The news Sunday of North Korean leader Kim Jong Un's interest in holding a summit with Prime Minister Shinzo Abe offered a glimmer of hope to the relatives of Japanese nationals kidnapped by North Korea decades ago.

"The fact that Prime Minister Abe and Kim Jong Un are both looking for talks is the clearest and most promising development we have seen so far," said Sakie Yokota, the 82-year-old mother of Megumi, who was abducted in 1977 at the age of 13.

"Things are finally moving forward and I hope they go well," she added.
