On Wednesday Chinese dissident artist-activist Ai Weiwei was released after being held for 80 days without ever being formally charged, but having allegedly "confessed to tax evasion and destroying documents." Though unclear at first, the terms of his release have gradually become known: he cannot leave Beijing for a year (so won't attend next week's opening of his photography exhibition at Asia Society, nor see his "Zodiac Heads" sculptures at the Pulitzer Fountain), and he cannot use Twitter.
So what is his status, exactly? Barbara Pollack explains in an Artnet article:
The Chinese term for Ai Weiwei's status is “guobao houshen,” literally meaning “obtaining a guarantee pending trial.” [...] It allows the Chinese government to save face and retain control over the artist, while he remains free and unindicted for the next year. Ai Weiwei will have to pay back taxes and perhaps pay a fine—his family has maintained his innocence—but he will probably avoid a prison sentence.
Ai has freedom of movement within Beijing, but before he "goes out, he needs to report his whereabouts to them" for a year, the source said, but declined to elaborate who Ai needs to report to.
