答案精析：空格所在句的not only…but also…为并列结构，连接his parents and his friends和a matchmaker，意为“不仅……而且……”。根据语义可知，柬埔寨男青年择偶不仅涉及到父母、朋友，也涉及到媒人。空格后的those of the young woman指女方的父母、朋友。因此应选择连接两个并列成分的as well as。

错项排除：A项by way of意为“通过……；经由……”，通常指做事的方式和方法。B项on behalf of意为“代表某人做某事”。根据语义可知，男方亲友不会“通过”或“代表”女方的亲友，故B项错误。D项with regard to意为“关于”，通常用于补充前半句说明的情况，不符合原句中隐含的并列关系。
