The New Fourth Army Incident (Chinese: 新四軍事件), also known as the South Anhui Incident or Wannan Incident (Chinese: 皖南事變), occurred in China in January 1941 during the Second Sino-Japanese War, during which the Chinese Civil War was in theory suspended, uniting the Communists and Nationalists under a United Front against the Japanese. It is significant as the end of real cooperation between the Nationalists and Communists. Today, ROC and PRC historians view the New Fourth Army Incident differently. From the ROC point of view, the Communists attacked first and it was a punishment for the Communist insubordination; from the PRC view, it was Nationalist treachery.[2][3]
