Ma Yansheng, an education counselor at the Chinese embassy, says the number of French students learning Chinese will continue to grow as China's influence and economic strength rise.

"Many of them are very optimistic about China's economic growth and see Chinese as a must-have skill and an effective tool for communication, especially in business," Ma says.

"But language is more than a tool. It is also a bridge for cultural exchange and holds far-reaching implications for strengthening relations between our two countries."

China and France will celebrate the 50th anniversary of diplomatic relations next year, which also marks the 200th anniversary of the inauguration of a chair in Chinese at the College of France, said to be the first in the world.

"The establishment of our diplomatic relations in 1964 has significantly pushed exchanges between our two countries, and education is one of the fields that has benefited greatly from it," says Joel Bellassen, general inspector of Chinese at the French Ministry of Education.

More than half of those in France who are learning Mandarin started in junior high school, indicating that Mandarin has gained greater status in the French basic education system, Bellasen says.

But, Chinese teaching has started to experience some growing pains in recent years as the gap has widened between supply and demand in resources, he says.

There are now about 450 registered Mandarin teachers in France, the education office of the Chinese embassy says. However, only 40 percent of them are officially employed. Nine years ago there were only 135 registered teachers of the language, the office says.

To tackle the shortage of Chinese teachers abroad, the Chinese Ministry of Education has started to dispatch volunteer teachers worldwide. France began to receive volunteers in 2005 and has become one of the countries to receive the highest number.

In July, nearly 200 Mandarin teachers were sent to France to teach more than 5,900 students in schools.

Volunteers like Chang have to pass tests and undergo special training, and those who have experience teaching the language in China are given preference.

In 2008, the Chinese and French ministries of education launched a program of international Mandarin classes in French schools that aims to cultivate and train elites in Mandarin and Chinese culture.

Confucius Institutes also play a major role in promoting China, its language and culture in France. There are 15 Confucius Institutes in the country, and they offer a total of 476 Mandarin classes, the education office at the Chinese embassy says.

The French ministries of education and foreign affairs have also proposed launching the first training program of Mandarin teachers in France on the occasion of the 50th anniversary of Sino-French diplomatic relations next year, Bellassen says.

"While the number of students and Chinese classes continues to grow, ensuring teaching quality is the next key thing," he says. "And we need to have more training programs and hire more trainers for our Mandarin teachers."
