A Hong Kong citizen who threatened to set himself on fire at yesterday's opening ceremony of the Beijing municipal People's Congress is under house arrest, his lawyer said. Yu Fung-chuen, a 61-year-old Hong Kong permanent resident, was detained in Beijing yesterday morning after he wrote to Beijing police saying he would protest outside the offices of the municipal party committee and the municipal people's congress. Mr Yu's lawyer, Shu Jie, said he believed Mr Yu planned to torch himself if his petition was not accepted because his client stated this intention in a will late last year. It is the first time the former businessman has threatened to take drastic action during the city's congress, even though he has written letters to the Beijing government every year. Mr Yu has been protesting against the city government for allegedly failing to carry out a 1994 ruling by the China International Economic and Trade Arbitration Commission that a company owned by the Beijing municipal Science and Technology Commission should pay Mr Yu US$911,547 and 119,000 yuan for breaching an agreement with a trade company owned by the businessman. Mr Yu's company supplied 1.7 million tonnes of iron sand to the company for refinement, but the latter failed to deliver quality pig iron as agreed, according to a court document provided by the lawyer. 'He used to live on The Peak in Hong Kong and he lost his entire fortune because he paid for the container carriers and warehouses, and failed to deliver the products to his trade partners in South Korea,' Mr Shu said.
