The exchanges between the three cities of Yangzhou, Jiangsu (China), Karatsu, Saga (Japan), and Yeosu, South Jeolla (Korea) began when Yangzhou and Karatsu became friendship cities in February 1982, and Karatsu and Yeosu reached a sister cities agreement in March of the same year. In 1993, the three cities’ mayors held a meeting, leading Yangzhou and Yeosu to tie a friendship exchange agreement in 1995, completing the trilateral exchange mechanism.
Based on this relationship, the three cities have hosted the CJK Sister/ Friendship Cities Go (board game) Exchange Tournament since 1999. This case is one of the longest standing trilateral local exchange programs.
Yangzhou was selected for the CCEA 2020 with Kitakyushu (Japan) and Suncheon (Korea).
