Thousands of lorry drivers in South Korea began a strike to protest against rising fuel prices, while also pressing a number of other demands by their union, according to dpa. The Korea Cargo Transport Workers Union, besides demanding lower fuel prices, also demanded higher shipping fees and a minimum wage for lorry drivers. The union claimed that more than 10,000 drivers were taking part in the action, which comes after several rounds of negotiations between the union and government had failed to reach an agreement. Radio reports said that the strike had already led to disruptions in freight transportation and in handling cargo at the country's important ports. The Seoul government fears that the country's export-oriented economy could be damaged by the strike. Minister of Land, Transport and Maritime Affairs Chung Jong Hwan threated tough action would be taken against those drivers involved in "illegal" protest activities. Any road blocks set up by striking drivers would be immediately removed, he said. At the same time, a ministry spokeswoman said that negotiations by the two sides would be continued.
