Bolivia has taken Chile to the International Court of Justice in The Hague in respect of its demand to be allowed a sovereign outlet to the sea for its products. Chile, for its part, stresses that Bolivia already has relatively open access to its ports.

In 2014, for example, 7,000 Bolivian companies made use of the Chilean ports of Arica, Iquique, Mejillones and Antofagasta to move their cargo, in accordance with the 1904 treaty signed between the two countries. In 2014, this cargo amounted to 3.5 million tonnes, up 3.4% on 2013, with Arica accounting for 71% of total cargo.
