Basket I refers to the first category of the Helsinki Final Act, established in 1975 during the Conference on Security and Cooperation in Europe (CSCE). This basket primarily focuses on security and cooperation in Europe, emphasizing the principles of sovereign equality, refraining from the threat or use of force, and the inviolability of frontiers. It laid the groundwork for further discussions on human rights and cooperation among states, highlighting the importance of stability and peace in the region.
