France was chosen to host the world's first nuclear-fusion reactor, ending a deadlock with Japan over a location of the 4.6 billion euro ($5.6 billion) experiment involving the European Union, Japan, the U.S., Russia, China and South Korea.

The six members of the International Thermonuclear Experimental Reactor, or ITER, which means ``the way'' in Latin, agreed in Moscow today to build the facility in the southern French city of Cadarache, rather than Rokkasho-Mura, the Japanese location favored by the U.S. and South Korea.
