South Korea's new president Lee Jae-myung pledges to 'unite' country

Just hours after winning the South Korean presidency, Lee Jae-myung has pledged to "unite the people" in his inauguration speech on Wednesday, BBC reported.

The 61-year-old won a snap election by 49.4% - a clear rejection of his rival, Kim Moon-soo, who came from the same party as impeached president Yoon Suk Yeol.

Yoon triggered months of political chaos after he attempted to impose martial law, which eventually resulted in his impeachment.

As he takes on the top job, Lee now faces the daunting task of not only uniting the country, but also balancing ties with its most important ally, the US, under President Trump's unpredictable brand of diplomacy, according to BBC.
