Against the background of intensified collision of global value logic and rapid adjustment of the world political and economic order，technological revolution and industrial upgrading are reshaping the logic of communication，and enhancing the influence of China’s foreign communication has become the focus of attention from all walks of life. This paper has sorted out the various opportunities of AIGC technology empowering international communication，including assisted editorial，precise placement，intelligent interaction，content production，intelligent auditing，etc. Meanwhile，it has pointed out the challenges of content homogenisation and copyright disputes，algorithmic bias and uneven distribution of information power，and China’s foreign discourse power has not yet been matched with the national power in the practice of AIGC technology，etc. It also puts forward the proposal of building communication subjects with multi-channel communication matrix，guiding the communication logic with cognitive logic，and improving the influence of China’s foreign communication with multi-channel communication matrix. At the end of the paper，we put forward some practical paths of international communication in the new era，such as building a communication body with a multi-channel communication matrix，guiding the deployment and application of technology with cognitive logic，systematically transforming technological achievements in a demand-oriented manner，and promoting the practice of technological application with the concept of value alignment，with the hope of providing references to the systematic construction of China’s oversea communication.
