South Korean Unification Minister Lee In-young listens to a question during a press conference at the Seoul Foreign Correspondents' Club in Seoul, South Korea, February 3, 2021. - Reuters SEOUL (The Straits Times/ANN): South Korea's point man on inter-Korean affairs has pledged to mount "diverse efforts" to restart stalled nuclear talks and work with the new Biden administration to bring Pyongyang back to the negotiating table. Imposing more sanctions may not work, said South Korea's Unification Minister Lee In-young. Earlier this week, United States Secretary of State Antony Blinken said that the new Biden administration could resort to additional sanctions in cooperation with US allies to push North Korea towards abandoning nuclear weapons.
