South Korea’s new President Lee Jae-myung vowed on Wednesday to restart dormant talks with North Korea and bolster a trilateral partnership with the US and Japan, as he laid out key policy goals for his single, five-year term.

Lee, who rose from childhood poverty to become South Korea’s leading liberal politician vowing to fight inequality and corruption, formally began his term earlier on Wednesday, a day after winning a snap election that was triggered in April by the removal of then-President Yoon Suk Yeol over his ill-fated imposition of martial law late last year.

In his inaugural address at the National Assembly, Lee said that his government will deal with potential North Korean aggression with “strong deterrence” based on the solid South Korea-US military alliance. But he said he would “open a communication channel with North Korea and establish peace on the Korean Peninsula through talks and cooperation.”
