President Park Geun-hye's job approval rating edged up on the back of public support for her successful visit to the United States last week, a poll showed Monday.

A poll released by polling agency Realmeter showed that 48 percent of people approved of Park's job performance, up 1.2 percentage points from a week earlier.

Those who disapproved came to 4.7 percent, down 2.1 percentage points from a week earlier.

The summit between Park and U.S. President Barack Obama in Washington, D.C. reaffirmed the alliance between the two countries.

Separately, 19.9 percent supported Kim Moo-sung, chairman of the ruling Saenuri Party, as a potential presidential candidate.

Moon Jae-in, head of the main opposition New Politics Alliance for Democracy, came second with 18.6 percent.

The survey was conducted on 2,500 adults on Oct. 12-16 and had a margin of error of plus or minus 2.0 percentage points. (Yonhap)
