a section of a law passed by Congress that detailed the borders of the new administrative region of Arica and Parinacota. The impasse was resolved by the Chilean Constitutional Tribunal, which declared that section unconstitutional. In March 2007, the Chilean state-owned and independent public broadcaster Televisión Nacional de Chile (TVN) canceled the broadcast of a documentary about the War of the Pacific after a cautionary call was made to the stations’ board of directors by Chilean Foreign Relations Minister Alejandro Foxley, apparently acting on demands made by the Peruvian ambassador to Chile; the show was finally broadcast in late May of that year.

The presidents of Bolivia, Ecuador, Uruguay, Argentina, Paraguay, Brazil and Colombia, and the Secretary-General of the Organization of American States, met with Bachelet at
