Actually, more like a combination MGI/labour dispute. For the last six days, thousands of former employees of the giant state-owned engineering firm Gezhouba, which was the main contractor on the Three Gorges Dam project have been demonstrating in Yichang, a city in central Hubei, over pensions and health insurance benefits. The demonstrators - all apparently in their sixties and seventies - are apparently designed to bring traffic flow to a halt in a major central Chinese communications artery, which also happens to contain the company headquarters. Nobody moves till grandad gets his wedge.
Thus far, the authorities have not responded violently: perhaps because of the age of the protestors and perhaps because the protestors are making it clear that their gripe is exclusivley with Gezhouba, and therefore with that part of the central government responsible for it. Latest reports in Chinese state media say that teh company has offered some concessions, that the roads are partially open, and that the demonstrations continue.
