As teams continued to comb areas in Vietnam and Cambodia to search for American POWs/MIAs, Amb. Quinn began to negotiate with the Chinese government to allow them to expand their search. The Chinese allowed teams to look, but an even bigger breakthrough came in the weeks following. After the fall of the Soviet Union, the newly appointed diplomats were more open to sharing information with the outside world. Amb. Quinn and his team asked for access to any Russian records that mentioned the transport of American POWs. The Russian government agreed, and Amb. Quinn and his team quickly headed out to try and piece together the puzzle of the remaining unaccounted Americans.
