The force of globalization has greatly challenged people’s conceptualization of national identity. The traditional definition of national identity as being distinct, stable and generated by such internal factors as ethnic, religion, citizenship and so on, has been replaced by the understanding that national identity is invested with more dynamic and complex features and is actually constructed differently in different situations. By following Van Dijk’s socio-cognitive perspective in critical discourse analysis and drawing on the 47 news reports collected on the websites (...) of People’s Daily Online and Xinhuanet, this study explores how China’s national identities are negotiated in its news reports of the Sino-US trade war. It is found that China’s news reports have constructed three types of Sino-US relations, namely, antagonistic, negotiatory and cooperative relations. Out of these relations, China has been constructed as victim of the trade war, defender of free trade, driver for negotiations and beneficiary of mutual cooperation. The construction of these identities and relations is realized through constructive, destructive, justification and transformation strategies. It is further found that the diversity of both China’s national identities and Sino-US relations in China’s news reports is the result of the political, social and economic differences between the two countries.
