Does Vietnam's economic future still look bright?

Vietnam has enjoyed more than 6% annual growth every year for the last thirty years or more, a staggering growth path, transforming one of Asia’s poorest economies into a major global trading hub. It's now one of the world’s top twenty economies. But are there challenges ahead. A high-profile anti-corruption drive, extreme weather events, and the death of its long-term leader have raised questions about the country’s path to prosperity.(Picture: Aerial view of Ho Chi Minh City, Vietnam, at night, showing high-rise buildings, the Landmark 81 supertall skyscraper, and transport networks.
