Oranjestad-Aruba Sister Cities Association is responsible for developing and fulfilling sister cities agreements on behalf of the City of Oranjestad-Aruba in the United States.

Even though the Aruba Sister Cities Program was created to stimulate people-to-people relationships, the association also acts as a liaison between elected government officials and dignitaries from the sister cities.

Strengthening municipal partnerships and advancing municipal cooperation are also stipulated in such unique agreements. 

OASCA assists in coordinating in-and outbound governmental visits and missions between the sister cities and ensures fraternal communication between the sister cities’ elected officials.
