In middle- and high-school, Delong worked hard, enjoyed studying and got good grades. When he turned 16, despite his young age, one of his teachers felt he was ready for college—but his protective grandparents preferred to have him wait another year. He took the entrance exam and passed it, and a few years later at age 21 Delong obtained his Bachelor degree in mechanical engineering and was offered a job by the government. "We had few job options at the time; I chose science and technology and began working for a library affiliated with the Ministry of Science and Technology. My job consisted of writing abstracts in Chinese and English for books destined to students and the public, a great opportunity to acquire culture and knowledge in all kinds of different fields."
Luo Delong—an expert in intergovernmental cooperation and science and technology diplomacy—has ties to the ITER Project that are deep and longstanding, dating all the way back to the negotiations that led China to join as an ITER Member. He took up the position of ITER Organization Deputy Director-General for Corporate on 1 April 2023.
