On the anniversary of the “June 4” incident, we again express our gravest concern for the fates of those who have been persecuted for their support of democratic progress in China. We hope that the Chinese government can abide by the Constitution of the People’s Republic of China, which acknowledges the citizens’ rights to assembly, association, and freedom of press and expression, and immediately release all prisoners of conscience, including Wang Dan, Ren Wanding, Wei Jingsheng, Wang Juntao, Han Dongfang, Liu Xiaobo, and many others.
