Some schools in the United States offer Chinese language classes with government support from China.

Saint Mary’s School is a private college preparatory school in Medford, Oregon.

Carly Irvine is in her fourth year of learning Mandarin(普通话).

CARLY IRVINE: “Since China and America are working so closely and our relationship is growing more and more, I think it will be very important in the future to know Chinese.”

Saint Mary’s also teaches Spanish, German and Latin. It added Mandarin in two thousand five. Two years ago, it became the first school in the country to join the Confucius Classroom program.

The program pays about half the costs of a teacher sent to a school in the United States. China’s Education Ministry also provides books and other materials.

Saint Mary’s principal, Frank Phillips, says knowing Chinese will help students in a world where China is quickly gaining economic power.

Zheng Ling, a teacher at Saint Mary’s, came from China in two thousand eight.

ZHENG LING: “People do not know much about China, especially the latest development. So I think this is a chance for them to know more about China, what China is really like. It’s quite different from what it was twenty years ago.”
