With the economic reforms under Deng Xiaoping and the death of Mao Zedong, the PRC's attitude toward overseas Chinese became much more favourable, and overseas Chinese were seen as a source of capital and expertise. In the 1990s, the PRC's efforts toward overseas Chinese became mostly focused on maintaining the loyalty of "newly overseas Chinese", which consisted of mostly graduate students having moved, either temporarily or permanently. In recent years, there have been summer camps which have been set up by organizations such as the China Institute and Confucius Institute in which overseas Chinese youths may attend to learn first-hand about its own ancestral Chinese culture as well as the language. In 2013, "100 overseas Chinese youth embarked on their root-seeking journey in Hunan." Textbooks for Chinese schools are also distributed by the government of the People's Republic of China.
