Language security is an important part of national security, and in the current complex international environment, the issue of language security is becoming more and more prominent and has become an unignorable part of national security strategy. As the bridge and link of international communication, foreign language talents’ language skills and the level of national security awareness directly affect our country’s international image and the effect of international communication. Therefore, the establishment of a foreign language talent cultivation mode based on the concept of language security is not only an important way to improve the quality of foreign language education but also a realistic need to safeguard national security and promote international exchanges. Starting from the influence of the language security concept on foreign language talent cultivation, this paper analyzes the foreign language talent cultivation mode based on the language security concept, with a view to providing new ideas and methods for the development of foreign language education.
