A 1968 graduate of Seoul National University, Chung joined the Ministry of Foreign Affairs in 1971. He subsequently served as Korean Ambassador to Israel (1997–1998), Deputy Minister for Trade (1998–2001), and as Korean Ambassador to the Permanent Mission of the Republic of Korea to the UN Secretariat and International Organizations in Geneva (2001–2004). He was returned to the 17th National Assembly in the 2004 elections as a proportional representative for the Uri Party. In the National Assembly, he was a member of the Special Committee on United States–Korea Free Trade Agreement. He then became Secretary-General of the International Conference of Asian Political Parties. On 20 May 2017, newly-inaugurated president Moon Jae-in appointed him as the ministerial-level Director of the National Security Office. In July 2020, Chung was replaced by Suh Hoon and reshuffled to President Moon's Special Advisor on Foreign Affairs, Diplomacy and National Security. In January 2021, he replaced Kang Kyung-hwa as the new South Korean Foreign Minister.
In March 2018, as South Korea's Special Envoy to North Korea, Chung Eui-yong visited Pyongyang to discuss the required steps to denuclearise North Korea. He then flew to the United States for a meeting with President Donald Trump and to announce the Trump-Kim summit.
