IBUSUKI, Kagoshima Pref. -- Prime Minister Junichiro Koizumi and South Korean President Roh Moo Hyun said Friday they will seek an early resumption of six-way talks on North Korea's nuclear threat.

During a news conference following their summit at a hot spring resort here, Koizumi said Japan will wait for North Korea to issue further responses on the abduction issue before deciding whether to impose economic sanctions on the reclusive state.

"We will have to see how North Korea responds to demands for the truth. Once we have that, we would then consider what sort of sanctions to impose," Koizumi said.
