(Reuters) - No talking, no tweeting and no travel for a year -- these are some of the conditions of Chinese dissident artist Ai Weiwei's release from more than two months in detention, underscoring Beijing's efforts to muzzle dissent.

The comprehensive gag on Ai, who is not allowed to post anything on Twitter or accept interviews for a year, raises questions about the Chinese government's repeated claims that his detention was based on economic crimes.

After almost three months of detention by Chinese government authorities, Ai Weiwei was released yesterday on bail and returned to his home in Beijing.
