This paper explores the news trustworthiness and media credibility of The Economist’s news report on 9 July 2009, and the communicative roles of 846 readers’ responses. Theoretically guided by news translation and cultural resistance and the online public sphere, we applied online field observation and discourse analysis and achieved two main findings: First, although the news report covered the Xinjiang riots with comprehensive and attractive details, it violated the core journalism value of media credibility and journalistic objectivity by providing misleading pictures and significant unreliable and biased coverage. Second, the major communicative roles of the online readers’ responses generally match Dahlberg’s six conditions of an ideal online public sphere, which is still challenging but promising to realize.
