On the other hand, Luvsanvandan (1959) proposed a much broader "Mongolian language" consisting of a Central dialect (Khalkha, Chakhar, Ordos), an Eastern dialect (Kharchin, Khorchin), a Western dialect (Oirat, Kalmyk), and a Northern dialect (consisting of two Buryat varieties). Additionally, the "Language Policy in the People’s Republic of China: Theory and Practice Since 1949", states that Mongolian can be classified into four dialects: the Khalkha dialect in the middle, the Horcin-Haracin dialect in the East, Oriat-Hilimag in the west, and Bargu-Buriyad in the north.
