Around 80% of China’s bioscience still depends on US-based databases, according to a scientist at the government-affiliated Chinese Academy of Sciences, who asked not to be identified because he’s not authorized to speak publicly.The US move to guard some of its most sensitive data is already impacting some colleagues, who have sought workarounds including collaborating with scientists in countries with free access, said the person, who estimates it could take between five and 10 years for China to be able to rely on its own databases. The sentiment in the industry is generally pessimistic, with expectations that the ability to share information will deteriorate further, the person said.
