SASEBO NAVAL BASE, Japan — A Joint POW/MIA Accounting Command team has concluded a preliminary trip to Myanmar, where they are planning investigations for potential recovery operations later this year.

The five-person planning team met with government and U.S. Embassy officials to coordinate operational, logistical, transportation, communications and medical issues for the operations, a JPAC statement said Tuesday. The team also met with local historians and people associated with research and archival resources on World War II.

About 730 Americans remain unaccounted for in Myanmar from the war, the statement said. JPAC officials last performed recovery operations in the country eight years ago.

Relations between the United States and the country, also known as Burma, have improved during the Obama administration. The country’s ruling military authority has instituted some reforms and tried to distance itself from North Korea, moves that have been met by cautious engagement.
