Overview

  • In Tokyo, President Lee Jae Myung and Prime Minister Shigeru Ishiba reaffirmed the goal of complete denuclearization of the Korean Peninsula and closer coordination with the United States.
  • The two leaders said they will issue a joint statement for the first time in 17 years and establish a joint consultative body to address shared challenges.
  • Lee’s decision to visit Japan before Washington is designed to strengthen trilateral alignment before his Aug. 25 White House meeting with President Donald Trump.
