The article argues that the contours of a security architecture are becoming slowly visible in South Asia. This process is nurtured by two developments. First, since the 2000s, India has increased its security cooperation with nearly all its neighbours in South Asia. Second, since 2013 governments in New Delhi have promoted the concept of India as a security provider in the region and the Indian Ocean. The process towards closer security cooperation also indicates that threat perceptions among most South Asian countries vis-à-vis non-state actors have converged, so that security today is sought by cooperation rather than by confrontation.
