The award, considered as the highest honour conferred by the government on foreign nationals of Indian origin, was presented to Nathan by Overseas Indian Affairs Minister Vayalar Ravi at a function in Singapore yesterday.
The function was attended by officials of Singapore Government, a large number of prominent Indian nationals and Indian origin people in Singapore.
The Pravasi Bhartiya Samman is generally presented at Pravasi Bhartiya Divas -- the annual event organised to connect with the diaspora community.
Nathan could not travel to Jaipur where the event was organised in January this year.
