US-South Korea alliance strengthened amidst nuclear tensions with China and North Korea.

South Korean President Yoon Suk Yeol's visit to Washington, D.C. included a state dinner, a joint address to Congress, and the signing of the "Washington Declaration," which commits the two nations to a stronger mutual defense relationship. The declaration also calls for the complete denuclearization of the Korean Peninsula and could be seen as a message to China. Yoon's visit comes amid controversy over the revelation that the United States has been wiretapping his government. Additionally, South Korea's semiconductor industry, which produces 19% of the world's semiconductors, could be affected by the CHIPS Act, a $50 billion investment in the U.S. semiconductor industry that prohibits certain facilities in China.
