Abstract: Some scholars believe that the “Beijing Treaty” signed  between China and France in 1860 gave the Catholic Church the right to purchase property in China’s interior in the late Qing. In fact, the Beijing Treaty was only an “informal” excuse for France to claim right to purchase land from the Qing government. The Berthemy Convention, which was signed in 1865, was more detrimental than the Beijing Treaty and the “Auguste A1 Gerara Agreement” in 1895, seriously weakened the sovereignty of China and finally established the Catholic Church’s rights in to purchase property in China’s interior.
