China's work safety watchdog will spend three years to find and tackle flaws in oil pipelines, according to the State Administration of Work Safety.

The work safety committee of the State Council has recently issued a notice urging more efforts to crack down on damage on oil pipelines, including unauthorized construction nearby, said the administration on Saturday.

A campaign to pinpoint risks of oil pipelines started at the end of last year, with about 30,000 flaws already found, the notice said.

The efforts to address these problems have been moving slowly due to various difficulties, including a lack of funds, but the State Council has set up a task force to facilitate the processes, it said.

An oil pipeline blast killed 62 people in Qingdao, east China's Shandong Province, in November last year.
