Nukes, Ukraine and semiconductors top Biden-Yoon agenda


South Korean President Yoon Suk Yeol’s visit to Washington this week is hitting on three incendiary issues: nukes, Ukraine and the technology tug-of-war with China.

Yoon and President Joe Biden are coming together to toast the 70th anniversary of the U.S.-South Korea mutual defense treaty which committed the two countries to assist each other in the event of “armed attack and communist subversive activities.”

But their meeting coincides with South Korea feeling particularly vulnerable to North Korea’s military threats and China’s increasingly expansive power projection in the Indo-Pacific — and wanting assurances that the U.S. is ready with support.
