The statement made by a Foreign Ministry spokesperson at a regular press conference is a window for the world to understand China and its foreign policy on the one hand,and a sign expressing the Chinese position and attitude towards the events at home and abroad on the other hand.From the perspective of the appraisal theory,this paper reveals how the spokesperson employs the engagement resources to expand or contract the dialogue space to convey the Chinese stance to the audience.Through both quantitative and qualitative methods,it is found that even though dialogic expansion resources are chosen in preference by the spokesperson,all kinds of engagement resources integrate with each other to help the spokesperson negotiate their dialogic space with the audience.
