Michael Dillon's study is not as lengthy as the similar study by Jonathan Fenby, but it has it's own strengths, and can be recommended to those, like myself, who already have similar volumes of Chinese history or politics behind them.
Dillon's study is essentially a sweep of history from the early to mid 19th Century up to the present.
An advantage of Dillon's work is a greater insight into the unequal treaties and century of humiliation heaped upon China, and the subsequent 1911 revolution, warlord era, and invasion by Japan.
Where the book is relatively brief, or at least not as detailed on other works, is the post 1949 era, which is not as detailed as Fenby's work, and there is much less study of the post Deng era, with leaders such as Hu Jintao and Wen Jiabao getting only a brief mention, and the events of 1989 figure very little within this book.
However, a strength of China: A Modern History is the chapter on Tibet and Xinjiang. This gives far more detail on the unease and tensions in these turbulent regions than other works have done, and one can gain a sense of sympathy for the Uyghurs and Tibetans and appreciate why there are underlying tensions.
In all, a recommended book. While some may have read other studies of modern Chinese history, this one is a welcome addition to their study if they want to go further, or a less time consuming read than Fenby's longer, though superior study.
But on the whole recommended, to old and new China hands alike.
