SEOUL - The United States and South Korea agreed on Saturday to step up measures to deter North Korea, and expand cooperation on a range of measures from cybersecurity and nuclear energy to regional security and supply chains.

In a joint statement issued after the first summit between U.S. President Joe Biden and new South Korean President Yoon Suk-yeol, the two countries vowed to expand their alliance to tackle issues beyond North Korea, while remaining open to talks with Pyongyang.
