Lee faces the most daunting set of challenges for a South Korean leader in nearly three decades, ranging from healing a country scarred by the martial law attempt to tackling unpredictable U.S. protectionist moves.

South Korea woke on Wednesday to a new liberal president, Lee Jae-myung, who vowed to raise the country from the turmoil of a martial law crisis and revive an economy reeling from slowing growth and the threat of global protectionism.

The election is set to end months of leadership tumult that have followed the country’s short-lived imposition of martial law.
