Pacts of May

- Acta Preliminar: Argentina renounces the ability to intervene in the Chilean affairs in the Pacific Ocean 2.

- Convención sobre Limitación de Armamentos Navales: The most famous of the protocols is the arms control treaty.

As a consequence of territorial disputes both countries had begun to increase their military budgets and an arms race ensued in the 1890s.

Of longer-lasting importance, the pact resolved the power projection competition by assigning each country a sphere of influence: Chile in the Pacific and Argentina in the Atlantic and Rio de la Plata.

Chile denied the argument, saying that the pacts are not a border treaty and therefore no place is named as limit between the Pacific and the Atlantic.
