 John Service , while under Stilwell 's command , served as a diplomatic observer for both Stilwell and the American Embassy in Chungking . Over the next three months , he sent a series of reports to Chungking , and sparked controversy immediately . Service praised the CPC and compared them to European socialists , rather than the feared U.S.S.R. Service credited the CPC for a clean and superior society in stark contrast to the corruption and chaos he saw in the Nationalist areas controlled by Chiang Kai @-@ shek . He was found bias . After visiting Yan 'an , Service advocated that the United States should work with the forces opposed to the Nationalists , such as the Communists , though he did not advocate abandoning Chiang . This opinion was shared by John Paton Davies , and this position ruined both careers .
