What makes this book unique is the way in which it combines the past, present, and future of three very different countries - India, Burma, and China - weaving together the history and politics of each place in a way that provides fresh insights into all three.
Only the first part is actually about Burma, the politics there today, the history of this incredibly diverse country, with mountain peoples even today at war with the central government, and the ways in which it is finding itself now increasingly squeezed between Asia's two big powers. He takes the reader from Rangoon up to the border regions where China is launching huge infrastructure projects but where Chinese people are also settling in huge numbers and where Chinese culture and language are starting to make big inroads.
It's the second part that really unveils the central premise: that something very special is happening now, with a Chinese frontier that has moved steadily south-westward for more than two thousand years, finally reaching Burma's Irrawaddy valley and the edge of Indian civilization. It's a fascinating idea that I have not heard anywhere else, despite all the hundreds of books on China's 'rise' to global power. As the author explains, through wonderfully told historical stories, what is today southwestern China was once, a myriad of small kingdoms and even (non-Chinese) empires - a view that would be entirely unacceptable to today's Chinese leadership. Only slowly, over centuries, did the Chinese gain control - making war, making treaties with local chiefs, sending in settlers, crushing rebellions, in a way strikingly similar to the European colonization of other parts of the world. It was a process, the author says, that has continued well into the 20th century. The 'China' part of the book, which is about a third of the whole, is a travelogue, partly to Beijing (to discuss current geopolitics) but partly through this realm of forgotten and conquered kingdoms.
Then there's India, and is this part (another third), the author travels from Delhi and Calcutta to the Northeastern provinces, barely known to outsiders, and explores the legacies of the British partition of the country, and the creation of what became Bangladesh. He also takes us on a tour of a whole other set of forgotten kingdoms, now part of the India, and the literally hundreds of different peoples in that part of the country, peoples once linked to Burma and to the southwest of today's China. He also discusses ancient ties that once bound India to Burma and beyond, through religion, culture etc. At the heart of this part is an exploration of the question of why, in these new borderlands, its China and not India that seems to be the more dynamic player.
If all this sounds confusing, it's not when you read the book. The travelogue is engaging, and will take you on trips you're very unlikely to ever go yourself. The history is extremely entertaining, with unexpected characters (like Herbert Hoover making a cameo) and stories ranging from those of ancient explorers to the 1962 Sino-Indian War and beyond. And the author's discussions of current and future politics will make you see the map of Asia in a very different way.
