(CNN) When North Korean leader Kim Jong Un and his South Korea counterpart, Moon Jae-in, meet next Friday, the most important topic on the agenda is the one on which there has been least clarity: denuclearization. South Korean officials and Chinese state media have said Kim is willing to discuss denuclearization on the Korean Peninsula. But North Korea for decades has been pushing a concept of "denuclearization" that bears no resemblance to the American definition, vowing to pursue nuclear development unless Washington removes its troops from the Korean Peninsula and the nuclear umbrella defending South Korea and Japan. "We welcome it as a forward-looking move... but an important thing is whether the move will lead to the complete abandonment of missile and nuclear developments in a verifiable and irreversible manner," Abe told reporters.
Japanese Prime Minister Shinzō Abe praises North Korea's statement that it would suspend nuclear and missile tests, but he also states the results must lead to verifiable denuclearization.
