Seoul: Today in Korean history marks significant milestones in South Korea's international relations and political landscape. In 1991, President Roh Tae-woo made a pivotal declaration that South Korea will not pursue nuclear armament, setting a tone of peace and diplomacy in the region. This decision was a crucial step in promoting stability on the Korean Peninsula and showcasing South Korea's commitment to global non-proliferation efforts.

According to Yonhap News Agency, 1995 was another landmark year for South Korea as it was elected a non-permanent member of the U.N. Security Council. This election underscored South Korea's growing influence and responsibility on the global stage, allowing it to play a more significant role in international peace and security matters.

In 2011, President Lee Myung-bak held a summit in Seoul with Vietnamese President Truong Tan Sang. The discussions focused on enhancing cooperation in nuclear power plant construction, reflecting South Korea's technological advancements and its interest in fostering strong bilateral ties with Vietnam.
