Developing municipal partnership between towns, cities, counties, states. This is to create opportunities for the citizens of member cities to experience and explore other cultures through long-term municipal partnerships; create an atmosphere in which economic development and trade can be developed, implemented and strengthened; stimulate environments through which municipal partnerships can creatively learn, work and solve problems together.
