Samsung Electronics Vice Chairman Lee Jae-yong will serve as a presidential envoy for the nation's bid to host the 2030 World Expo in the southeastern port city of Busan.

According to the top office on Thursday, Lee will be sent overseas to promote the city’s bid.

There is speculation that Lee is working on arranging a meeting with British foreign secretary Liz Truss, who is widely expected to take office as prime minister next Monday, but no schedule has been confirmed.

Speaking to reporters earlier this week, Prime Minister Han Duck-soo said the Samsung heir is expected to visit a number of European countries close to the upcoming Chuseok Thanksgiving holiday to promote the bid.

SK Group Chairman Chey Tae-won is also expected to visit Japan this month to campaign on Busan’s behalf, where he will potentially meet with Japanese Prime Minister Fumio Kishida and visit Osaka, the host city for the 2025 Expo.
