Lao or Laotian anthem lyrics (English translation)
For all time the Lao people
Have glorified their Fatherland,
United in heart,
Spirit and vigour as one.
Resolutely moving forwards,
Respecting and increasing the dignity of the Lao people
And proclaiming the right to be their own masters.
The Lao people of all origins are equal
And will no longer allow imperialists 
And traitors to harm them.
The entire people will safeguard the independence
And the freedom of the Lao nation.
They are resolved to struggle for victory
In order to lead the nation to prosperity.
