Abstract: This paper studies the value, challenges and countermeasures of traditional sports culture exchange of cross-border ethnic
groups between China and Myanmar under the "Belt and Road" Initiative with the help of literature studies and other methods. Values:It promotes cultural identity and safeguards border stability; shortens the emotional distance and facilitates people-to-people bond;expands the space for dialogue and promotes economic and trade cooperation; and drives exchanges and mutual learning to achieve common prosperity. Challenges: The unbalanced economic development leads to unequal dialogue between the two countries; severe challenges in non-traditional security fields; potential risks from Myanmar's political-strategic shift; interference and obstruction
imposed by hostile forces abroad; and the impact of the COVID-19 outbreak on cultural exchanges. Countermeasures: To strengthen
government policy communication, cooperation and strategic layout; to build a diversified exchange platform, smooth interactive
exchange channels; to integrate special cultural resources and shape the cultural exchange brand; to adopt a two-way exchange mode; and to build a full-media communication matrix thus forming a three-dimensional communication pattern.
