"The United States congratulates the people of Bhutan on their successful July 13 general election, and welcomes Bhutan's continued democratic progress following its first national elections in 2008," said Jen Psaki, State Department spokesperson.
"The United States looks forward to working with the new Bhutanese Prime Minister and National Assembly on our shared goals and aspirations for both our peoples," said Psaki.
Bhutan's main opposition People's Democratic Party (PDP) won 32 of the 47 national assembly in the elections held last week.
It was in 2008 the Bhutanese king gave up absolute power of his monarchy and introduced democracy in the country.
