Two war-displaced Japanese from China looking for family in Japan met with possible relatives in Tokyo for about two hours Monday but failed to find decisive evidence to determine any definite link, according to Japanese government officials.

Yu Hongjun, 59, met a man from Hokkaido believed to be his uncle, while Xu Lin, 54, met her possible half sister from Saitama Prefecture, the officials at the Health, Labor and Welfare Ministry said, adding that the ages of the two are estimated since they have no birth documents.

The two pairs will undergo blood tests to determine any biological links, a process expected to take several months, the officials said.

Yu and Xu are among a group of 12 war-displaced Japanese from China visiting Japan to search for their relatives. They will stay here until March 14.

The group is on a government-financed program that began in 1981 to enable visits by Japanese separated from their families in the confusion at the end of World War II. Many of the displaced were raised by Chinese foster parents.
