Japan has requested that Pyongyang provide full answers to 150 questions about the fate of 10 Japanese citizens whom Tokyo believes were abducted to the North, government sources said Friday.

During their two-day working-level talks in Beijing that ended Thursday, Japan gave the list of questions to North Korea. It hopes to receive Pyongyang's answers at the next round of working-level talks, which Japan has suggested for September, the sources said.

The list is similar to one given to North Korea during negotiations on normalizing bilateral ties, held in October 2002 in Kuala Lumpur, they said.
