Guide to establishing
sister city relationships
A sister or friendship city relationship is formally created when the mayors or highest elected or appointed officials from
two communities sign a memorandum of understanding establishing the partnership. However, this is usually the result
of a long process that involves the local sister city organization along with the municipality and other local institutions.
While process can also be very different for each community and can vary from culture to culture, this guide can serve
as a point of reference in guiding communities through the process.
THE STEPS
PLANNING PROCESS The first step in developing a new sister city relationship is to ensure everyone is on the
same page. This would include the local sister city organization and the highest elected/ranking official, provided
this individual approves and formalizes the partnership. The contact information for local sister city
organizations may be found by using the “City Search” tool on the Sister Cities International website at
http://www.sistercities.org/.
RESEARCH PHASE Sister City relationships are strategic long term partnerships that should be mutually
beneficial, and identifying potential partners is the foundation to developing a successful relationship. If you
don’t already have a potential sister city in mind, below is a list of data points that communities should look for
similarities when identifying potential partners.
- Population size Some variance in city sizes is natural, but choosing a sister city of a similar size usually
ensures good symmetry between municipal governments, community groups, private organizations, as
well as similar challenges/opportunities
- Geography Similar geographic qualities, whether it’s ports, deserts, lakes, mountains, climate, etc.
often means that cities will be able to share valuable knowledge related to the respective challenge or
opportunity associated with each quality
- Industries
- Academic institutions High school and university exchanges, which are often a part of any relationship,
require similar counterpart institutions that should be identified early in the process
- Cultural institutions This may include museums, music venues, community centers
- Preexisting Relationships This may include, but is not limited to: mayoral relationships, trade
relationships, expatriate/diaspora communities, faith-based groups, and personal experiences ranging
from study/work abroad to marriages
- Historical or ancestral connections
Many communities have developed criteria or policies to guide their research or to evaluate inbound inquires,
whether from cities abroad or local residents, in order to manage the volume of requests as well as ensure that
potential relationships are both appropriate and sustainable. If you are interested in developing such a policy
please email membership@sistercities.org for more assistance as part of our Governance and Policy Services.

Sister Cities International works with U.S. and
global members on establishing new partnerships
through the Cities Seeking Cities program. This
program provides members with hand-in-hand
assistance in researching potential partners,
developing a line of communication through
various channels, consulting in international
protocol matters, and ultimately serving as a
resources for any questions throughout the
correspondence. For more information on the
Cities Seeking Cities program please visit our
website at http://sistercities.org/cities-seeking-
cities.
DEVELOP LINE OF COMMUNICATION The next
step in the process is to develop a line of communication
with the prospective community by sending a letter of
introduction from one mayor to the other. This letter
should introduce your community, identify why you are
interested in developing a sister city relationship, identify
potential program/exchange opportunities, and identify
a point of contact for this initiative. This is when
international protocol should be followed in order to
ensure a positive experience. Provided symmetry is a key
aspect of international protocol, if your local sister cities
organization operates through the work of community
volunteers it is good practice to identify a volunteer
contact as well as a contact within the mayor’s office. If
you need assistance in targeting appropriate contacts within the international community, please contact
partnerships@sistercities.org for staff assistance through our Cities Seeking Cities program. A template for this
letter may be found under the toolkits and templates section of the SCI Member Area
http://www.sistercities.org/toolkits-templates.
CORRESPONDENCE PHASE Once the letter has been received by the international community and a line of
communication has been established, the next several months should be focused on learning more about the
each other’s communities, identifying program/exchange opportunities, discussing local involvement, and
developing a work plan that establishes short and long term goals for the partnership. Many cultures will
recommend a physical exchange during this phase, but often various means of technology is used to effectively
communicate. This period is also a great opportunity to implement a program to “test the waters.” This program
could include a youth pen pal exchange, municipal/professional best practice, or other knowledge-sharing
exchange, among many other opportunities. Many communities may send non-mayoral delegations during the
correspondence and planning stages-whether that be the city manager, council members, local business
professionals, or volunteers.
DEVELOP PARTNERSHIP AGREEMENT Both communities have decided to move forward and formalize the
relationship. In order for a sister city, county, or state partnership to be recognized by Sister Cities International,
the two communities must sign formal documents which clearly endorse the link. The partnership agreement
can range from the ceremonial, with language focusing on each city’s commitment to fostering understanding,
cooperation, and mutual benefit to the precise, with particular areas of interest, specific programs/activities, or
more concrete goals related to anything from numbers of exchanges to economic development. Sister Cities
International has developed a toolkit and template that will assist in creating this document and can be found
under the toolkits and templates section of the SCI Member Area here: http://www.sistercities.org/toolkits-
templates.
SIGNING CEREMONY Once the partnership agreement has been developed and both communities have
approved the document, the two highest ranking officials will sign the document, which is often done during a
formal signing ceremony. While it is important to tailor these ceremonies to fit your specific communities, Sister
Cities International has developed a guide to this process and can be found under the under the toolkits and
templates section of the SCI Member Area here: http://www.sistercities.org/toolkits-templates. Once the

agreement has been signed, please send an electronic copy of that agreement to Sister Cities International at
membership@sistercities.org. The partnership will then be added to your communities profile on SCI website
and a certificate will be issued recognizing the partnership.
IMPLEMENTATION AND EVALUATION Sign, sealed, delivered. It is time to implement programs and plan
exchanges outlined in the work plan developed during the early months of this process. It is good practice to set
a date, whether within the next six months to two years, to evaluate the partnership and make adjustments if
needed. If you ever come across any issues, concerns, or are looking for program ideas, please do not hesitate to
contact Sister Cities International.
