Pakistan’s relations with China have always been the most important of its relationships with other countries. It is based on trust, respect, and mutual benefit. Over the past 55 years, since the two countries established their diplomatic relations, this relationship has evolved in a manner to serve the interests of both countries. To understand the evolution of this relationship from a correct perspective, it is important to have a brief overview of the relationship between the two countries. China’s adversarial relationship with India has been one of the important factors in its all-weather friendship with Pakistan. Such an intimate relationship between the two had developed at a time when China’s global profile had not developed to the extent that is discernable now. Over the years, Sino-Indian relationship has also matured to a greater degree of engagement. China is now projecting itself as a responsible global power, beyond the sub-continent and the region. One can fathom China’s primordial commitment to Pakistan and China’s imperative need for Pakistan’s support to rein in Muslim separatists operating in China-Pakistan border in the Uygur region, but China needs to calibrate its relationship with Pakistan in the context of these changes and in such a manner so as not to arouse any misgivings in New Delhi. As the book addresses this crucial issue quite deftly, it is hoped that it would prove to be a source of great information for the reader.
