Mainland entrepreneur Yang Rong has threatened to expose 'every step' of his legal wrangle with the central government, which has refused to accept a lawsuit he filed in the United States. 'We will make public every actual step in this lawsuit from today onwards,' the former chairman of Brilliance China Automotive Holdings, a Shenyang-based carmaker, said yesterday. Mr Yang filed a suit in Washington two months ago claiming compensation of US$690 million from the Liaoning provincial government for assets he claims it stole from him. The justice ministry in Beijing has refused to accept the lawsuit, saying that a foreign court has no jurisdiction in the case. But Jim Slattery, Mr Yang's lawyer in Washington, said while US courts generally had no jurisdiction over units of a foreign government, there were exceptions. 'The facts of the case are unique,' Mr Slattery said. 'We are confident that the facts support the American court taking jurisdiction. China Brilliance was listed on the New York Stock Exchange and has many American investors. 'The Liaoning government, through its wholly owned company Hua Chen Automotive Group, had to conduct a tender offer in the US relating to the unlawful taking of Yang's shares in Brilliance China. 'Filings were made at the US Securities and Exchange Commission.' Mainland media reported yesterday that the justice ministry had returned documents sent by Mr Yang's lawyers, after refusing to send them to Liaoning. Mr Yang said yesterday that he was prepared to prove what he had invested in the company. 'What did Liaoning province invest? The answer is zero.' Liaoning said Mr Yang was never a private businessman but an agent of the state who managed state assets and he was misleadingly presenting himself as a wronged entrepreneur. Businessmen familiar with the case said Liaoning did not intend to contest the case, because this would admit the jurisdiction of the court, but wanted to solve the case through diplomatic channels. However, the central government wants Liaoning to deal with the issue itself.
