在目前可考文献资料中,笔者没有看到任何直接反映渤海与后东突厥汗国之间交涉的具体、完整的记述,突厥从未正面出现在渤海对外交涉的舞台上。但实际上,直到745年后东突厥汗国被回纥灭亡,渤海早期的对外交涉,特别是对唐朝及周边部族关系上的任何重大事件,都与后东突厥汗国有着千丝万缕的关联。 In the current testable literature, I did not see any concrete and complete account of the negotiations directly between the Bohai Sea and the Eastern Turkestan Khanate. The Turks never appeared on the stage of foreign negotiation in the Bohai Sea. In fact, it was not until July 745 that the Eastern Turkestan Khanate was exterminated. Early Bohai Sea foreign affairs, especially any major incident in the relations with the Tang and neighboring tribes, were inextricably linked with the post-East Turkistan Khanate Associated.
