A nationwide monitoring system is being set up to keep track of the flow and employment of rural labourers in cities. According to the official Xinhua yesterday, the plan came out of a recent labour conference in Fushan, Guangdong. Eighty checkpoints will be set up - 31 in cities which import rural workers, 41 which export them and eight transport hubs where workers converge. The Ministry of Labour and Social Security will be responsible for the management of the checkpoints. The checkpoints will study the volume and flow of the workers and their impact on the economy and social developments in both their home villages and destinations. The ability of cities to absorb migrant workers and their effect on local labour markets would be investigated, Xinhua said. The news agency said the authorities hoped that, through careful study of the information, they could effectively regulate the flow of the migrant workers. Earlier reports said there were about 110 million unemployed rural labourers. Every year, 13 million new labourers join the market.
