hydro–politics A total of seven rivers that start in Tibet flow through India — Indus, Satlej, Karnali (Ghaghara), Subansiri, Brahmaputra and Lohit (and its tributary Dulai). Brahma Chellaney has written that "India's formal recognition of Chinese sovereignty over Tibet constitutes the single biggest security blunder with lasting consequences for Indian territorial and river-water interests". India has concern with China's water–diversion, dam–building and inter–river plans. Moreso, in a conflict, India fears that China can use the rivers as leverage. China has already constructed ten dams on the Bhramaputra and its tributaries such as the Zangmu Dam, and there has been talk of China building a mega–dam at the "great bend" called the Motuo Dam. India's concerns also stem from the fact that China does not cooperate with regard to timely sharing of information related to projects which would impact water sharing; nor does China allow Indian experts to visit dam sites. There are a number of MOUs on hydrological data sharing between the two countries with regard to the Brahmaputra including emergency management. An alternate view is also presented in relation to "misinformation spread by some (Indian) newspapers" and the waters of Brahmaputra — "80 per cent of the waters of the Brahmaputra emanate from the north side of the Himalayas in China and that that country cannot be the sole arbiter of its international waters. This is not right. Eighty per cent of the waters of the mighty Brahmaputra are picked up after it enters India" and that Chinese activities have helped India by reducing annual flood intensity in the north-east. Economic relations India-China economic relations have been institutionalized through the Joint Economic Group and Business Council, as well as more focused efforts such as the "Agreement on the Avoidance of Double Taxation". China and India have developed their own complementary skills following a period in which they had cut themselves off from each other. By 2007, while China excelled at cost-effective manufacturing, India was skilled in cost effective designing and development. In 2007 Tarun Khanna wrote in Harvard Business Review that "The simplest, and most powerful, way of combining China and India is to focus on hardware in China and on software in India." In the 2009 book "Getting China and India Right", the authors suggest a China plus India strategy so as to strategically benefit from both India's and China's scale, complementary strengths, and reducing the risk of
