The article aims to describe the regional security challenges and major threats for India in South Asia. Since 1947, India has been suffering from external security threats such as, a form of proxy warfare and terrorism from its neighbouring countries. To this purpose, the article also examines recurring issues where India has major border issues with China, in the Himalayan terrain to the eastern region of India. This article looks at the defence cooperation between India and France through the prism of India’s security threats in the South Asian region. India's soft power policy reflected in a neo-realist approach and expanded its long-standing defence cooperation with France. Therefore, India has been receiving support from the French government whenever the country needs defence equipment and other assistance. The article uses empirical and discourse analysis methods to answer the questions, and to draw a proper conclusion to the study. Finally, as a result of the study, we can see that India’s serious security threats in the South Asian region are pushing the country to purchase defence equipment from France. The relationship between India and France is strengthening the bilateral cooperation at a broader level and shaping a strong strategic partnership by uniting South Asia and the Indo-Pacific as well.
