South Korean President Yoon Suk Yeol said on Tuesday that a planned nuclear consultative group and new partnerships on supply chains and science and technology are an "upgrade" to the country's alliance with the United States.
Yoon held a summit with U.S. President Joe Biden in Washington last week, during which they agreed to step up nuclear planning over North Korea by launching the consultative group, as anxiety grows in Seoul over Pyongyang's weapons programmes and the American nuclear umbrella.
