Yoon faces tough challenges as new South Korean president

Former top prosecutor Yoon Suk Yeol takes office as South Korea's president on Tuesday, facing a tougher mix of foreign policy and domestic challenges than other recent South Korean leaders encountered at the start of their presidencies.

Yoon's single, five-year term begins at midnight on Monday before he takes the oath of office on Tuesday morning at a formal ceremony in Seoul.

Since winning election in March, Yoon, a conservative who advocates a more hard-line approach toward North Korea, has been denied a honeymoon period.

Surveys show less than 60 per cent of respondents expect he will do well in his presidency, an unusually low figure compared to his predecessors, who mostly received about 80-90 per cent before they entered office.

His approval rating as a president-elect was 41 per cent, according to a survey by Gallup Korea released last week that put outgoing liberal President Moon Jae-in's rating at 45 per cent.

Yoon's low popularity is blamed in part on an acute divide between conservatives and liberals and on contentious policies and Cabinet picks.

Some experts say Yoon, a foreign policy novice, also hasn't shown a clear vision for how to navigate the world's 10th largest economy amid challenges such as North Korea's advancing nuclear arsenal, an intensifying US-China rivalry and pandemic-hit livelihoods.

“Our foreign policy, national security and economy are all in trouble. Yoon should have presented some visions, hopes or leadership to show how he can pull the public together in these difficult times. But I don't think he has shown such things," said Professor Chung Jin-young, a former dean of the Graduate School of Pan-Pacific International Studies at Kyung Hee University.

With US-led nuclear disarmament talks deadlocked, North Korean leader Kim Jong Un recently threatened to use nuclear weapons against his rivals and reportedly is preparing to conduct his first nuclear test in nearly five years.

The US-China confrontation is posing a separate security dilemma for South Korea as it struggles to strike a balance between Washington, its chief military ally, and Beijing, its biggest trading partner.

During his campaign, Yoon accused Moon of tilting too much toward North Korea and China and away from Washington while exploiting ties with Japan, Korea's former colonial ruler, for domestic political purposes.

He has vowed to abandon Moon's appeasement policy toward North Korea, reinforce South Korea's alliance with the United States and improve ties with Japan.

Critics say Yoon's polices will create friction with North Korea and China, although he is likely to strengthen trilateral South Korea-US-Japan security cooperation.

Chung, the professor, said South Korea must accept that it cannot force North Korea to denuclearise or ease the US-China standoff.

He said South Korea must instead focus on strengthening its defence capability and the US alliance to “make North Korea never dare to think about a nuclear attack on us”.

He said South Korea must also prevent ties with Beijing from worsening.

Domestically, some of Yoon's major policies may face an impasse in parliament, which remains controlled by liberal lawmakers until general elections in 2024.

Liberals recently flexed their legislative muscles by passing contentious bills aimed at significantly reducing the investigative rights of state prosecutors.

Critics say the bills are meant to prevent Yoon from investigating possible wrongdoing by the Moon administration.

Yoon must also rebuild South Korea's pandemic response, shaken by a massive omicron surge in recent months.

The COVID-19 crisis has battered an economy already hit by a bleak job market and growing personal debt. Yoon also inherits Moon's economic policy failures that critics say allowed home prices to skyrocket and widen what is one of the worst rich-poor gaps among developed nations.

“The challenges that Yoon has at the start of his presidency are the toughest and the most unfavourable ones” among South Korean presidents elected since the late 1980s, a period viewed as the start of the country's genuine democracy after decades of dictatorship, said Choi Jin, director of the Seoul-based Institute of Presidential Leadership.

Yoon, 61, has invited criticism — even from some of his conservative supporters — over his decision to ditch the mountainside Blue House presidential palace and immediately relocate his offices to the Defence Ministry compound in central Seoul.

Yoon said the move is meant to better communicate with the public, but critics question why he has made it a priority when he has so many other urgent issues to tackle.

Some of Yoon's Cabinet picks have been embroiled in allegations of ethical lapses and misdeeds.

Some experts say a planned trip to Seoul next week by US President Joe Biden is a good opportunity for Yoon to promote public confidence in his leadership, if the two leaders agree on steps that enhance South Korea's national security and economy.
