The briefing came as the U.S., South Korean and Japanese navies staged joint tactical drills on Wednesday in waters between the Asian neighbours.
A Japanese escort vessel and U.S. and South Korean destroyers joined the training aimed at stepping up trilateral ballistic missile responses, Tokyo's defence ministry said.
Youn Kun-young, another member of the committee, said North Korea might also develop solid fuel-based ICBMs this year, and confirmed the defence ministry's report that Chinese spy balloons did not enter South Korean airspace.
