The National Assembly is set to hold a plenary session Monday to deal with contentious issues, including a resolution on the April inter-Korean summit.

The final plenary meeting of the current extraordinary session is scheduled to open at 2 p.m., which will cap the first half of the 20th National Assembly's four-year term.

Rival parties are expected to clash over the proposed resolution supporting the Panmunjom Declaration adopted by President Moon Jae-in and North Korean leader Kim Jong-un after their summit on April 27 at the truce village of Panmunjom.

The two leaders agreed to seek "complete" denuclearization of the Korean Peninsula and pursue an end to the 1950-53 Korean War.

Moon and Kim held a surprise second summit on Saturday. The North's leader has reaffirmed his willingness to denuclearize and meet US President Donald Trump, Moon told a press briefing Sunday.

Rival parties earlier agreed to handle the resolution at Monday's session, but it is unclear whether it could be put to vote due to opposition parties' objections.

The ruling Democratic Party welcomed the leaders' meetings, but the main opposition Liberty Korea Party denounced the talks for failing to confirm North Korea's sincere willingness to completely dismantle its nuclear program.

"The second summit was held out of desperation as we could not miss a chance for peace on the Korean Peninsula," said Hong Young-pyo, the floor leader of the DP, stressing that parliament should lend support to Moon's peace efforts.

"Inter-Korean relations appear to be on a roller coaster, but in reality, they are on a bullet train," Hong said. "If the US-North Korea summit becomes a success, the Korean Peninsula will stand at the starting point of peace and prosperity."

National Assembly Speaker Chung Sye-kyun said he will make a last-ditch effort to persuade lawmakers to pass the resolution later in the day.

"If parliament does not express its stance toward the critical issue, it effectively neglects its duty. I really hope for the passage and will do my part for that," Chung said at a press conference marking the completion of his two-year term.

Meanwhile, the legislation and judiciary committee will review about 200 pending bills in the morning before the plenary session.

The motions include proposals aimed at transferring water management affairs handled by Seoul's land ministry to the environment ministry.

It will also deliberate on a revised wage bill that counts some regular bonuses and welfare allowances as minimum wage. It is uncertain whether the motion will be approved due to objections from some opposition parties. (Yonhap)
