BEIJING -- Pyongyang may lift its moratorium on missile tests if normalization talks with Japan drag on without any progress, the North Korean Foreign Ministry warned Tuesday.

"Upon learning about the outcome of the talks, the relevant organs and the people of the Democratic People's Republic of Korea are becoming increasingly assertive that it is necessary to reconsider various points related to security, including the nuclear and missile issues, under the untransparent conditions where Japan's words and deeds . . . do not go with each other," the Korean Central News Agency quoted a ministry spokesman as saying.

"Especially, the DPRK's relevant field is of the view that the DPRK should reconsider the moratorium on missile test-firing in case the talks on normalizing relations between the DPRK and Japan get prolonged without making any progress, as was the case with the recent talks," the spokesman said.
