Accusations from the West that China is tearing up the Sino British Joint Declaration over Hong Kong are serious calumnies. This book shows how two diametrically opposed solutions were put together. The British wanted a treaty, and the Chinese wanted a unilateral declaration of policy. The policy was enshrined in treaty form – in other words -proving the maxim that a treaty between states is a disagreement put into writing. It is a riveting read, the work of a first class, razor sharp mind, a distinguished academic as well as a prominent barrister.
