The National Assembly is set to hold a plenary session Monday to deal with controversial 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 U.S. 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 (DP) welcomed the leaders' meetings, but the main opposition Liberty Korea Party (LKP) denounced the talks for failing to confirm North Korea's sincere willingness to completely dismantle its nuclear program.
Meanwhile, the legislation and judiciary committee will review about 200 pending bills in the morning before the plenary session.
The motions include a proposal 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)
