On the third day of inter-Korean ministerial talks in Busan, each side will try to coordinate stances through chief and working-level delegates' talks.

In a Wednesday plenary session, South Korea strongly urged the North not to fire any more missiles and return to the six-party nuclear dialogue.

But Pyongyang declined to comment, only saying that its stance was declared on its foreign ministry statement made last Thursday.

The North also stayed quiet on Seoul's call for its return to the six-way talks.

The two sides will continue talks into the night in an effort to narrow such differences.

The Pyongyang delegation will return home Friday morning.
