(24 November 2017) At the end of October, the National Science Library, the Chinese Academy of Sciences (NSL, CAS), the National Science and Technology Library (NSTL) and ShanghaiTech University Library signed the Open Access 2020 Initiative. The Director of NSL, CAS, Mr. LIU Huizhou, said that open access is beneficial to scientific research, scientific communication and the development of a creative society. The signature of OA2020 means that China will actively contribute to the reform of the global scientific communication system. It will also accelerate the implementation of CAS’s open access policy.
China has long supported open access. In 2004, CAS signed Berlin Declaration on Open Access. In 2013, the National Natural Science Foundation of China (NSFC) and CAS signed GRC Action Plan on Open Access for Publications. In 2014, NSTL attended SCOAP3, and from then on Chinese authors can publish articles for free in journals funded by SCOAP3.
