In 1899, the united states divided control of the samoa islands with

Germany

The islands were divided to settle international disputes over land.

The Samoan Islands had European visitors starting in the 17th century with the Dutch, British, Germans, and the US in the 1870s after creating a treaty for naval space. In 1899, there was a dispute in Samoa over leadership in which Germans and the US got involved. It ended with the dividing of the islands in 1899 with the eastern islands going to the US and the western islands going under the control of the US.
