Vietnamese carriers are flying to Bangkok, Doha, Dubai, Frankfurt, Hong Kong, Istanbul, Kuala Lumpur, London, Moscow, Paris, Phnom Penh, San Francisco, Seoul, Singapore, Sydney, Taipei, Tokyo, and Vientiane, the Civil Aviation Authority of Vietnam said in a report.
China only allows outbound flights as it still pursues a zero-Covid policy with stringent entry restrictions.
Vietnam allowed a gradual resumption of aviation services on January 1 after over two years of suspension.
Some 153,000 people have so far flown into or out of the country.
On Tuesday the country ended all restrictions on international flights.
