The Sikyong was visiting the Scandinavian nation to participate in the Oslo Freedom Forum, where his talk, 'Democracy in Exile' was part of a session titled, 'The Asymmetric Activist'.
Other participants in the session included renowned Chinese human rights activist Chen Guangcheng, who escaped house arrest and fled China in 2012 and Bill Browder, the American businessman who gained fame for his activism to expose corruption and human rights abuses in Russia.
In his speech, the Sikyong said that Tibet is a "litmus test for the international community and China".
The Sikyong also visited the Nobel Institute, where he was received by Mr Geir Lundestag, the Secretary General of the Norwegian Nobel Committee. The Sikyong thanked the Nobel committee for their support for the Tibet cause over the years.
The Norwegian Nobel Committee had awarded His Holiness the Dalai Lama, the Nobel Prize for Peace in 1989, for his peaceful " struggle for the liberation of Tibet, consistently opposing the use of violence" and instead advocating " peaceful solutions based upon tolerance and mutual respect'.
Dr Sangay later addressed more than 70 members of the Norwegian Tibet Committee and also gave interviews to prominent International and Norwegian media corporations and publications including the BBC Radio Service, Aften Posten, Newsweek and The Atlantic.
