The Shandong Problem or Shandong Question (simplified Chinese: 山东问题; traditional Chinese: 山東問題; pinyin: Shāndōng wèntí, Japanese: 山東問題, Santō mondai) was a dispute over Article 156 of the Treaty of Versailles in 1919, which dealt with the concession of the Shandong Peninsula. It was resolved in China's favor in 1922. The US, finding itself isolated by all Great Powers, agreed to the Japanese, British and French demands. The Chinese public became outraged by the eventual treaty, accusing the Chinese government of selling out, and became disappointed by Wilson's failed promises.
