Chinese cities have reached the leading level in data opening in the world, and the US cities remain the top in the field, said Fan Jiajia, associate researcher of Information Research Institute at the Shanghai Academy of Social Sciences, at a forum of 2021 World Artificial Intelligence Conference on Saturday.
