PRAGUE, Nov. 28 (Yonhap) -- South Korean President Moon Jae-in and U.S. President Donald Trump will discuss joints efforts to peacefully denuclearize North Korea, an official from Seoul's presidential office Cheong Wa Dae said Wednesday, confirming the leaders will meet on the sidelines of the upcoming Group of 20 summit in Argentina.
"South Korea and the U.S. have agreed to hold a summit between President Moon and President Trump during the G-20 summit to be held in Buenos Aires," Moon's chief press secretary Yoon Young-chan told a press briefing.
"At the upcoming summit, the leaders of South Korea and the U.S. plan to focus on ways to increase cooperation in the process of complete denuclearization of the Korean Peninsula and establishment of permanent peace, as well as ways to strengthen the South Korea-U.S. alliance," the Cheong Wa Dae official added.
The exact schedule and venue of the Moon-Trump summit have yet to be decided.
Moon arrived here Tuesday on his way to Argentina. He is set to head for Argentina later in the day. The annual G-20 summit will be held for two days from Friday.
Moon and Trump last met on the sidelines of the United Nations General Assembly in New York in September, shortly after Moon's historic trip to Pyongyang earlier that month for his third inter-Korean summit with North Korean leader Kim Jong-un.
This week's meeting comes amid an apparent stall in North Korea's denuclearization progress, reflected in a similar stall in denuclearization negotiations between the United States and the North.
Trump has agreed to hold his second meeting with Kim, but not until the start of next year.
Such a delay in the second U.S.-North Korea summit may be impeding Moon's peace initiative, which earlier sought to declare a formal end to the 1950-53 Korean War before the year's end. The divided Koreas technically remain at war as the 1950-53 war ended only with an armistice.
Seoul officials have noted Kim's trip to Seoul may also be pushed back until after the second Trump-Kim summit, widely expected to be held in January.
The North Korean leader earlier promised to visit the South Korean capital before the year's end to hold his fourth summit with Moon.
