DALIAN, July 26 (Xinhua) -- China has stopped the Dalian oil spill from reaching international waters, an official said Monday, admitting the clean-up work was "arduous."Dai Yulin, vice mayor of Dalian City, Liaoning Province, where oil pipelines exploded on July 16, said workers had contained the oil slick, stopping it from reaching the open sea."But the next step, which is clearing it up, is an arduous task," Dai told a press briefing."Some of the slick has been mopped up, but it's not easy to get rid of the rest," he said.The clean-up has involved 266 oil-skimming vessels and 8,150 fishing boats, Dai told reporters.Maritime agencies and oil companies have laid down more than 40,000 meters of oil barriers and 65 tonnes of oil absorbent mats, he said.Despite this, oil could still be seen on some beaches.An explosion hit an oil pipeline 0.9 meters in diameter at 6:20 p.m. on July 16 and triggered an adjacent smaller pipeline to explode near Dalian Xingang Port. Both pipelines are owned by China's No.1 oil and gas producer CNPC.Improper injections of strongly oxidizing desulfurizer into the oil pipeline after a 300,000-tonne tanker had finished unloading its oil caused the explosion, results of a State Administration of Work Safety and Ministry of Public Security investigation showed Friday.

LANZHOU, Aug. 24 (Xinhua) -- China plans to spend 2.23 billion yuan (328 million U.S. dollars) to improve disaster prevention systems in a mountainous northwest China town devastated by a landslide earlier this month, local officials said Tuesday.The planned multi-billion yuan project to prevent further geological disasters in Zhouqu County, south of Gansu Province, had passed reviews by experts from the Ministry of Land and Resources, said Guo Yuhu, vice-director of the provincial land and resources department.The plan is scheduled to be carried out in three phases from 2010 to 2012, Guo said.Guo noted that the project includes improving disaster warning systems, drawing up emergency resettlement plans, conducting a thorough study of the geological disaster hazards, and setting up a capable monitoring network.A late-night avalanche of mud and rocks roared down the mountain slopes in the county seat of Zhouqu on Aug. 8, burying villages and blocking the Bailong River, a major regional river.At least 1,447 people were killed and 318 remain missing, according to the latest government information.The mudslide left a thick layer of sludge, about 5 kilometer long and 500 meters wide, in the center of the town. Many bodies are believed to be buried in the mud, but authorities banned their recovery on Sunday due to concerns over public health.
