India has made significant efforts for peace and unification of the Korean Peninsula. An Indian was appointed as the chairman of the UNTCOK and he opposed the division of the Korean Peninsula. When the Korean War broke out India sent a medical team and made efforts for the armistice agreement. Later India chaired the NNRC for the repatriation of POWs. During the Cold War period India's policy towards the Korean Peninsula was guided by non-alignment. After the end of the Cold War, India initiated economic liberalization and "Look East" policy which gave impetus to its renewed engagement with the Korean Peninsula. India has consistently urged North Korea to dismantle its nuclear and missile programs and has supported peaceful unification of the Korean Peninsula. India's deepening engagement with the two Koreas has been recognized by the US and it has been seeking India's help in diffusing tensions on the Korean Peninsula. This paper makes an analysis of the efforts made by India in the Korean Peninsula for peace and unification in a historical perspective.
