Mainland entrepreneur Yang Rong has accused the provincial governor he is suing in a United States court of confusion and inaccuracy, while his lawyer said they might add the central government to the indictment. The former chairman of Brilliance China Automotive Holdings, a car company based in Shenyang, filed a suit in Washington in August, claiming compensation of US$690 million from the Liaoning government for assets he claims it stole from him. At a news conference before the National Day holiday, Liaoning governor Bo Xilai said Mr Yang was not a private businessman, but a manager and representative of state assets. 'In taking over the state assets of Brilliance China, our province was implementing state policy,' Mr Bo said. Liaoning deputy secretary-general Wang Jindi read out statements Mr Yang purportedly made in September 1993 that he was a custodian of state assets. On Tuesday, Mr Yang said the documents quoted by Mr Bo were inapplicable. 'The document dates that Governor Bo cited could not apply to Brilliance China. They were about an unrelated company, Brilliance Holdings Limited, not Brilliance China Automotive Holdings. They had nothing to do with Brilliance China and Liaoning's lawyers know that,' said Mr Yang, who fled to the United States last year. 'To use a press conference instead of a court or a negotiating place to prove ownership invites mistakes that mislead the press and the public. The court looks at who invested in the asset. I am prepared to prove what I invested in Brilliance China. What did Liaoning province invest? The answer is zero.' Mr Yang's lawyer, Jim Slattery, said the key information Mr Bo confirmed was that Liaoning was acting under instructions from state government documents. 'This means that we will have to consider adding the central government as a defendant in our case in Washington,' Mr Slattery said. China International Law Association deputy chairman Zhou Zhonghai said the Liaoning government should not respond to the suit. 'The accused should be the Chinese partners of Brilliance China and not the Liaoning government, even less the leaders of that government. The issue should be settled through diplomatic channels. That is the only correct choice,' he said. The lawsuit is the first case a US citizen has brought against a Chinese provincial government. The plaintiffs are Mr Yang, 46, a US permanent resident who holds a Hong Kong identity card, and his wife, Rhea Yeung, who is a US citizen.
