Japan may abandon a bilateral declaration signed in September with North Korea if Pyongyang continues its provocative missile tests and nuclear program, Chief Cabinet Secretary Yasuo Fukuda said Wednesday.

Under the Pyongyang Declaration, which set a goal of normalizing bilateral relations, North Korea promised to comply with all international agreements on nuclear and missile issues, in addition to maintaining a moratorium on missile launches beyond the previously pledged date of 2003.

When asked whether Japan might abandon the declaration, Fukuda told a regular morning news conference, "Yes, that's right. It depends on how (North Korea) acts."
