Addressing the event, Vietnamese Ambassador Vu Hong Nam reviewed Vietnam's achievements over the past 77 years.
From one of the least developed countries in the world, Vietnam has become a middle-income developing country and is recognised by the United Nations as one of the leading countries in the implementation of the Millennium Development Goals (MDGs), he said.
Vietnam has established diplomatic relations with 190 countries around the world and has economic partnerships with more than 230 countries and territories. It is a member of 15 free trade agreements (FTAs) and is also an active member of more than 70 multilateral organisations and forums, he added.
Regarding the ties with Japan, the Ambassador said the two countries will celebrate the 50th anniversary of their diplomatic ties in 2023, and expressed his belief that the Vietnam-Japan relations will continue to develop strongly and substantively in the coming time.
The National Day of Vietnam was also observed at a ceremony held by the Vietnamese Embassy in Pretoria, South Africa, on the same day.
