After the two-day meeting between the Asian nations, South Korean sports minister Cho Yoon-sun announced the "PyeongChang Declaration", under which the countries agreed to expand their sports exchange and cooperation, and sought their counterparts' expertise to ensure the smooth running of the Olympics.
"For the success of PyeongChang 2018, Tokyo 2020 and Beijing 2022, the three nations will share their know-how and undertake joint efforts to create excitement for the events," the declaration read.
"Through sports exchanges, South Korea, China and Japan will strengthen mutual understanding and trust, and will use that as a base for peaceful co-existence in Northeast Asia."
The neighbours will also seek to step up anti-doping efforts and agreed to create an "Olympic Legacy".
"South Korea, China and Japan are the oldest neighbours in the world, and we've all established brilliant and unique civilizations on common ideological and cultural foundation," Cho was quoted as saying by the Yonhap news agency.
"In addition to the success of the Olympics in the region, I hope this sports ministers' meeting will offer a vision for the future that can bring about the co-prosperity of the three countries."
