All 495 lawmakers present endorsed his nomination, according to parliament, formalizing a dual leadership structure that departs from Vietnam’s long-standing system of collective governance.

Lam, who secured a second term earlier this year as head of the Communist Party of Vietnam, now holds both the top party and state positions for the next five years. Analysts say the concentration of authority could streamline policymaking but also raises concerns about increased centralization of power.

In a televised address after the vote, Lam pledged to pursue a new growth strategy driven by science, technology, innovation and digital transformation, while emphasizing stability, self-reliance in defense and improvements in living standards.

The leadership shift marks a structural change in Vietnam’s political system, bringing it closer to models seen in other one-party states where power is concentrated in a single figure.

Observers say this could accelerate economic decision-making in the fast-growing Southeast Asian economy.Lam, 68, previously served as minister of public security and has promoted reforms aimed at boosting competitiveness and reducing reliance on low-cost manufacturing.

His policies have drawn both praise from investors and concerns over potential risks such as market distortions, favouritism and asset bubbles.Vietnam’s foreign policy is expected to remain broadly unchanged, with Lam continuing a balancing approach between major powers while expanding global partnerships.

The National Assembly is expected to appoint a new prime minister later on Tuesday to replace Pham Minh Chinh.
