There has been significant overlap between paramount leader status and leadership core status, with a majority but not all of paramount leaders being also leadership cores, though they are separate concepts. The term has been used less frequently to describe Deng's successors, Jiang Zemin, Hu Jintao and Xi Jinping, who have all formally held the offices of General Secretary of the Chinese Communist Party (Party leader), President of the People's Republic of China and Chairman of the Central Military Commission. Jiang, Hu and Xi are therefore usually referred to as president in the international scene, the title used by most other republican heads of state.
