China and the United States appear headed for a damaging confrontation over the extent of China's territorial claims in the South and East China Seas.

Now that China has become the world's largest importer of oil, and energy more generally, the country's need to develop more indigenous energy supplies has become urgent.

Expecting China to put the South and East China Seas off limits to exploration and production until disputes over sovereignty can be resolved through some undefined legal or diplomatic process is unrealistic.
