Military and police intelligence given to the United States and Hong Kong by boat people in 'secret' interrogation sessions could now be used against them. A report, to be delivered this week to the world's senior UN refugee official, says the 11 men face being treated as traitors if they are repatriated to Vietnam. All but one have military or security backgrounds. On arrival in Hong Kong several years ago, they were interviewed up to nine times about US servicemen missing in Vietnam and, in some cases, the internal workings of the military and police. Documents obtained by the South China Morning Post confirm the meetings took place, in particular with staff of the Defence Liaison Office of the United States Consulate. Having been refused refugee status, the men face forced repatriation - a return their lawyers say will almost certainly result in their arrest and persecution. The interviews conducted were lengthy and often conducted over two or three days. The report, to be delivered to the United Nations High Commissioner for Refugees, Sadako Ogata, in Geneva by Hong Kong lawyer Pam Baker, seeks a full review of the cases in the hope they will be given refugee status. It says the Hong Kong Security Branch was interested in interviewing the boat people for 'information on the command structure, communications, internal security, coastal defences and military transportation'. They were summoned to the meetings through the camp public address system and the submission argues the Vietnamese Government is aware the men were interviewed. 'In some cases they did not consider the danger that it would put them in if forced to return as they fully expected not to be returned to the regime they fled,' the submission says. 'The US officials were very secretive about the interviews and in some cases refused requests from our clients for their names and positions.' A Security Branch spokesman confirmed knowledge of the 11 Vietnamese and said the submission was being examined. 'None of the 11 Vietnamese migrants have been selected for early return under the Orderly Repatriation Programme,' the spokesman said. The US Consulate did not respond to a request for comment. China yesterday repeated accusations that Britain was attempting to shift responsibility for the Vietnamese migrants to the post-handover government. In a commentary issued by Xinhua (the New China News Agency), London was urged to solve the problem before the changeover. 'It's the British Government which caused the stranding of Vietnamese migrants in Hong Kong,' it said. 'Both Hong Kong and the British Government should shoulder the responsibility [to repatriate them]. They have no excuse to delay doing so.'
