PHNOM PENH, Cambodia—President Joe Biden and the leaders of Japan and South Korea on Sunday vowed a unified, coordinated response to North Korea’s threatening nuclear and ballistic missile programs, with Biden declaring that the three-way partnership is “even more important than it’s ever been” when North Korea is stepping up its provocations.
Biden met separately with Japanese Prime Minister Fumio Kishida and South Korean President Yoon Suk Yeol before all three sat down together on the sidelines of the East Asia Summit in Cambodia.
