President Yoon Suk-yeol is making his multilateral summit debut in Spain.
Slated for Wednesday afternoon, local time, are the North Atlantic Council meeting with the Asia-Pacific partners, a trilateral summit between South Korea, the U.S., and Japan, and a four-way meeting of the Asia-Pacific countries.
At the NATO summit, the South Korean President will make a speech looking to shore up international support for North Korea's denuclearization.
And for the first time in almost five years, there will be a trilateral between the leaders from Seoul, Washington and Tokyo, who are likely to focus on regional security involving North Korea's nuclear and missile programs.
In fact, earlier on Tuesday, President Yoon and the Australian Prime Minister agreed to strengthen cooperation against the North's nuclear programs, during which the Australian side pledged to continue strict implementation of sanctions on the regime.
Also agreed were cooperation on green energy, high-tech materials and minerals.
"With the launch of new governments in both countries, I hope for close cooperation to further develop our relations."
And at a gala on Tuesday, Japan's Prime Minister Fumio Kishida said hello to President Yoon and congratulated him on his inauguration and local election results in South Korea.
In response, President Yoon reportedly expressed his wish for positive election results for Prime Minister Kishida in the upcoming House of Councillors elections in Japan, after which, he said he hoped for talks with Tokyo to resolve pending issues for a "future-oriented" relationship.
A four-way meeting involving South Korea, Japan, Australia and New Zealand is also scheduled for Wednesday.
It remains to be seen whether there will be talks on regional security, amid the Russian invasion of Ukraine and China's increasing assertiveness.
