Group 1: Economic Impact - Cross-border tourism is not limited to the tourism industry; it has generated a multiplier effect across multiple industries, including accommodation, dining, and retail [1]. - New emerging sectors such as cross-border e-commerce, international logistics, and exhibition services are continuously emerging, facilitating the flow of capital, technology, and talent to border areas [1]. Group 2: Infrastructure Development - The acceleration of international flight routes, expansion of highway networks, and the rapid construction of smart ports are not only serving tourism development but also paving the way for deeper industrial development and economic cooperation [1]. Group 3: Cultural Exchange - Tourism plays a significant role in informal diplomacy, strengthening mutual understanding and connections between people through shared experiences, such as Vietnamese tourists experiencing the "Zhuang March 3" festival in Guangxi [1]. - The development of cross-border tourism fosters friendships and allows people from both countries to become active participants and beneficiaries of development [1].
