I know of several Buddhist groups who chant to see in the New Year. I can't imagine why, except that it shows more attachment to one day than another, especially as the day is of no special significance to Buddhists.
Buddha Shakyamuni said in the sutras that practice on special days even culturally specific special days is significant. And basically the whole world observes Western New Year now.
So Russian Buddhists can celebrate Western, then Russian Othodox, then Tibetan and Mongolian New Years!
