U.S. schools lack resources and teachers to meet the demand for Chinese language and culture studies, despite the growing importance of China's economic and political relationship with the United States, according to a study released by the Asia Society on Tuesday.

　　The study, designed to expand awareness of the need for more classes and teacher training, questioned several dozen experts in a variety of fields to see what it would take to have 5 percent of American high school students learning Chinese by 2015.

　　China has become an increasingly important U.S. trade partner. Its economy is growing at about 9 percent a year and could become the second largest in the world, after the United States, in the next two to three decades.
