Delegation to Japan explains policy of progress for Tibet

China is working hard to modernize its Qinghai-Tibet Plateau, said Hao Shiyuan, a researcher leading a five-day cultural exchange delegation to Japan that ends Saturday.

"There is no precedent for modernization in plateau areas in the history of mankind," added Hao, who is with the Chinese Academy of Social Sciences.

But China is committed to building a moderately well-off society in an all-around way in 2020. This, Hao said, sets a standard for achieving modernization for all people among its 56 ethnic groups.
