since缘由状语从句

Andsince India has banned the export of finished vaccines while it serves domesticneeds, Mr Jadhav says that SII cannot fulfill its commitments to Covax, aglobal vaccine-sharing programme, and cannot deliver supplies to Europe andBritain.

since缘由状语从句是宾语从句的状语从句，放在句首多见么？

谢谢各位老师！

你也可以理解since从句是主句 sb says是什么原因状语，所以某人说了如下的话。如此就没有宾语从句是什么原因状语移至句首的问题了。
