Lhatu Wangchuk (born December 15, 1951 ) is the UN Ambassador from Bhutan, having assumed that office in January 2009.[1][2] He had served earlier as an ambassador to Bangladesh between 1998 and 2001, and was the tourism director general of Bhutan.[3] He is a member of the Wangchuck family.
In 2011, Wangchuk authored a UN resolution establishing "Gross National Happiness" as a human development indicator (HDI), alongside traditional measures such as Gross National Income. The motion was eventually backed by 66 co-sponsors and was brought into the UN agenda.[4]
