Ethnically, the Khitans were Mongolic peoples, originating from the Xianbei people (who in turn originated from Donghu people). Their cultures were Proto and Pan-Mongolic and so were their languages. So Sun is ethnically a Mongol.

However, he was raised in the Eastern Turkic Khaganate, hence he grew up culturally Turk and speaking a Turkic language.

Sun also though he was ethnically Turk before finding out he is actually Khitan.

Think of it like a modern adopted child finding out he is actually Korean not Chinese.
