汪精卫政权
On September 10, 1943, when Italy signed an armistice with the Allies, the concession was occupied by the Imperial Japanese Army. Later in 1943, the Italian Social Republic (RSI) ceded the concession to Wang Jingwei's Japanese-sponsored Chinese puppet state, the Reorganized National Government of China. The Italians were never to regain control over the concession and the Republic of Italy's surrender of all its rights over it by the peace treaty of 1947, was therefore a mere formality.
