 Truman then sent another representative to China , General Albert Wedemeyer , who had commanded U.S. troops in China during the war , on a fact finding mission . Again , the Dixie Mission in Yan 'an hosted the presidential mission . Wedemeyer reported that U.S. interests were best served by continued support for the Nationalist government , but Truman suppressed the report because he was waiting to see who would win and refused to expand aid the Nationalists so as to avoid involvement in the Chinese Civil War . After Wedemeyer 's visit , the U.S. packed up operations in Yan 'an and liquidated everything that could not be transported aboard a C @-@ 47 . On 11 March 1947 , the last members of the Dixie Mission left Yan 'an .
