Large-scale riots would be 'inevitable' if the Government continued to suppress disgruntled workers by force and ignore their problems, exiled activist Han Dongfang warned yesterday. Instead of mobilising police or even the army to quell industrial unrest, the Government should work hand-in-hand with the workers, Mr Han said in Hong Kong. Protests in Liaoyang followed a demonstration by about 20,000 miners at the Yanjiazhan mine in Huludao city, Liaoning, early this year. They blocked a railway line to protest against the mine's bankruptcy. The protest was later quelled by the People's Liberation Army. But labour unrest has become increasingly frequent and widespread not just in Liaoning but in provinces like Jilin and Inner Mongolia as well, according to Mr Han. Mr Han said the main problem was the poor management of China's state-owned enterprises. 'For the past 20 years the Government has refused to look into the root causes of problems. Unfortunately, they adopted a policy of getting rid of workers. The problem is getting worse but the ability of the state to deal with the problem is diminishing,' he said. He urged the Government to open dialogue with workers and put in place an effective social security system.
