China and South Korea say they're looking to expand cooperation ahead of the 30th anniversary of their diplomatic ties next year. This comes as Chinese Foreign Minister Wang Yi met with South Korean President Moon Jae-in and Foreign Minister Chung Euiyong in Seoul. It is the last stop of Wang's four-nation tour of Asia. His discussions with the South Korean hosts involved such issues as the 2022 Beijing Winter Olympics and the denuclearization of the Korean Peninsula.
