Portland has an established sister-city program.
## Sister cities - **Ashkelon, Israel** - **Bologna, Italy** - **Guadalajara, Mexico** - **Kaohsiung, Taiwan** - **Mutare, Zimbabwe** - **Nantes, France** - **Sapporo, Japan** - **Suzhou, China**
Sister-city relationships can evolve over time, so the City of Portland or affiliated sister-city organizations are the best source for the current official list.
