Attempts at merging back into FUNCINPEC
On September 13 and 18, 2019, senior officials of the KNUP and FUNCINPEC began discussion to merge the KNUP back into FUNCINPEC. KNUP spokesman Run Meatra said that senior officials of FUNCINPEC and the KNUP agreed to a merger on December 23, but both never went through with the decision.

On September 22, 2021, both parties discussed merging ahead of the upcoming commune elections. KNUP president Nhek Bun Chhay announced another merger between the two party after they both negotiated several times and resolved their own internal issues. However, due to a controversy regarding the leadership of a united party, the decision to merge never went ahead.
