SEOUL, Feb. 3 (Xinhua) -- South Korean President Moon Jae-in and U.S. President Donald Trump talked over phone about the Korean Peninsula issue and upcoming the Winter Olympics, the presidential Blue House said on Saturday.

Moon and Trump held a telephone conversation for 30 minutes on Friday night, agreeing to closely cooperate for the successful hosting of the Winter Olympics and Paralympic Games set to kick off on Feb. 9 in South Korea's eastern county of PyeongChang.

Moon expressed his gratitude to Trump for sending a high-ranking U.S. delegation, including Vice President Mike Pence, to the South Korea-hosted Winter Olympics.

The South Korean president said he hoped to make the PyeongChang Winter Olympics an opportunity for the inter-Korean dialogue that would last after the Winter Olympics and contribute to peace on the Korean Peninsula.

Moon wished that Vice President Pence's attendance at the Winter Olympics can become a significant turning point for that momentum.

During the high-level inter-Korean talks in January, the Democratic People's Republic of Korea (DPRK) agreed to send its athletes and cheerleaders to the South Korea-hosted winter sports event, as well as a high-ranking delegation.

During their phone talks in January, Moon and Trump saw a possibility for the inter-Korean talks naturally leading to a dialogue between the DPRK and the United States for the denuclearized Korean Peninsula.

The possibility cannot be ruled out for Pence to meet with ranking DPRK officials during the Winter Olympics.
