The chairwoman of South Korea's parliamentary committee on foreign affairs said Monday that it is now time to consider a regime change in North Korea.

"It is time to think about all possibilities including some arguments for a change of the North Korean regime," Rep. Na Kyung-won said during an interview with a local radio station.

Na's comments come amid growing concerns over Pyongyang's nuclear and missile programs.

"There should be a consensus whether we should consider the North Korean regime our dialogue partner amid persistent threats," Na said.

The lawmaker also pointed out it was inevitable for the government to suspend the operation of a joint factory park in North Korea. (Yonhap)
