The Belt and Road Initiative (BRI) has attracted support and critique for its legitimacy and potential success. Its opponents see challenges more than prospects because of American inattention and resistance, and its proponents see prospects more than challenges because of the attention from the rest of the world. While both sides use valid reasons for their explicit or implicit views, they focus on the legitimacy by its taken-for-granted status. The BRI project as innovation is at the legitimisation process stage. To address the legitimisation of the BRI project innovation, we use rhetorical theory to analyse the Chinese official report in 2019, the American versus European media response to the BRI project and the US direct response to the BRI in the Indo-Pacific Strategy in 2019. Our exploratory findings show insights into the subjects, industries and regions. Firstly, the American media attention far exceeds the European media attention. Secondly, the American media attention and direct response to the BRI highlight the political issues, and the European media attention highlights economic issues. The Chinese official report mentions European countries, and excludes the USA. Thirdly, it uses Pakistan more frequently than other countries or regions in its achievement report, but the US has not mentioned Pakistan at all in its Indo-Pacific Strategy. Fourthly, the US political logic diverges from the logic of the BRI project, while the European economic logic converges to the logic of the BRI project. Based on these findings, we contribute to the legitimisation process of innovation, rhetorical theory and policy implications in the world.
