Thirty years ago on September 17, 1991, the two Koreas formally joined the United Nations.
In 1953 when the Korean War ended in a ceasefire, South Korea was one of the poorest nations in the world.
Since then, it has seen significant progress in democracy and become one of the world's largest economies.
In 2009, South Korea joined the OECD Development Assistance Committee, formally transforming from a recipient to a donor country.
This year, the country was categorized as a 'developed country' by the UN Conference on Trade and Development.
On the global stage, a number of South Koreans have made major contributions to the United Nations, taking the chairs of the UN General Assembly, Human Rights Council, and Economic and Social Council among others.
South Korean diplomat Ban Ki-moon also served as the Secretary-General from 2007 until 2016.
South Korea has twice served on the UN Security Council as a non-permanent member, first from 1996 to 1997 and again from 2013 to 2014.
The country is making another bid for a non-permanent member seat for the 2024-to-2025 term.
This year, President Moon Jae-in is attending the 76th UN General Assembly in New York, making his appearance at the Assembly for five consecutive years during his term of office.
Seoul's foreign ministry officials say this shows South Korea values multilateralism and the UN diplomacy, particularly as it marks three decades of UN membership.
