In December 1945, President Truman sent George Marshall on the Marshall mission to mediate between the CCP and GMD. He persuaded a ceasefire in January 1946. He also persuaded Jiang to call a maijor conference which all of China's maijor parties attended to agree on a coalition. However, Jiang tried to change the agreement to create autocratic government. The other parties withdrew and in Spring 1946 fighting started again.
