The book also briefly reviews the methodologies used and usefulness of the Social Protection Index (SPI) of the Asian Development Bank (ADB).Second, the book analyses strategies and specific initiatives used by the selected East Asian countries (China, India, Indonesia, the Philippines, Thailand, and Vietnam), designed to progress towards the social protection goals underlying the Social Development Goals (SDGs) adopted by the United Nations in September 2015, and endorsed by the countries covered in this book.Finally, the book provides a framework for generating fiscal space to fund the social protection programs and initiatives. The country chapters utilise this framework in the context of each specific country to suggest generating fiscal space.
