S. Korean President Yoon meets with Biden to discuss nuclear protection.

South Korean President Yoon Suk Yeol will visit the White House this week to commemorate the 70th anniversary of the mutual defense treaty between South Korea and the United States. The alliance has become increasingly important as China challenges the US's global primacy. Yoon is expected to come under pressure to join other democracies in supplying artillery shells to Ukraine, which is running critically low on ammunition. Other frictions remain in US-South Korea relations, such as the repercussions of the Inflation Reduction Act and the Chips Act for South Korean manufacturers, as well as a growing desire among South Koreans for their country to acquire its own nuclear weapons despite the US security guarantee.
