Chief Cabinet Secretary Shinzo Abe Monday urged North Korea to change its stance on the dispute over its agents' abductions of Japanese citizens and called for a "political decision" by Pyongyang after the two countries failed to make progress on the issue in Sunday's talks.

The top government spokesman said Japan has to see "some progress" on the priority issue in order to be satisfied with the talks now under way in Beijing.

The talks also cover security issues and normalization of diplomatic ties between the two countries.
