SEOUL, March 15 (Xinhua) -- South Korean President Moon Jae-in's approval rating jumped this week on the agreed summits between South Korea and the Democratic People's Republic of Korea (DPRK) and between the DPRK and the United States, a poll showed Thursday.

According to the Realmeter survey, support for Moon was 69.2 percent this week, up 3.4 percentage points from a week earlier.

The result was based on a poll of 1,502 voters conducted from Monday to Wednesday. It had 2.5 percentage points in margin of error with a 95 percent confidence level.

The rapid increase in Moon's support score came as Moon's special envoys visited Pyongyang and Washington last week, helping bring about the agreements to hold the inter-Korean summit in late April and the DPRK-U.S. summit by May.

The positive agreements were reflected in Moon's support rate belatedly as some liberal politicians were embroiled in sex abuse scandals last week.

The pollster said public opinion spread that the sex abuse is happening in the entire society, not in the liberal bloc alone.

Moon's ruling liberal Democratic Party garnered 51.5 percent of support this week, up 3.4 percentage points from the previous week.

Support for the main opposition Liberty Korea Party fell 0.3 percentage points to 18.9 percent, keeping a downward trend for the second consecutive week. The minor conservative Bareun Future Party's support dipped 1 percentage point to 7.4 percent.

Approval scores for the minor progressive Justice Party and the minor liberal Party for Democracy and Peace stood at 4.8 percent and 2.8 percent respectively.
