Chinese artist Ai Weiwei to lose design business licence
Officials in China are revoking the business licence of artist Ai Weiwei's company for failing to re-register.
Mr Ai told the BBC he would appeal, saying he was being punished for criticising the government.
He said it was impossible to re-register his Fake Cultural Development firm because officials had confiscated relevant documents.
The move follows his failed bid last week to challenge a tax evasion fine imposed on the firm.
