Prime Minister Yoshiro Mori will make a one-day trip to Seoul on May 29 to hold informal talks with South Korean President Kim Dae Jung, Chief Cabinet Secretary Mikio Aoki said Tuesday.

Aoki told a regular press conference that now is "exactly the right time" for Mori and Kim to exchange views, as Japan's policy toward North Korea is at a turning point.

"It is important that Mori establish personal relations with Kim based on trust," Aoki said.
