South Korea's new President Lee Jae Myung and Japanese Prime Minister Shigeru Ishiba vowed to deepen a relationship prized by Washington and closely watched by China and North Korea, as the pair met for their first summit.

President Lee Jae Myung wrapped up Wednesday (June 18) his three-day visit to Canada, where he attended the Group of Seven summit as a guest — a milestone his administration has touted as the restoration of South Korea's summit diplomacy.

South Korea's new president's first move toward easing tensions with North Korea: switch off loudspeakers blaring propaganda and K-pop tunes over the border.
