Head of the International Department On 30 September 2025, he was announced as the new
head of the International Department of the Chinese Communist Party, succeeding
Liu Jianchao who, according to sources, was detained by anti-corruption officials. In November 2025, Liu met with
Social Democratic Party of Germany co-leader
Lars Klingbeil as part of the party dialogue between the SPD and the CCP established in 1984. In January 2026, Liu wrote in the
People’s Daily that "frequent systemic crises within capitalism" and the success of the Chinese model means that "historical evolution and the competition between the two ideologies and social systems — socialism and capitalism — are undergoing a major shift on a global scale that increasingly favors socialism". He also argued that China's rise had shattered the "Western-centric" logic that equates modernization with Westernization and "sets a benchmark and provides a brand-new alternative for developing nations seeking to achieve modernization while maintaining their independence and autonomy". == Personal life ==
