Korea's National Assembly failed to pass revisions to the nuclear security bill this Friday, with the ruling Saenuri Party and the main opposition Democratic Party blaming each other for the hold up.
Ruling party lawmakers are eager to pass a revision to an act that would complete the ratification process for two global treaties on nuclear terrorism and nuclear materials.
DP lawmakers say they will only pass it if the ruling party agrees to pass other pending bills.
If the nuclear security revision isn't approved on Monday, President Park will attend next week's Nuclear Security Summit in The Hague empty handed.
Watchers say it'd be an embarrassment for Korea, which hosted the previous summit two years ago.
