The idea of how India negotiates with the world is at the heart of this book. Career diplomat Mohan Kumar represented India at multiple international fora over a career spanning three and a half decades. During this time, he would invariably be told that Indian negotiators were among the best in the business. And yet, several of his interlocutors would ask, in the same breath, why India was such a tough customer when it came to multilateral negotiations. Indeed, it was hard to escape the view, held even by India's friends, that the country was somehow more of a naysayer than a partner in key international parleys. This book, then, is a sincere attempt to set the record straight. At one level, India is not very different from other countries insomuch as it seeks to protect where necessary, and advance where possible, its national interest. There are several unique aspects about India and the way it approaches multilateral negotiations with the world. This book dwells on some of those fundamental factors and traces how India's positions have evolved over time. A central contention of this book is that India has moved, slowly but surely, from being an alleged naysayer to becoming a putative partner for the world in key multilateral negotiations. More broadly, this reflects India's growing political, economic and strategic clout in the world today. It is only when this transformation is fuller and more substantial that India will be able to fulfil its manifest destiny of becoming a leading power, capable of shaping global rules.
