Clarify the role played by non- …

The Non-aligned Movement aimed at establishing a new and equitable international economic, social and political order. The Non aligned Movement(NAM) gave the newly independent countries a way of staying out of the alliances. Countries outside the two blocs, for example, the non-aligned countries played a role in reducing Cold War conflicts and averting some serious crises. Jawaharlal Nehru, one of the key leaders of the NAM played an important role in mediating between the two Koreas, thereby resolving the arousal of conflicts.
Furthermore, India adopted the policy of NAM. As a leader of NAM, India's response to the ongoing Cold War was of two fold:

Firstly, it took particular care in staying away from the two alliances and it acted as a mediator between two rival alliances. India did so for the cause of peace, security and stability. Secondly, it raised its voice against the newly decolonised countries becoming part of these alliances.
Some examples where India exercises the policy of NAM by taking an independent decision are as follows :

i. India led the world protest against Britain, when the Britain attacked Egypt over Suez Canal issue in 1956 and

ii. The bold decision of India refusing to sign the NPT (Nuclear Non-Proliferation Treaty) in 1968.

India always tried to activate regional and international organisations, which were not a part of any alliances. India also help in taking measures for the economic development of third world countries, non-aligned, newly decolonised countries to enable them to pursue independent policies.
Thus, India played an active role in keeping the Non-aligned Movement alive and relevant.
