[Abstract] China and Central and Eastern European countries are "old friends in history" and "new partners in reality". The CEECs are all countries along the "Belt and Road" Initiative, and an important belt for China's integration into the European economic circle. Exchanges between China and CEECs are cross-regional cooperation promoted in response to changes in international landscape and needs of bilateral common development. However, CEECs are scattered across regions with heterogeneous demands on China, which makes them have particularly urgent requirements for smooth communication channels, timely interaction and feedback, thus increasing the difficulty and cost of communication between China and CEECs. Plus EU elements, the communication situation becomes even more complex. Due to the above reasons, exchanges between China and CEECs will face dilemmas of trade and investment mismatch, uncoordinated relevant policies, overall vague humanistic cognition, and untimely result feedback due to "inadequate communication" for a considerable period of time.

From the perspective of exhibition communication studies, exhibitions can continuously and effectively improve the accuracy of communication through thematic segmentation, competitive display, diversified choices, decentralized decision-making and other characteristic functions, as well as direct, adequate and interactive communication, gradually resolving the "inadequate communication" problem. This paper takes China-CEEC Expo, a communication platform for exchanges between China and CEECs, as the research object, and from the perspective of China as the Expo host and agenda setter, based on the theoretical framework of "regional segmentation - capacity segmentation - demand segmentation - decentralized autonomous decision-making – periodic interactive feedback", makes specific analysis of the four CEEC sub-regions, and demonstrates how the Expo as a service platform for bilateral exchanges can leverage its precision communication mechanism to cope with the "inadequate communication" dilemma, deepen pragmatic cooperation, efficiently serve national strategies, and its necessity, possibility and effectiveness.
