This book focuses on new approaches to understanding the changing context of foreign policy decision-making in the country, historically and for the future. The traditional mode of the domestic, external, and personality traits of the respective prime ministers and their governments over the years, and the nature of their responses to keep up with the changes and to maintain continuity with the past, all have a big influence on their decisions. In the four case studies presented, the factors of political continuity managed by the leadership and those that emphasize history, decision-making, key issues, and big-picture and paradigmatic analysis, are considered together with the DIY foreign policy of Prime Minister Najib Razak, and the change in continuity foreign policy framework of Prime Minister Tun Dr. Mahathir Mohamad and the short-lived Pakatan Harapan government. The book closes with a look at the future of diplomacy in the world and the region amid the COVID-19 pandemic and the political uncertainties in the present government in the country.
