China has aroused international alarm by using its virtual monopoly of rare earths as a trade instrument and by stalling multilateral efforts to resolve disputes in the South China Sea. Among its neighbours, there is deep concern at the way it is seeking to make water a political weapon.
At the hub of Asia, China is the source of cross-border river flows to the largest number of countries in the world – from Russia to India, Kazakhstan to the Indochina peninsula. This results from its absorption of the ethnic minority homelands that make up 60 per cent of its land mass and are the origin of all the important international rivers flowing out of Chinese territory.
Getting this pre-eminent riparian power to accept water-sharing arrangements or other co-operative institutional mechanisms has proved unsuccessful so far in any basin. Instead, the construction of upstream dams on international rivers such as the Mekong, Brahmaputra or Amur shows China is increasingly bent on unilateral actions, impervious to the concerns of downstream nations.
