposed to send a message to Xam Nua asking for the number and names of United States citizens held captive, this information was not forthcoming.

The United States embassy began pressing for the release by March 28 of prisoners captured in Laos. The question was whether the Pathet Lao would consider themselves bound by the agreement with its implication that they followed the orders of the North Vietnamese. Resolution of the matter was further complicated by the fact that procedures for prisoner exchanges stipulated in the Vientiane Agreement had still to be negotiated by the two sides in Laos.

On March b02 h 26, Soth informed the United States that the Pathet Lao would release eight prisoners in Hanoi on March 28. These prisoners, whose names had previously been given to United States officials by the North Vietnamese in Paris, had been held in North Vietnam for some time. On March 27, the Pathet Lao delivered a note verbale to the United States embassy that stated this fulfilled their POW release obligations and demanded that the United States pressure the Vientiane government to negotiate "seriously" for implementing the political provisions of the agreement. The Pathet Lao rejected subsequent United States requests to dissociate the question of United States POWs from other matters covered by the Vientiane Agreement. The North Vietnamese, for their part, did not respond to Kissinger's requests for clarification of the discrepancy between the number of POWs and MIAs carried by the Department of Defense and the small number of POWs released.

The protocol giving effect to the Vientiane Agreement was signed on September 14, 1973. Paragraph 18 made the two-party Joint Central Commission to Implement the Agreement responsible for implementing provisions for exchanges of prisoners and information. The names of personnel who had died in captivity were to be exchanged within fifteen to thirty days, and all prisoners were to be released within sixty days after formation of the coalition government. However, the only United States citizen released by the Pathet Lao in Laos in accordance with these provisions was a civilian pilot captured after the cease-fire. For the next twenty years, representatives of the new regime would sit at a table and calmly inform visiting United States officials and families of POW/MIAs that they knew nothing about the fate of United States POWs and MIAs in Laos (see Bilateral Relations , ch. 4).
