Dialogic interaction (DI) paradigm, as an important paradigm in interpreting studies, indicates that interpreters, not limited to the role of sound transmitter, simultaneously have the function of “coordinating”. Based on DI paradigm, this paper discusses the function of “coordinating” from an intercultural perspective, proposing that the function of “coordinating” is just a manifestation of interpreters' subjectivity in interpretation. Through some detailed examples and analyses from three intercultural dimensions (individualism vs. collectivism, high context vs. low context, and power distance), this paper elaborates how interpreters use appropriate strategies to realize the aim of maintaining a smooth communication between the speaker and the listener. Finally, by combining interpreters' role of “cultural mediator” and interpreters' subjectivity, this paper attempts to prove that in DI paradigm, interpreters should give a full play to their subjectivity, thus helping to enhance the interpreting effectiveness and making their due contribution to the successful conversation between the speaker and the listener.
