S.Korean President Yoon struggles with low public support one year on

South Korean President Yoon Suk-yeol is hit by low approval ratings after one year as the country's leader.

Since taking office on May 10 last year, the conservative leader has been changing policies of his liberal predecessor Moon Jae-in.

Yoon has been promoting labor and educational reforms and cancelled the policy of reducing dependence on nuclear power.

On the diplomatic front, he is working to help strengthen the United States' "extended deterrence." It refers to the US commitment to defend Seoul and other allies with all its capabilities, including nuclear weapons.

Yoon also resumed leaders' mutual visits with Japan after bilateral relations deteriorated during the previous administration.

He told Cabinet ministers on Tuesday that "there is no area that has seen greater change than foreign policy and security" over the past year.

But on the domestic front little progress has been made on reforms as the largest opposition Democratic Party has a majority in the National Assembly.

The latest opinion poll released on Friday showed that the administration's approval rating stood at 33 percent.

The polling organization says this is the second-lowest figure on the first anniversary of an administration since the 1980s.
