     Twenty courses provided by 18 top Chinese universities went online on Wednesday, China's latest

attempt to spread teaching resources within the nation and promote (提升) Chinese culture globally.

     These courses cover 20 subjects or lectures given by speakers and professors from several universities, including Zhejiang University, Nankai University and Wuhan University. Most of the courses will focus on

traditional Chinese culture, according to the Ministry of Education. They are available through the

websites of NetEase and China Network Television, as well as icourse.edu.cn, for free.

     Some of the courses will be translated into English and promoted across the rest of the world,

according to NetEase Company, an international body promoting open content among the world's

universities.

     The company has set up a translation team and "will kick off the translation work when we finish the

negotiation (谈判) on intellectual rights with universities", said Zhu Xirui, a senior manager for NetEase

Company.

     "We want to promote Chinese culture to overseas netizens through the program," he said.

     Ding Xiuhong, another manager of NetEase Company, said they had invested (投资) more than 15

million yuan ($2.37 million) in the program.

     "Although we haven't made a profit from 'the program, it will at least help increase our website's page

views," Ding said.

     "I'd like to watch the Chinese elite (精英) classes, such as Chinese literature and poetry, as well as

economy," said Jeremy Scaramuzzi, a teacher at Tsinghua International School.

      He said he was also interested in Chinese classes on political science since that is the subject he

majored in in the United States.
