South Korea and Vietnam to strengthen efforts against North Korea's nuclear threat.

South Korea and Vietnam have agreed to increase security cooperation to counter North Korea's nuclear threat and boost bilateral trade and investment despite a slump this year. The two nations signed 17 agreements on issues ranging from critical minerals to Vietnamese workers in Korea. They also agreed to boost defence industry relations and security cooperation in the South China Sea. South Korea is one of many countries discussing possible arms sales to Vietnam as it seeks to modernise its arsenal.
