As the Rock Garden is an attraction within the Union Territory of Chandigarh, it shares the sister-city relationships established by the Chandigarh Administration.
* **Hangzhou, China:** Chandigarh signed a Memorandum of Understanding with Hangzhou to promote cultural, tourist, and economic exchanges, reflecting a shared focus on balancing urban development with natural landscapes. * _Note: The Rock Garden itself serves as an international ambassador of goodwill, with Nek Chand having been invited to create similar, smaller recycled gardens in cities around the world, though these are not official diplomatic sister-city ties._
