A North Korean drone briefly entered a no-fly zone surrounding South Korea's presidential office when it intruded into the South's airspace last week, Seoul's military said on Thursday, fuelling criticism over its air defences.
A senior U.S. administration official elaborated, adding that both sides are looking at enhanced information-sharing, joint contingency planning and an eventual tabletop exercise following a request from their presidents after a meeting in Cambodia in November to explore ways to address North Korea's threats. But the official noted regular nuclear exercises would be "extremely difficult" because South Korea is not a nuclear power, echoing the comment from U.S. President Joe Biden late on Monday that the allies were not discussing such activities.
"In order to respond to the North Korean nuclear weapons, the two countries are discussing ways to share information on the operation of U.S.-owned nuclear assets, and joint planning and execution of them accordingly," Yoon's press secretary, Kim Eun-hye, said in a statement.
