Presidents Joe Biden and Yoon Suk Yeol will sign an agreement that includes plans to have US nuclear-armed submarines dock in South Korea for the first time in more than 40 years, according to senior Biden administration officials.

The planned dock visits are a key element of what is being dubbed the Washington Declaration, aimed at deterring North Korea from carrying out an attack on its neighbour.
