The member of Shivaji`s Astha Pradhana (Council of Eight Ministers) who looked after foreign affairs was the Sumant. The Sumant was responsible for handling diplomatic matters, foreign relations, and communication with other kingdoms and empires on behalf of Shivaji.

The Sumant played a crucial role in maintaining diplomatic relations, negotiating treaties, and managing the external affairs of the Maratha Empire under Shivaji`s reign. This position required strong diplomatic skills, knowledge of international politics, and the ability to represent the interests of the Maratha Empire in dealings with other powers.

It is important to note that the other positions in the Astha Pradhana were Peshwa (Prime Minister), Sachiv (Secretary), and Pandit Rao (Religious Advisor), each having their specific roles and responsibilities in the administration of the Maratha Empire.
