The Secretary of State to the Ambassador in Chile (Collier)
55. You are instructed, whenever a suitable occasion offers, to make it plain to Americans in Chile that this Government hopes they will abstain from all activities tending to favor one side in the Tacna-Arica controversy. Inasmuch as the President of the United States has been chosen as Arbiter, it behooves Americans resident in both Chile and Peru to maintain an absolutely neutral attitude toward this question and avoid all expressions of opinion which may tend to inflame partisan feeling and further strain the existing relations between the two countries.
You will also see that the sentiments of this Government as expressed above are fully understood by the Government of Chile.
Repeated mutatis mutandis to Lima.
