Does Meishan belong to Nanjing or Shanghai now?

Shanghai. Meishan, located in the southwest suburb of Shanghai, is an enclave in Shanghai, bordering Nanjing and Wuxi in Jiangsu Province. Meishan was once a part of Jiangsu Province in history, but in 1958, the State Council approved Meishan to be assigned to Shanghai, which provided an important support for Shanghai's industrial development. Although Meishan is geographically close to Nanjing, it has always belonged to Shanghai in administrative division.
