To ensure its grip on the message put out by its domestic and international broading service,including CGTN,the government consolidated them in March into a single media group as known Voice of China .

括號its name````里的內容，好像沒謂語 所以不是一個完整的句子對嗎？

that of ，that 又是指代什么呢?

括號內不是一個句子，而是獨立主格結構作狀語，對主句作補充說明。假如去掉括號，則用逗號和主句隔開。其中echoing為目前分詞，its name in English為目前分詞的邏輯主語。that為名詞替代詞，替代前面出現過的一個特指的單數名詞或不可數名詞，在這里that替代the name.

另外，網友句子中的 as known為筆誤，應為 known as.
