This paper examines the linguistic security issues in “the Belt and Road Initiatives” and proposes strategic plans and policy suggestions.Linguistic security is an increasingly important topic in macro-sociolinguistics and can be crucial in the realization of “the Belt and Road Initiatives”.Drawing on an extensive survey of linguistic security theories and practice,I propose four categories of linguistic security strategies:inner source linguistic security,external source linguistic security,dual source linguistic security,and multiple source linguistic security.Inner source linguistic security refers to the security issues of the languages and language resources inside China,including foreign languages,dialects,and minority languages in China.External source linguistic security refers to the security issues in language situations of the countries on “the Belt and Road”,and the potential risks that Chinese enterprises may face as a result of not knowing the local languages of “the Belt and Road” countries.Dual source linguistic security refers to the security issues in the bordering regions where linguistic risks may come from both inside China and the bordering countries.Multiple source linguistic security refers to the security issues involving new and complex factors such as terrorism,Internet security,and voicing potentials.Based on the four linguistic security perspectives,I propose four policy suggestions:1)focusing on linguistic security planning studies of “the Belt and Road” countries,2)initiating strategic studies on cultural security,3)exploring the governing capabilities of the bordering regions,and 4)establishing risk assessment and coping mechanisms of linguistic security.
