Building the First U.S. Sister City Partnerships with Papua New Guinea
A historic step in Pacific relationships took place when the United States established its first two sister-city partnerships with Papua New Guinea.
The City of Long Beach, California, partnered with Port Moresby, while the Village of Poplar, Wisconsin, partnered with Madang. Their exchanges are focused on students, culture, and shared World War II history. These local relationships complement the work of the U.S. Department of State and the U.S. Embassy in Port Moresby by creating additional ways for people to know and learn from one another.
Papua New Guinea rewards curiosity. The country is home to approximately 860 languages, more than any other nation. It is recognized for extraordinary biodiversity, scuba diving, and birdwatching, and it consistently lives up to its motto: “Expect the unexpected.”
That diversity also demonstrates why relationships cannot be built through assumptions. A country may appear as a single place on a map, but its communities carry distinct languages, histories, and perspectives. Effective citizen diplomacy begins by respecting that complexity and allowing local partners to define what meaningful exchange should look like.
Sister-city partnerships are powerful because they are designed for the long term. A signing ceremony is only the beginning. The real work comes through student exchanges, cultural programs, educational partnerships, and relationships among community members who continue showing up for one another.
These connections are created by regular people acting as citizen diplomats. Their efforts do not replace formal diplomacy. They strengthen it by adding trust, personal knowledge, and continuity.
The new partnerships with Papua New Guinea expand the map of U.S. people-to-people diplomacy. More importantly, they create opportunities for experiences that may change how participants understand another country, their own community, and what international friendship can accomplish.
