SEOUL, South Korean parties evaluated Tuesday that the historic summit between the United States and North Korea will have a limited impact on the upcoming local elections.

North Korean leader Kim Jong-un expressed "firm and unwavering" commitment to "complete denuclearization of the Korean Peninsula," in a joint statement adopted after a summit with U.S. President Donald Trump.

The unprecedented summit was held just one day before the local elections and parliamentary by-elections, making rival parties skittish about the event's impact on the polls.

The ruling Democratic Party (DP) and other smaller liberal parties expressed their optimism for the summit on hopes that it could set the tone for peace on the peninsula.

"Issues over the Korean Peninsula have been already factored in the elections as rapprochement following an inter-Korean summit in April has extended into now," said Park Beom-kye, the DP's spokesman.

The governing party hopes that the U.S.-North Korea summit may have a positive impact on undecided voters.

Pre-election polls showed that the DP is widely expected to clinch a sweeping victory.

"We expect that the peace atmosphere may affect undecided voters in areas bordering North Korea where the rapprochement could open chances for economic benefits for them," it said.

The main opposition Liberty Korea Party (LKP) and other minor opposition parties said the summit will have limited impact on the elections.

The LKP has highlighted the need for an agreement on North Korea's complete, verifiable and irreversible denuclearization (CVID).

"The U.S.-North Korea summit is the summit. The local elections are the elections," said Kim Sung-tae, the floor leader of the LKP.
