Hanoi. Nguyen Phu Trong, general secretary of Vietnam's ruling Communist Party and the country's most powerful politician, has died following months of ill health, official media said Friday. He was 80.

"General Secretary of the Central Committee of the Party Nguyen Phu Trong passed away at 13:38 on July 19, at the 108 Central Military Hospital due to old age and serious illness," the Nhan Dan newspaper said.

Official media said a state funeral would be held.

Trong had dominated Vietnamese politics since 2011, when he was elected party chief. During his tenure, he worked to consolidate the Communist Party's power in Vietnam's single-party political system. In the decade before he took the top role in Vietnamese politics, the balance of power had shifted more toward the governmental wing led by then-Prime Minister Nguyen Tan Dung.

Born in 1944 in Hanoi, Trong was a Marxist-Leninist ideologue who earned a degree in philosophy before becoming a member of the Communist Party at the age of 22. He viewed corruption as the single gravest threat in maintaining the party's legitimacy.

"A country without discipline would be chaotic and unstable," Trong said in 2016 after being reelected to the party's helm. Officially, Vietnam has no top leader, but the Communist Party chief is traditionally seen as the most powerful.

He launched a sweeping anti-corruption campaign known as the "blazing furnace" that singed both business and political elites. Since 2016, thousands of party officials have been disciplined. They included former presidents Nguyen Xuan Phuc and Vo Van Thuong and the former head of parliament, Vuong Dinh Hue. In all, eight members of the powerful Politburo were ousted on corruption allegations, compared to none between 1986 and 2016.

Trong studied in the Soviet Union from 1981 to 1983, and there was speculation that under his leadership, Vietnam would move closer to Russia and China. However, the Southeast Asian nation followed a pragmatic policy of "bamboo diplomacy," a phrase he coined that referred to the plant's flexibility, bending but not breaking in the shifting headwinds of geopolitics.

Vietnam maintained its traditional ties with its much larger neighbor, China, and disputes differences over sovereignty in the South China Sea. But it also drew closer to the United States, elevating its ties with its former Vietnam War foe to its highest diplomatic status, a comprehensive strategic partnership.
