SEOUL, Feb. 23 (Xinhua) -- South Korean President Moon Jae-in's approval rating rose this week amid eased tensions on the Korean Peninsula, caused by the Democratic People's Republic of Korea (DPRK)'s participation in the Winter Olympics, a survey showed Friday.

According to the Gallup Korea poll, support for Moon was 68 percent this week, up 5 percentage points from two weeks earlier. The third week survey was omitted for the Lunar New Year's holiday.

It was based on a poll of 1,002 voters conducted from Tuesday to Thursday. It had 3.1 percentage points in margin of error with a 95 percent confidence level.

Support for Moon advanced for the past two weeks as the DPRK sent its athletes, cheerleaders and a high-ranking delegation to the South Korea-hosted Winter Olympics, which kicked off on Feb. 9.

Kim Yo Jong, the younger sister of top DPRK leader Kim Jong Un, attended the Winter Olympics' opening ceremony, while Kim Yong Chol, vice chairman of the Central Committee of the ruling Workers' Party of Korea, is scheduled to attend the closing ceremony on Sunday.

The DPRK participation defused tensions on the peninsula, boosting hope for the continued dialogue atmosphere after the end of the Winter Olympics.

Moon's ruling Democratic Party kept its top post with an approval score of 48 percent. It was followed by the main opposition Liberty Korea Party earning 11 percent of support.
