The U.S. and South Korea are preparing to announce steps on Wednesday to strengthen their alliance and deter North Korea, as South Korean President Yoon Suk Yeol made a state visit to Washington.
A U.S. official, speaking on anonymity, said Washington will deploy a U.S. ballistic missile submarine to the western Pacific for the first time since the 1980s, to be followed by other U.S. military hardware.
The official added that the two nations will establish a consultative group to discuss deterring North Korea from using its nuclear weapons, a group like what the U.S. had with European allies during the Cold War. Those measures will be outlined in a "Washington Declaration," set to be issued by the two leaders later in the day.
South Korea has been requesting and the U.S. has been promising to give Seoul a bigger say in how to deter North Korea, including more joint planning, consultation and intelligence sharing.
