Well, I guess is more appropriate calling it Lunar New Year instead of Chinese New Year, as not only chinese celebrate it, So does the japanese, korean, Vietnamese.
Obama also mentioned..
In a message posted on the White House Web site, the president sent his “warmest wishes to Asian-Americans and Pacific Islanders, the people of Asia, and all those around the world who are celebrating the Lunar New Year,” China’s state-run Xinhua news agency reported.

Chinese New Year is celebrated in countries and territories with significant Han Chinese populations (Chinatowns), such as Mainland China, Hong Kong, Macau, Singapore, Taiwan, Indonesia, Laos, Malaysia, the Philippines, and Thailand. Chinese New Year is considered a major holiday for the Chinese and has had influence on the new year celebrations of its geographic neighbors, as well as cultures with whom the Chinese have had extensive interaction. These include Koreans (Seollal), Tibetans andBhutanese (Losar), Mongolians (Tsagaan Sar), Vietnamese (Tết), and the Japanese before 1873 (Oshogatsu).
In countries such as Australia, Canada and the United States, although Chinese New Year is not an official holiday, many ethnic Chinese hold large celebrations and Australia Post, Canada Post, and the US Postal Service issue New Year’s themed stamps.
