HANOI—Vietnam’s President Tran Dai Quang, a former chief of internal security who became one of the most high-profile leaders in the communist-ruled country, died on Sept. 21, after an illness, state media said.
Quang’s rise, at a time of growing dissent on social media and challenges to the party’s authority, signaled limits to Vietnam’s liberal agenda, despite a growing openness to social change and sweeping economic reform, experts say.
