Bolivian President Evo Morales announced March 26 that his government will bring suit against Chile before the International Court of Justice seeking compensation for using the waters of the disputed Río Silala. Two days later, he made a visit to the river in Potosí department, where he declared, "Silala is not an international river." Chile's President Michelle Bachelet promptly responded that Bolivia has recognized the Silala as an international river for more than 100 years and said she would counter-sue before the World Court if Bolivia in fact brought a case. Originating in the high desert plateau of Bolivia's remote southeast, the Silala flows into Chile through a canal built for mining operations over a century ago. In 2009 Chile and Bolivia announced an accord to resolve the conflict, which would cut Chile's use of the Silala's water by 50%. But the pact was never formalized, and local communities in impoversihed Potosí demanded retroactive payment for Chile's past use of the waters.

Bolivia is already pressing a case against Chile at The Hague, seeking the right to a corridor to a "sovereign" corridor through Chilean territory to the Pacific Ocean. (AP, TeleSur, T13, Chile, La Tercera, Chile, March 28)
