A U.S. official announced that today, Wednesday, U.S. President Joe Biden and South Korean President Yoon Suk-yeol are expected to agree on strengthening cooperation aimed at deterring North Korea's nuclear escalation amid growing concerns over its expanding arsenal of missiles and munitions. The allies will take advantage of the first official visit of a South Korean president to Washington in over a decade to send a warning to North Korean leader Kim Jong-un.
The two presidents are expected to agree on a new "Washington Declaration," which U.S. officials describe as providing South Korea with a detailed insight and voice regarding the United States' planning to deter any nuclear incident in the region through the U.S.-South Korea Nuclear Consultative Group. Senior U.S. officials stated via phone that "while the allies will affirm that diplomacy with North Korea is the best solution, Washington will announce that it will deploy mandated military technology, including a submarine capable of launching ballistic missiles to South Korea as a show of force." They added that this will be the first visit of such a submarine since the 1980s.
