Dear Ambassador Liu,
I am writing to urge you to do everything within your power to guarantee the immediate and unconditional release of Ai Weiwei, unless the Chinese authorities can show reasonable grounds for suspecting him of having committed an internationally recognisable criminal offence.
As an artist, Ai Weiwei has uplifted the spirits of people everywhere, as well as representing outside China the very best qualities of its people. By imprisoning him, in this time of international cooperation, China is sending the very worst message it can to the rest to the world. I believe it is in the best interest of China to release him from this unnecessary and politically-motivated imprisonment.
Furthermore, I am urging the Chinese authorities to take effective measures to guarantee freedom of expression, association and assembly in line with China’s Constitution and the International Covenant on Civil and Political Rights which China has signed and declared an intention to ratify.
